Brown marmorated stink bug, Halyomorpha halys Stål, is an invasive, herbivorous insect species that was accidentally introduced to the United States from Asia. First discovered in Allentown, PA, 1996, H. has now been reported at least 40 states States. Additional invasions have detected Canada, Switzerland, France, Germany, Italy, and Lichtenstein, suggesting this invasive could emerge as a cosmopolitan pest species. In its native range, classified outbreak pest; however, North America,...
Significance Area-wide Bacillus thuringiensis (Bt) adoption suppresses pests regionally, with declines expanding beyond the planted Bt crops into other non-Bt crop fields. The offsite benefits to vegetable from such pest suppression have not been documented. We show that widespread field corn is strongly associated marked decreases in number of recommended insecticidal applications, insecticides applied, and damage United States. These positive impacts growers, including organic producers,...
A recent identification of the two-component aggregation pheromone invasive stink bug species, Halyomorpha halys (Stål), in association with a synergist, has greatly improved ability to accurately monitor seasonal abundance and distribution this destructive pest. We evaluated attraction H. black pyramid traps baited lures containing alone, synergist methyl (2 E ,4 ,6 Z )-decatrienoate (MDT) two combination. Traps were deployed around areas agricultural production including fruit orchards,...

The brown marmorated stink bug, Halyomorpha halys (Stål) is an invasive insect in the Mid-Atlantic region that spreading rapidly across United States. In this article, authors document pest potential of bug to vegetable crops based on their observations States thus far. Accepted for publication 20 April 2012. Published 23 May
Abstract Hemp (Cannabis sativa L.) is now being grown within the United States over a much broader geographic area and for different uses than during its last period of significant production that ended after World War II. Within past 3 yr, large number arthropod species have been documented to feed on hemp in States. Among key pest species, corn earworm, Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), has demonstrated greatest potential crop injury, particularly damaging flower buds....
Reliable monitoring of the invasive Halyomorpha halys abundance, phenology and geographic distribution is critical for its management. adult nymphal captures on clear sticky traps in black pyramid were compared 18 states across Great Lakes, Mid-Atlantic, Southeast, Pacific Northwest Western regions United States. Traps baited with commercial lures containing H. pheromone synergist, deployed at field sites bordering agricultural or urban locations host plants. Nymphal greater than those...
Transgenic corn and cotton that produce Cry Vip3Aa toxins derived from Bacillus thuringiensis (Bt) are widely planted in the United States to control lepidopteran pests. The sustainability of these Bt crops is threatened because earworm/bollworm, Helicoverpa zea (Boddie), evolving a resistance toxins. Using sweet as sentinel plant monitor evolution resistance, collaborators established 146 trials twenty-five states five Canadian provinces during 2020–2022. study evaluated overall changes...
Stink bugs (Hemiptera: Pentatomidae) cause significant damage to many different crops and horticultural commodities in Virginia. However, little is known about the species diversity or impact of stink bug egg parasitoids state. A survey was conducted 2005 2006 (May through September) wheat (Triticum aestivum L.), soybean (Glycine max several vegetable by collecting natural masses various monitoring sentinel masses. total 570 Euschistus servus (Say) eggs 26 masses, 11,197 Murgantia...
Cereal leaf beetle, Oulema melanopus L., is an introduced insect pest of small grains first recorded in the United States early 1960s. Since its introduction from Europe or Asia into Michigan, cereal beetle has rapidly spread and can now be found most states. feeds on numerous species grasses considered a major oats, barley, wheat. Although several studies have investigated biology population dynamics, gaps remain understanding mechanisms that influence distribution, which makes predicting...
The brown marmorated stink bug, Halyomorpha halys (Stål), is native to eastern Asia and presently invading North America. Little known about the exposure effects of winter temperatures in newly invaded regions on H. . overwintering habitats that this species utilizes vary greatly their thermal buffering capacity. They naturally overwinter aggregations beneath loose bark trees cliff outcroppings, but will also commonly aggregate buildings. Effects cold such as mortality freezing have yet be...
Diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), has become the most destructive insect pest of cruciferous vegetables ( Brassica oleracea L.) worldwide, and is a continuing problem especially in southern United States. Because inconsistencies individual control methods, inefficiencies time demands scouting, lack clear thresholds, current management practices emphasize prophylactic use insecticides. Numerous other methods are available for P. including host plant...
The squash bug, Anasa tristis (DeGeer), is an endemic species of the Americas that feeds on plants in family Cucurbitaceae. pest particularly abundant and damaging genus Cucurbita (i.e., zucchini, summer squash, pumpkins). Squash bug has become problematic recent years due to changes insecticide use strategies by conventional growers, dramatic increases organic vegetable production, increasing incidences cucurbit yellow vine disease, a phloem-clogging bacterial disease transmitted bug. A...
Long-lasting insecticide nets (LLINs), which have incorporated within the fibers, been widely used for control of malaria and other insect-vectored diseases. Only recently researchers begun exploring their use agricultural pests. In this study, we evaluated toxicity a deltamethrin-incorporated LLIN, ZeroFly (Vestergaard-Frandsen, Washington, DC) brown marmorated stink bug, Halyomorpha halys (Stål). lab, exposure to net 10 s resulted in >90% mortality H. nymphs >40% adults. Longer higher...
Significance Many insects release volatile terpenes for chemical communication. However, the biosynthetic origin and evolution of these infochemicals are mostly unknown. We show that harlequin bug, Murgantia histrionica , a stink bug pest (Hemiptera) crucifer crops, produces terpene aggregation pheromone by an enzyme is unrelated to microbial plant synthases. M. synthase activity highly sex- tissue-specific makes sesquiterpene alcohol, so far unknown in animals, as precursor. The evolved...
Abstract As part of an insect resistance management plan to preserve Bt transgenic technology, annual monitoring target pests is mandated detect susceptibility changes toxins. Currently Helicoverpa zea (Boddie) involves investigating unexpected injury in crop fields and collecting larvae from non-Bt host plants for laboratory diet bioassays determine mortality responses diagnostic concentrations To date, this approach has not detected any significant change the known range baseline toxins,...
Mealybugs (Hemiptera: Pseudococcidae) are one of the prevalent pests infesting wine grapes in eastern United States. Their close association with ants (Hymenoptera: Formicidae) provides them protection against natural enemies. In this paper, we present our research on identification mealybug species and ant genera around vineyard effect use sugar dispensers populations fruit cluster infestations. Field trials were carried out two commercial vineyards Virginia, States, a history The without...
Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) is an invasive pest of numerous agricultural crops with increasing global distribution. Finding simple and reliable monitoring tools for H. surveillance programs imperative. In 2016, we compared standard pyramid traps to clear sticky cards attached atop wooden stakes evaluated two commercially formulated lures (Trécé AgBio) low high rates the aggregation pheromone (PHER) synergist (MDT) at 12 sites (low: 5 mg PHER + 50...
Neonicotinoid insecticides have been the most common management tool for Colorado potato beetle, Leptinotarsa decemlineata (Say), infestations in cultivated nearly 20 yr. The relative ease of applying neonicotinoids at planting coupled with inexpensive, generic neonicotinoid formulations has reduced incentive growers to transition from these products other mode action (MoA) groups early-season L. control. Continuous use resulted resistant populations some production areas eastern United...
