deltamethrin-incorporated nets as an integrated pest management tool for the invasive halyomorpha halys (hemiptera: pentatomidae).	long-lasting insecticide nets (llins), which have insecticide incorporated within the fibers, have been widely used for control of malaria and other insect-vectored diseases. only recently have researchers begun exploring their use for control of agricultural pests. in this study, we evaluated the toxicity of a deltamethrin-incorporated llin, zerofly (vestergaard-frandsen, washington, dc) for control of the brown marmorated stink bug, halyomorpha halys (stål). in the lab, exposure to the zerofly ...	2017	28334163
landscape factors influencing stink bug injury in mid-atlantic tomato fields.	landscape structure and diversity influence insect species abundance. in agricultural systems, adjacent crop and non-crop habitats can influence pest species population dynamics and intensify economic damage. to investigate the influence of landscape factors on stink bug damage in agricultural systems, we assessed stink bug damage from 30 processing tomato fields in the mid-atlantic united states and analyzed landscape structure and geographic location. we found that forest shape and size, and g ...	2017	28204617
double strand rna delivery system for plant-sap-feeding insects.	double-stranded rna (dsrna)-mediated gene silencing, also known as rna interference (rnai), has been a breakthrough technology for functional genomic studies and represents a potential tool for the management of insect pests. since the inception of rnai numerous studies documented successful introduction of exogenously synthesized dsrna or sirna into an organism triggering highly efficient gene silencing through the degradation of endogenous rna homologous to the presented sirna. managing hemipt ...	2017	28182760
influence of winemaking processing steps on the amounts of (e)-2-decenal and tridecane as off-odorants caused by brown marmorated stink bug (halyomorpha halys).	brown marmorated stink bugs (bmsb) release stress compounds, tridecane and (e)-2-decenal, that affect final wine quality. this study focuses on determining the effect of wine processing on (e)-2-decenal and tridecane release in both red and white wines. wines were produced by adding live bmsb to grape clusters at densities of 0, 0.3, 1, and 3 bugs/cluster. compound concentrations were measured using headspace solid phase microextraction with multidimensional gas chromatography and mass spectrome ...	2017	28064492
a laboratory evaluation of chemigation to manage stink bugs (hemiptera: pentatomidae).	application of insecticides for stink bug management through overhead irrigation, also called chemigation, could reduce application costs, soil compaction, and applicator exposure, while enabling growers to treat multiple fields simultaneously. the objective of these laboratory experiments was to compare knockdown, survival, and efficacy of insecticides when appropriately diluted for ground sprayer and chemigation applications. treatments included water, bifenthrin [0.11 kg (ai)/ha] and dicrotop ...	2017	28334122
nosema maddoxi sp. nov. (microsporidia, nosematidae), a widespread pathogen of the green stink bug chinavia hilaris (say) and the brown marmorated stink bug halyomorpha halys (stål).	we describe a unique microsporidian species that infects the green stink bug, chinavia hilaris; the brown marmorated stink bug, halyomorpha halys; the brown stink bug, euschistus servus; and the dusky stink bug, euschistus tristigmus. all life stages are unikaryotic, but analysis of the consensus small subunit region of the ribosomal gene places this microsporidium in the genus nosema, which historically has been characterized by diplokaryotic life stages. it is also characterized by having the ...	2017	28984006
seasonal parasitism and host specificity of trissolcus japonicus in northern china.	the brown marmorated stink bug, halyomorpha halys (stål), native to china, japan, and korea, has emerged as a harmful invasive pest of a variety of crops in north america and europe. the asian egg parasitoid trissolcus japonicus has been identified as the most promising agent for classical biological control of invasive h. halys populations. a 4-year study evaluated the fundamental and ecological host ranges of t. japonicus as well as its phenology and impact on h. halys populations in fruit orc ...	2017	28824354
a floral fragrance, methyl benzoate, is an efficient green pesticide.	over-reliance on synthetic pesticides in insect pest control has caused widespread public and scientific concerns for human health and the environment, especially since many insect pests have already developed resistances to conventional pesticides and bt products. for this reason, there is a considerable interest in development of alternative control methods for insect pest management. based on laboratory studies, we report that methyl benzoate (mb), a naturally-occurring compound in many plant ...	2017	28181532
an invasive insect herbivore disrupts plant volatile-mediated tritrophic signalling.	plants respond to insect attack by emission of volatile organic compounds, which recruit natural enemies of the attacking herbivore, constituting an indirect plant defence strategy. in this context, the egg parasitoid trissolcus basalis is attracted by oviposition-induced plant volatiles emitted by vicia faba plants as a consequence of feeding and oviposition by the pentatomid host nezara viridula. however, this local tritrophic web could be affected by the recent invasion by the alien pentatomi ...	2017	28824353
expansion of cytochrome p450 and cathepsin genes in the generalist herbivore brown marmorated stink bug.	the brown marmorated stink bug (halyomorpha halys) is an invasive pest in north america which causes severe economic losses on tree fruits, ornamentals, vegetables, and field crops. the h. halys is an extreme generalist and this feeding behaviour may have been a major contributor behind its establishment and successful adaptation in invasive habitats of north america. to develop an understanding into the mechanism of h. halys' generalist herbivory, here we specifically focused on genes putativel ...	2018	29347977
identification of volatiles released by diapausing brown marmorated stink bug, halyomorpha halys (hemiptera: pentatomidae).	the brown marmorated stink bug, halyomorpha halys, is an agricultural and urban pest that has become widely established as an invasive species of major concern in the usa and across europe. this species forms large aggregations when entering diapause, and it is often these aggregations that are found by officials conducting inspections of internationally shipped freight. identifying the presence of diapausing aggregations of h. halys using their emissions of volatile organic compounds (vocs) may ...	2018	29342183
irritant contact keratitis caused by the bodily fluids of a brown marmorated stink bug.	the brown marmorated stink bug is native to asia (china, taiwan, japan, and the korean peninsula). its bodily fluids are toxic and irritating to the human skin and eyes. human case reports are rare. only one report of irritant contact dermatitis has been published. we report a case of irritant contact keratitis resulting from the chemical components of the bodily fluids of the bug.	2018	29296555
impact of the invasive brown marmorated stink bug in north america and europe: history, biology, ecology, and management.	the brown marmorated stink bug (bmsb), halyomorpha halys (stål), is an invasive pentatomid introduced from asia into the united states, canada, multiple european countries, and chile. in 2010, bmsb populations in the mid-atlantic united states reached outbreak levels and subsequent feeding severely damaged tree fruit as well as other crops. significant nuisance issues from adults overwintering inside homes were common. bmsb is a highly polyphagous species with a strong dispersal capacity and hig ...	2018	29068708
