When beetles were abundant, all rose cultivars were severely defoliated regardless of bloom color. All of the trees with 61.0 cm (24 in) root balls dipped in the low rate of Dursban® survived and showed no signs of phytotoxicity. Over the years, he has used pheromone traps, such as The RESCUE!® Japanese & Oriental Beetle Trap, to protect the prized rose bushes and other plants in his own back yard. However, there were consistently fewer live grubs recovered from the root balls dipped 2 or 5 min compared with the number of live grubs recovered from root balls dipped for 1 min. “Use the traps and you’ll be happy with them,” exclaims Dr. Klein. The tested strains are native to Switzerland and were isolated from related scarab beetles. Japanese Beetle Trap catches the Japanese Beetle, a destructive pest that infests and destroys over 300 varieties of ornamental plants; Can also be used to catch the Oriental beetle which feeds on roots of turfgrass, nursery stock, greenhouse ornamental crops and fruit Avoid Japanese beetle traps if you don’t want to attract more beetles. All rights reserved. My analyses also revealed significant selection for larger wings in females but, contrary to prediction, direct sexual selection favors smaller body size in females. The RESCUE!® Japanese & Oriental Beetle Trap. Presence of one grub species did not affect distribution of the other species. So WRONG! If a yard looks attractive, they will come in for a meal– unless a trap is set to intercept them. pathogenic in host grubs. Cultivars sustaining the most damage by leafrollers were ‘Richard Wallace’, ‘Firebird’, and ‘Black Knight’. Avoid Japanese beetle traps. Furthermore, the microbiota associated with the isolated nematode was characterized using a metabarcoding approach. We were throwing out ideas,” Harrison said. The results showed that larval mortality was higher for pre-wintering larvae than post-wintering ones. In 1996, the influence of root ball size, soil type, and dip time on the efficacy of Dursban® 50WP, Dursban® 4E, and Oftanol® 2F (isofenphos) for white grub control in dipped B&B nursery stock was evaluated. (99). In Quebec (Canada), viticulture is practiced at the fringe of what is known as a cool climate area. The Japanese beetle's life cycle begins in early summer when females emerge from overwintering in the ground. Add to cart. The mortality of the host after five days varied from 54% to 60%, depending on nematodes concentration. Species of Heteroptera were found either on the silk and on the ears. A modified Match Index generated by the computer program CLIMEX 4.3 is used to predict the potential distribution of the beetle to provide a logical rationale for the implementation of quarantine, monitoring and eradication measures. and because natural enemies are adequate to keep its populations lo, are based upon misidentifications, and its establishment, quarantine pest (166), and it has similar status with. These results support the mobility hypothesis and partially explain the evolution of female-biased size dimorphism in this species. The Japanese beetle (Popillia japonica) is one of the most destructive invasive pests in North America, causing significant economic impact to many fruit crops, turfgrass and the nursery industry. The attraction was also observed with ether extracts of the body surface of both sexes. As infestations increase on farms, growers should be vigilant about control in order to prevent extensive leaf damage. The Quebec viticultural industry has consistently developed over ca. Little was known on the biology of the Japanese beetle, Popillia japonica Newman, upon its discovery in a New Jersey nursery in 1916. Both of these pests cause defoliation of the plants resulting in reduced plant fitness and aesthetic injury. It is now found throughout the eastern U.S., except for Florida, and continues to move westward. “The first meeting we had, I can still remember the man from the Department of Agriculture, Jerry Cochran. Currently, P. japonica has colonized almost all of the eastern United States and is moving into the Western Region with increasing reports in the Midwest Region of the country, where considerable population growth has been observed (POTTER; ... Popillia japonica is a significant insect pest due to its generalist feeding habits. In the USA, mainly insecticides are used to control the Japanese beetle. The damage observed in mature ears was associated with the infestation in the milk stage. Advances in understanding host plant resistance, entomopathogens, and other biorational approaches may provide more options for integrated management. virulence or broader host range. Japanese Beetles were accidentally introduced to the east coast in 1916 in a shipment of iris bulbs. And Jerry said, ‘You can’t go there. ), 8 species and cultivars of lindens (Tilia spp. Using a simulation model, we evaluated three potential management options to slow the spread of A. planipennis in discrete outlier sites: (i) removing ash trees to reduce available host phloem resource, (ii) girdling ash trees to, The work was conducted in commercial field corn at the National Corn and Sorghum Research Center, CNPMS-Embrapa in Sete Lagoas, MG, Brazil. The diet gave the best survival and heaviest pupae and was previously used for rearing larvae of the New Zealand grass grub, Costelytra zealandica (White). These favorable conditions and an absence of natural enemies contributed to beetles inhabiting 26 states in the midwestern, eastern and southeastern United States. The Japanese beetle (Popillia japonica) is a species of scarab beetle.The adult measures 15 mm (0.6 in) in length and 10 mm (0.4 in) in width, has iridescent copper-colored elytra and a green thorax and head. Adaptations mediating their host finding, dietary range, mating, and oviposition are discussed. This review emphasizes recent research on the beetle's biology and management. It was accidentally introduced to the USA in the beginning of the 20 th century (Fleming, 1972). no indication of recommencement of pheromone production (80). more responsible for cycles of outbreak and decline? Our results suggest that the bacterial community of the isolated nematode is dominated by bacteria belonging to the genus Ochrobactrum, that includes entomopathogenic species. The beetles, however, are strong fliers and travel several miles, touching down at random intervals to see what's available to eat. Made of highly durable, double-layered nylon, the bag withstands bad weather and the test of time. isolated infestations under some circumstances (e.g., 45, shipment. From that moment onwards, the insect has spread invading several US states, Canada, the Azores, Italy and, recently, Switzerland. Best Japanese Beetle Trap Review – Top Rated Models in 2020 with Buying Guide . Japanese beetle numbers continue to increase in the weekly trap counts conducted by University of Minnesota researchers in Forest Lake, Hastings, Chanhassen, and Rosemount. Visual diagnosis and qPCR detection agreed for 80.9% of the beetles tested. There were no significant differences in grub survival due to dip time (1, 2, and 5 min). Proliferation of. This means you are unnecessarily attracting beetles to your yard, resulting in a larger problem. The southern parts of the Canadian Maritimes and eastern British Columbia and parts of Washington and Oregon also appear suitable. Sexual selection favored rounder bodies in females and more tapered bodies in males, whereas, in both sexes, the effect of wing shape appears less important to fitness than wing size. Green Earth Japanese Beetle Trap quantity. Reducing ash phloem by removing ash trees decreased population size within treated areas but did not reduce the radial spread, population size, or larval consumption of ash phloem beyond treated areas. Clonal grape plants presented on. Description; Description. host suitability than are volatiles released constituti, tracted to a range of plants regardless of their suitability suggests that acceptance. However, they also work well for various other flower visiting scarab, cerambycid beetles, mordellids, etc. natural enemies, as well as present and future management strategies. The ratios of males to females on vines and shoots were 1.794 and 1.732, respectively. Despite ongoing regulatory efforts, the Japanese beetle remains a threat as an invasive species. Ovavesicula popilliae is promising as a classical biological control agent for Japanese beetle, but outside of surveys completed in Connecticut and Michigan little is known about its geographic distribution in North America. Scramble competition can select for trait characteristics that optimize locomotion; for example, long and slender wings should be favored if aerial speed is important to mating success. Nursery fields in counties of Michigan and Ohio with the highest adult, dophytic tall fescue in choice tests (29). Because this generally, Cancellation of traditional soil insecticides, tion on resistant plants to landscape architects, city foresters, and retail personnel, tional propagation or transgenic plant technology. ‘Sugar Tyme,’ in particular, was almost untouched by gypsy moth or fall cankerworm (less than 1.3% defoliation). In 1999, trees with 61.0 cm (24 in) root balls were dipped in either 0.453, 0.226 or 0.113 kg ai/378.5 liter (1, 0.5 or 0.25 lbs ai/100 gal) of Dursban® 4E for 2 mins. Adults feed on leaves, flowers, or fruits of more than 300 plant species. A microsporidian pathogen of Japanese beetle, Ovavesicula popilliae, discovered in 1985, proliferates in the malpighian tubules of larvae and adults, disrupting waste-removal, mineral filtering, and fluid balance in heavily infected individuals. So there it is: Myths busted and facts prove the case for pheromone traps... specifically the RESCUE!® Japanese and Oriental Beetle Trap! Japanese Beetle Traps Control of Japanese Beetles Using Traps. Japanese beetles (Popillia japonica) were first found in the United States in 1916, after being accidentally introduced into New Jersey. (Boddie) were the predominant species. These relatives of the Japanese beetle damage the roots of turfgrass, fruit and ornamental plants, and they only fly at night – making hand-picking nearly impossible. were evaluated for resistance to naturally occurring insect pests at replicated plantings in Detroit, Lansing, and Cadillac, Michigan. Multivariate selection analyses support the prediction that smaller body size and larger wings in males benefit their mating success. Cultivar Response to the Lesser Canna Leafroller, Geshna cannalis (Quaintance), and the Japanese Beetle, Popillia japonica (Newman), Insecticide Dips for Control of Japanese Beetle and Other Soil-Infesting White Grubs in B&B Nursery Stock, On the California border, exotic pests pose growing problem for California, Relative Susceptibility of Cultivars of Flowering Crabapples, Lindens, and Roses to Defoliation by Japanese Beetles, Evaluation of Selected Crabapple Cultivars for Insect Resistance, Aggregative Distribution Pattern of the Japanese Beetle, Popillia japonica NEWMAN (Coleoptera : Scarabaeidae), and the Role of Former Occupants in the Formation of an Aggregation, Artificial Diets for Third Instar Japanese Beetle (Coleoptera: Scarabaeidae), Preferences of Japanese Beetle and Southern Masked Chafer (Coleoptera: Scarabaeidae) Grubs Among Cool-Season Turfgrasses, Bacillus thuringiensis serovar japonensis Strain Buibui for Control of Japanese and Oriental Beetle Larvae (Coleoptera: Scarabaeidae), Mass Trapping for Suppression of Japanese Beetles, Japanese beetle, Popillia japonica Newman (Coleoptera: Scarabaeidae): Rate of movement and potential distribution of an immigrant species, Pollinator conservation in urban landscapes. Both BLAST search and the phylogenetic maximum likelihood tree inferred from 18S rRNA sequences confirm the attribution of the isolated nematode to the genus Oscheius (Nematoda Rhabditidae). Abstract. However, it should be noted that traps will only help prevent the adults from feeding on certain plants and shrubs. Enlist neighbors to battle the beetles, too. This pest causes damage in agricultural and landscape settings by attacking plants, mainly reducing leaf surface area. For 35 years, Dr. Klein was a research entomologist at the USDA's Agricultural Research Service lab, specializing in garden insects. ‘Adams,’ ‘Candied Apple,’ and ‘Sugar Tyme’ crabapples were the most resistant to defoliation by gypsy moth, fall cankerworm, and eastern tent caterpillar. However, a range of biological alternatives is being investigated. Organic insect traps for monitoring or trapping insect pests of apples and apple trees available at Ladd Research. The Japanese beetle has become a major pest of crops, lawns, and ornamental plants in Missouri. both formulations demonstrated the ability to significantly reduce Japanese and oriental beetle larval populations in turfgrass compared to untreated controls. It was accidentally introduced into the USA, the Azores and recently to northern Italy. The lure on the trap attracts Japanese beetles into the bag. The general morphology of the reproductive apparatus shows paired testes, each of them having six testicular lobes grouped in threes. ), and 53 cultivars of hybrid tea, floribunda, and grandiflora roses (Rosa spp.) Japanese beetles are his area of expertise. Myth #2: Traps make the problem worse by luring more beetles than they catch. The RESCUE!® Japanese & Oriental Beetle Trap, backed by years of research, slowly releases a natural pheromone over the entire beetle season, while competitors’ traps start with a stronger plume and burn off quickly. The box provides a chart with the number of traps needed to cover various size areas. It’s best to place them next to a non-flowering tree or shrub, such as a pine tree or boxwood, which is not attractive to the beetles. The trap’s zippered bottom allows beetles to be easily discarded if the bag fills up before the season is over. Most of continental Europe, except most of Scandinavia and the Mediterranean areas are suitable; the United Kingdom and Ireland are suitable. Then enjoy a beetle-free garden. To control this invasive pest, many people are interested in using less or no insecticides, and other control options that are safer for home-owners and also compatible with or… Quebec has a very recent history of viticultural entomology as the first artisanal permit for wine making was issued by the Quebec Government in 1985, and the first formal research project about arthropods associated with vineyards was initiated in 1997. The facts: Most attractants lure beetles from no more than 200 yards, says Dr. Klein. In Asia, the Caucasus and the area to the north, eastern central China and the Korean Peninsula, and in Africa the mountains of Morocco and coastal southeastern South Africa are also suitable. The taps, he noted, are being opened with greater frequency and the result has been a slow but ever-increasing homogenizing mixture. Questions about a news article you've read? There is no way you can do this.’ I remember lookin… Questions about your PRWeb account or interested in learning more about our news services? Price: $17.99. Refer to K-State Research and Extension Publication MF3151 – Japanese Beetle, which is available and downloadable on-line. ... Japanese beetle trap. It is a severe agricultural pest included in the EU priority pest list being able to feed on more than 300 plant species and having an important biotic potential. The fact that neither of these were particularly resistant to gypsy moth or cankerworm suggests a different mechanism of resistance for defoliators and skeletonizers. We will then treat technology transfer activities that allowed to translate research results into protection programs. Since then they have slowly and steadily made their way westward. “One way was to treat every lawn in Palisade with a pesticide that would kill them. Japanese beetle adults are brightly coloured with a metallic green thorax and head and coppery bronze wing cases (elytra), oval in shape, and vary from 8 to 11 mm in length, and 5 to 7 mm in width (Figs 1 & 2). Mature sperm are grouped in cysts containing about 256 sperm cells. Dr. Klein offers these tips for using Japanese beetle traps effectively: Myth #3: Pesticides are safe to use on Japanese beetles. in the Piedmont region (Northern Italy) in areas infested by the Japanese beetle Popillia japonica. Traps offer safe and “green” alternatives to chemical sprays targeting these bugs. Managing Japanese Beetles without chemicals ... at the Simcoe Research Station we have found daily removal of beetles to be a relatively effective means of controlling beetles on our research plots up to an acre in size. While Japanese beetle injury varied, cultivars most consistently damaged by beetles were ‘Lenape’, ‘Scarlet Wave’, ‘Dawn Pink’, and ‘Crimson Beauty’. ©Copyright 1997-2015, Vocus PRW Holdings, LLC. Japanese beetle traps are designed for capturing Japanese beetles. Traps are effective in one yard alone, but when neighbors band together and put out traps in their yards, the overall beetle numbers are greatly reduced. Popillia japonica is an invasive scarab beetle native to Japan that in 1916 invaded New Jersey in USA. Feeding preferences of Japanese beetle, Popillia japonica Newman, and southern masked chafer, Cyclocephala lurida Bland, grubs for six common cool-season turfgrasses were evaluated in choice tests in the greenhouse. Overall, the proportion of Japanese beetle adults infected by O. popilliae was much greater in Michigan, Ohio, Tennessee and four states in the northeastern USA compared with sites located west of the Mississippi River (18.6 ± 13.3 % and 0.6 ± 1.2 %, respectively). These data must be interpreted cautiously, because previous research has shown that gypsy moth larvae are attracted to the largest Malus trees in a planting, regardless of cultivar. Management of JB is complex because the adults and grubs cause dif, necessarily preclude problems with the other, control. A Japanese beetle trap is often put in place to prevent them from causing significant defoliation to your greenery. Two liquid formulations containing Bacillus thuringiensis serovar japonensis strain Buibui toxin were evaluated in the field for control of Japanese and oriental beetle larvae. are attracted to a wide array of plants, regardless of their acceptability as hosts. Options range from pesticides to picking them off by hand. Of four diets tested, one based on lima beans and casein was selected as the best and easiest for rearing third instars of Japanse beetles, Popillia japonica Newman. Additionally, we show that this difference in behavior is induced by the environmental conditions experienced by the beetles during their non-dispersive larval stages. Trees with the same root ball size dipped in the high rate of Dursban® exhibited smaller leaves in 3 of the 5 trees. Twenty-two cultivars of canna lilies, Canna × generalis, were evaluated for potential resistance to the lesser canna lily leafroller, Geshna cannalis, and the Japanese beetle, Popillia japonica. This article is protected by copyright. Relative resistance to defoliation by Japanese beetles (Popillia japonica Newman) was compared among 28 cultivars of flowering crabapples (Malus spp. For research purposes, a mass trapping design that consisted of an aluminum mesh sock 4 feet long by … Pseudaletia sequax Franclemont was the third species found on the silk. The Japanese beetle, Popillia japonica Newman, an introduced scarab, has become the most widespread and destructive insect pest of turf, landscapes, and nursery crops in the eastern United States. All lindens were severely damaged in years with heavy beetle flight, but Tilia americana ‘Legend’ and T. tomentosa ‘Sterling’ were less damaged than the others in years with moderate beetle pressure. Forty-one plant essential oils were tested under field conditions for the ability to reduce the attraction of adult Japanese beetles, Popillia japonica Newman (Coleoptera: Scarabaeidae), to attractant-baited or nonbaited traps. The all-in-one design, welded construction and capacity for holding a large number of beetles make it ideal for home gardens. Agricultural Experiment Station, Lexington. A morphological comparison with related species is provided. The lures draw in beetles from a 5,000 square feet area. (PRWEB) ... During routine inspections, conducted in 1916, in plant nurseries near Riverton, New Jersey, United States, this insect was observed and reported (DICKERSON;WEISS, 1918;FLEMING, 1976). Don’t place the traps next to ornamental plants. especially carbaryl (144). In the United States the beetle found large areas of turf essential to development during its immature stages, a favorable climate with sufficient rainfall to prevent soil-inhabitants from desiccating and at least 350 plant species to act as hosts for adult beetles. Vocus, PRWeb, and Publicity Wire are trademarks or registered trademarks of Vocus, Inc. or Vocus PRW Holdings, LLC. Annual review of entomology on JB 2002.pdf, All content in this area was uploaded by David Held on May 23, 2014, Nutritional Ecology and Determinants of Host Range, Sampling, Spatial Distribution, Damage Thresholds. Barrows & Gordh (14), who described courtship, copulatory, in offspring, rather than depletion of sperm reserv, lures (45), this blend was identified and refined by. Mortality rates of up to 100% were achieved for adult beetles within a period of 7 dpi only, whereas mortality rates of larvae were between 50 and 100% after 42 dpi. It was also affected by the intra and interespecific competition, by the plant phenological stage and probably by factors related to the local. Japanese beetle traps are most effective for controlling large numbers of beetles. The facts: Insecticides work on adult beetles, but they also kill beneficial pollinators, like bees. WRONG! Hence, accidental or forced ovipositioning in the alternative habitat may induce both an increased performance and preference to the natal habitat type. Utah is only one of 12 states that are considered noninfested by the beetle and takes an aggressive posture when it comes to quarantining nursery and other products from outside its borders. Steinernema feltiae has been found associated mainly with closed habitats such as coniferous and deciduous woodland, characterized by sandy loam-texture and extremely acidic soil. A microsporidian, cytes and tracheal epithelial cells of adults (66). During sperm maturation two C-shaped structures appear in the cytoplasm from the opposite sides of the nucleus that then disappear in late spermatids. Green Earth Japanese Beetle Trap. The virulence of all EPN natural strains was evaluated by laboratory assays against P. japonica third-instar larvae collected during two different periods of the year (spring, autumn). Tanglefoot Japanese Beetle Traps are proven products which are used by homeowners, … Adult Japanese beetles breed and attack between June through August and it is best to stay guarded before that happens. Adults feed on leaves, flowers and fruits of many cultivated plants while larvae mostly damage turf and pastures. induced volatiles, attracting additional JB (123). Therefore, we can conclude that the adults should not be considered as primary pests of apple fruits; however, they may act as secondary pests if the endocarp of the fruits is exposed by some other agent. Both rates of Dursban® provided 100% control of Japanese beetle grubs in all three root ball sizes. Japanese beetle grubs are widely controlled with preventive soil insecticides, but options for remedial control of adults and larvae presently are limited. Japanese beetles love roses, grapes, lindens, sassafras, Japanese maple, and purple-leaf plums, so these plants should be avoided if Japanese beetle … Local gardener Marsha D. brought this to our attention after she decided to do some research when she noticed a large number of dead beetles under her geraniums. ‘Maudie Malcolm’ and ‘Striped Beauty’ were similarly avoided by Japanese beetles, while ‘Journey's End’ sustained moderate injury from this pest. In fact, 2017 was the year when the highest populations were recorded thus far. Meanwhile, some invasive species that recently arrived in Quebec are causing concerns because they are threatening the sustainability of pest management programs. Steinernema carpocapsae was the most abundant and it was mainly distributed in open habitats, such as perennial meadows, uncultivated soils, and cropland, characterized by sandy loam soil texture and acidic pH. Experimental analyses showed that either sex tethered on a leaf attracted males, resulting in their accumulation. CURRENT work on syrphid predators of aphids has demonstrated some behavioural responses of the ovipositing adult females which may be significant in relation to a general understanding of natural enemy action and also to the better use of natural enemies in the control of insect pests. attract ovipositing female beetles and destroying the trees before larvae complete development, and (iii) applying a highly effective systemic insecticide. While Japanese beetles are universally despised, opinions differ on the best way to battle them. It uses the beetle’s natural sex attractant as a lure and does not have harmful chemicals in it. Like other pheromone insect traps, Japanese beetle traps work best as a survey tool. This article discusses current spotted wing drosphila and Japanese beetle trap counts for Minnesota locations, and gives an update on research for management of Japanese beetles. The entomopathogenicity of the isolated nematode was tested on larvae of the model organism Galleria mellonella L. (Lepidoptera Pyralidae). Harrison reached out to CSU researchers, agriculture officials, master gardeners and other farmers. Grubs did not discriminate between tall fescue, Festuca arundinacea Schreb., infected with the endophyte Acremonium coenophialum Morgan-Jones & Gams and endophyte-free tall fescue. Popillia japonica was not able to injure the surface of intact fruits, which means that it is not a primary pest for apple fruits. had no effect on density or mean weight of JB grubs in tall fescue (36, hemocoel, causing fat body depletion (164) and fatal bacteremia. Apparently, it was introduced with some Japanese iris bulbs before the Plant Pest Act of 1912 which required inspection of incoming plant materials. Adaptation to a previously unoccupied niche within a single population is one of the most contentious topics in evolutionary biology as it assumes the simultaneous evolution of ecologically selected and preference traits. This leaves behind the distinctive skeletonized leaves and an overall brown cast in place of lush green vegetation. While mortality correlated with dosage, sporulation on infected cadavers did not. Photo: Annie Klodd. The grubs found within the root balls were primarily oriental beetle, Exomala orientalis (Waterhouse), European chafer, Rhizotrogus majalis (Razoumowsky), Asiatic garden beetle, Maladera castanea (Arrow), northern masked chafer, Cyclocephala borealis Arrow and Japanese beetle. Nucleotide sequences of the gene encoding a small subunit of nuclear ribosomal RNA (ssrDNA), obtained from GenBank for O. popilliae was used to develop a highly specific qPCR test for O. popilliae DNA. Species of Coleoptera and Diptera, considered as secondary pests were common on the tip of the ears. The objective of this research is to obtain a better understanding of the distribution of O. popilliae in North America. in multi-year field evaluations in central Kentucky. “Nine out of 10 homeowners who use a bag trap are satisfied with the results. Observations of the feces of the beetles suggest a potential physiological response due the change of food from soybean leaves to apple fruits. The deferent ducts and accessory glands fuse together into an ejaculatory duct before entering the aedeagus. While all plants sustained at least some injury, cultivars that consistently had the least amount of damage by leafrollers were ‘Maudie Malcolm’, ‘Striped Beauty’, and ‘Journey's End’. Native from Asia, the japanese beetle (Popillia japonica-Scarabeidae) was accidentally introduced in the United States in 1916, The emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), is a devastating, invasive insect pest of ash trees, Fraxinus spp., in North America. According to the model, in North America the beetle has the potential to spread west to the middle of Nebraska, Kansas, Oklahoma and Texas, south to the middle of South Carolina and Georgia and most of Mississippi and Alabama; it has already reached some of these limits. In simulations in which management options were applied only within a 300 m radius from the origin of the infestation, insecticide applications reduced the radial spread by 30% and larval consumption of ash phloem by 40% beyond the treated area. The fall armyworm, Spodoptera frugiperda (J. E. Smith) and the corn earworm, Helicoverpa zea. Dr. Klein says the myths about Japanese beetle traps are misconceptions and offers three “myth busters” to help gardeners win the battle against beetles: Myth #1: Traps lure Japanese beetles from miles around. Most of the samples contained only steinermatids (92.3%), 5.1% contained heterorhabditids, and one sample (2.6%) contained both genera. Follow RESCUE!® on Facebook and Twitter. The objectives were to determine the ability of P. japonica to injury fruits of SweeTango variety apples and the suitability of apple fruits as a food source for this beetle. In the Southern Hemisphere, the southeastern highlands of Australia, Tasmania, New Zealand and the Rio de la Plata area between Argentina and Uruguay and parts of coastal Chile are suitable. The facts: This is the biggest misconception in beetle history. All rights reserved. plants (181). The traps only lure beetles that are already near the yard. Twenty-four cultivars of Malus spp. Studies conducted in 1996, 1998 and 1999 show that immersion of root balls in Dursban® (chlorpyrifos) significantly reduces the number of white grubs, particularly Japanese beetle, Popillia japonica Newman, in B&B (ball and burlap) nursery stock.
