phenology of brown marmorated stink bug described using female reproductive development.temperature-based degree-day models describe insect seasonality and to predict key phenological events. we expand on the use of a temperature-based process defining timing of reproduction through the incorporation of female reproductive physiology for the invasive pentatomid species halyomorpha halys, the brown marmorated stink bug. a five-stage ranking system based on ovary development was able to distinguish between the reproductive statuses of field-collected females. application of this rank ...201728904750
irradiation biology of male brown marmorated stink bugs: is there scope for the sterile insect technique?brown marmorated stink bugs, halyomorpha halys stål (hemiptera: pentatomidae), are regularly intercepted, but there are few eradication tools. currently, no sterile insect technique program exists for hemiptera.201728978259
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 ...201728984006
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 ...201829068708
climate change impacts on the potential distribution and abundance of the brown marmorated stink bug (hemiptera: pentatomidae) with special reference to north america and europe.the invasive brown marmorated stink bug, halyomorpha halys (stål; hemiptera: pentatomidae), has recently emerged as a harmful pest of horticultural crops in north america and europe. native to east asia, this highly polyphagous insect is spreading rapidly worldwide. climate change will add further complications to managing this species in terms of both geographic distribution and population growth. this study used climex to compare potential h. halys distribution under recent and future climate ...201729069361
establishment of molecular genetic approaches to study gene expression and function in an invasive hemipteran, halyomorpha halys.hemiptera is a large clade of insects understudied in terms of developmental biology. halyomorpha halys, the brown marmorated stink bug (bmsb, referred to throughout as h. halys), is an invasive hemipteran pest of the mid-atlantic region of the usa that has rapidly spread to other regions in recent years, devastating a wide range of crops using a piercing and sucking mechanism. its phylogenetic position, polyphagous habits, and rapid spread in the usa suggested that h. halys would be an ideal sy ...201729075432
assessment of feeding acceptance and injury of kerman pistachios, pistacia vera, by brown marmorated stink bug (hemiptera: pentatomidae).in the united states, california (ca) is the primary commercial producer of pistachio nuts, pistacia vera l. (anacardiaceae). the brown marmorated stink bug (bmsb), halyomorpha halys (stål) (hemiptera: pentatomidae), an invasive and polyphagous insect pest from asia, has established in urban areas in several pistachio-growing counties in ca. breeding bmsb populations have not been detected in commercial pistachio acreage. however, the detection of bmsb in kern and fresno counties, major kerman p ...201729117381
attraction of halyomorpha halys (hemiptera: pentatomidae) haplotypes in north america and europe to baited traps.halyomorpha halys is a global invasive species, native to southeast asia, that is threatening agriculture in invaded regions. our objectives were to: 1) establish the attractiveness of semiochemical stimuli paired with field-deployed traps in europe (greece, hungary, italy, and switzerland), compared with maryland, usa, and 2) identify h. halys haplotypes recovered from traps at each location. we found qualitatively identical patterns of capture between sites located across europe and in marylan ...201729208930
identification of soybean host plant resistance to brown marmorated stink bugs in maturity group iii plant introductions.halyomorpha halys (stål; hemiptera: pentatomidae), brown marmorated stink bug (bmsb), is a polyphagous nonnative insect first found in the united states in 1996. as of 2017, bmsb has been detected in 43 states and is a severe agricultural pest in mid-atlantic states. on soybean, glycine max (l.) merr (fabales: fabaceae), damage from bmsb infestation ranges from puncture marks with seed discoloration and deformities to seed and pod abortion. host plant resistance has been used for managing pest p ...201729220502
enhanced response of halyomorpha halys (hemiptera: pentatomidae) to its aggregation pheromone with ethyl decatrienoate.the invasive stink bug species, halyomorpha halys (stål) (hemiptera; pentatomidae), severely damages multiple agricultural commodities, resulting in the disruption of established ipm programs. several semiochemicals have been identified to attract h. halys to traps and monitor their presence, abundance, and seasonal activity. in particular, the two-component aggregation pheromone of h. halys, (3s,6s,7r,10s)-10,11-epoxy-1-bisabolen-3-ol and (3r,6s,7r,10s)-10,11-epoxy-1-bisabolen-3-ol (pher), in c ...201729272430
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.201829296555
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 ...201829342183
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 ...201829347977
