| field trapping of the invasive brown marmorated stink bug, halyomorpha halys, with geometric isomers of methyl 2,4,6-decatrienoate. | the brown marmorated stink bug, halyomorpha halys (stål), is a polyphagous pest indigenous to northeastern asia where it damages various trees, vegetables, and leguminous crops. the bug was recently introduced into the u.s. and could potentially become a pest. in its native range, h. halys was reportedly attracted to the aggregation pheromone of the brown-winged green bug, plautia stali, methyl (2 e,4 e,6 z)-decatrienoate. we also observed that traps baited with this compound are attractive to h ... | 2008 | 18069789 |
| the crypt-dwelling primary bacterial symbiont of the polyphagous pentatomid pest halyomorpha halys (hemiptera: pentatomidae). | a recent invader of north america, the brown marmorated stink bug (halyomorpha halys stål) is a polyphagous pentatomid that harbors a gammaproteobacterial mutualist in the crypts of specialized midgut gastric caeca (region v4). histological analyses revealed a single rod-shaped morphology abundant in distal v4 midgut caecal crypts. a strong fluorescence signal was detected when thin sections of these tissues were hybridized with a fluorescently-labeled, enterobacteriaceae-specific oligonucleotid ... | 2014 | 24874153 |
| 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 |
| discovery of the aggregation pheromone of the brown marmorated stink bug (halyomorpha halys) through the creation of stereoisomeric libraries of 1-bisabolen-3-ols. | we describe a novel and straightforward route to all stereoisomers of 1,10-bisaboladien-3-ol and 10,11-epoxy-1-bisabolen-3-ol via the rhodium-catalyzed asymmetric addition of trimethylaluminum to diastereomeric mixtures of cyclohex-2-enones 1 and 2. the detailed stereoisomeric structures of many natural sesquiterpenes with the bisabolane skeleton were previously unknown because of the absence of stereoselective syntheses of individual stereoisomers. several of the bisabolenols are pheromones of ... | 2014 | 24963992 |
| first record of the brown marmorated stink bug, halyomorpha halys (hemiptera: heteroptera: pentatomidae), in hungary, with description of the genitalia of both sexes. | the brown marmorated stink bug, halyomorpha halys (stål, 1855) (hemiptera: heteroptera: pentatomidae) is recorded for the first time from hungary. the circumstances of finding this species and a detailed description of both male and female genitalia are given. the currently known distribution, biology and significance of the species are briefly reviewed. | 2014 | 24871833 |
| characterization of overwintering sites of the invasive brown marmorated stink bug in natural landscapes using human surveyors and detector canines. | halyomorpha halys is an invasive species from asia causing major economic losses in agricultural production in the mid-atlantic region of the united states. unlike other crop pests, h. halys is also well-known for nuisance problems in urban, suburban, and rural areas, as massive numbers of adults often invade human-made structures to overwinter inside protected environments. research efforts have focused on populations in human-made structures while overwintering ecology of h. halys in natural l ... | 2014 | 24717734 |
| insights into the saliva of the brown marmorated stink bug halyomorpha halys (hemiptera: pentatomidae). | we examined the salivary gland structure of the brown marmorated stink bug (pentatomidae: halyomorpha halys) and developed methods for independent collection of watery saliva and sheath saliva. this stink bug has become a serious invasive pest of agriculture in the united states and its saliva is largely responsible for the damage it causes. we determined by protein gel analysis and shotgun proteomics that the suite of proteins comprising the sheath and watery saliva are very distinct. our resul ... | 2014 | 24586332 |
| an exotic parasitoid provides an invasional lifeline for native parasitoids. | the introduction of an exotic species may alter food webs within the ecosystem and significantly affect the biodiversity of indigenous species at different trophic levels. it has been postulated that recent introduction of the brown marmorated stinkbug (halyomorpha halys (stål)) represents an evolutionary trap for native parasitoids, as they accept h. halys egg masses as a host but produce no viable progeny. interspecific interactions between european egg parasitoid, trissolcus cultratus (mayr), ... | 2017 | 28070291 |
| effectiveness of glues for harmonic radar tag attachment on halyomorpha halys (hemiptera: pentatomidae) and their impact on adult survivorship and mobility. | we evaluated the effectiveness of three cyanoacrylate glues (trade names: krazy [elmer's products inc., westerville, oh], loctite [henkel corporation, rocky hill, ct], and fsa [barnes distribution, cleveland, oh]) to attach harmonic radar tags securely on adult halyomorpha halys (stål) (hemiptera: pentatomidae) and quantified the effect of the radar tag attachment on insect survivorship and mobility. in the laboratory, the strength of the glue bond between the radar tag and h. halys pronotum was ... | 2013 | 23726060 |
| impact of insecticide residue exposure on the invasive pest, halyomorpha halys (hemiptera: pentatomidae): analysis of adult mobility. | twenty eight insecticides were evaluated in the laboratory to characterize the impact of specific compounds on locomotory behavior and mobility of adult halyomorpha halys (stål) (hemiptera: pentatomidae). horizontal distance and angular velocity were measured for individuals exposed to dry insecticide residue for 4.5 h to evaluate how quickly and intensely a given insecticide induced changes in motor activities in no-choice glass arenas. eight out of nine pyrethroid insecticides induced uncoordi ... | 2013 | 23448027 |
| 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 |
| 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 ... | 2017 | 29208930 |
| impact of insecticides on the invasive halyomorpha halys (hemiptera: pentatomidae): analysis of insecticide lethality. | the efficacy of 37 insecticide treatments against adult halyomorpha halys (stål) was established based on exposure to 18-h old dry insecticide residue in laboratory bioassays. individual adult h. halys were exposed to an insecticide residue for 4.5 h and then monitored daily for survivorship over a 7-d period. the proportion of dead and moribund insects was used as an estimate of overall insecticide efficacy against h. halys immediately after the exposure period and over the 7-d trial. among all ... | 2012 | 23156170 |
