Abstract Stink bugs (Hemiptera: Pentatomidae) are commonly monitored using pyramid traps baited with a pheromone. Initially, the pyramid traps were painted yellow and predominantly used to monitor native stink bug species. However, research studies involving the exotic Halyomorpha halys Stål (Hemiptera: Pentatomidae) now use pyramid traps that are black, not yellow. As H. halys moves across the southeastern United States, the use of a single trap, yellow or black, for monitoring and conducting research studies would be beneficial. Our objective was to compare black and yellow pyramid traps baited with a lure to determine if one was superior for trapping herbivorous stink bugs. This study was conducted at four locations, three in Alabama and one in Georgia, over 2 yr. Additionally, residual efficacy of the lure was measured via trap capture over 1-mo intervals. Our results showed that only when native stink bug species were combined, and only in 1 yr, were captures significantly affected by trap color. Capture of the exotic H. halys and the most abundant native species, Euschistus servus (Say), was not significantly affected by trap color. Trap capture was significantly affected by how long a lure was in a trap. The data from this study suggests that when traps are used in conjunction with a pheromone to monitor multiple species of adult stink bugs, especially native species, the yellow pyramid trap is favored.

Chemosensory proteins (CSPs) have been identified in the sensory tissues of various insect species and are believed to be involved in chemical communication in insects. However, the physiological roles of CSPs in Halyomorpha halys, a highly invasive insect species, are rarely reported. Here, we focused on one of the antennal CSPs (HhalCSP15) and determined whether it was involved in olfactory perception. Reverse transcription PCR (RT-PCR) and quantitative real-time PCR (qRT-PCR) analysis showed that HhalCSP15 was enriched in nymph and male and female adult antennae, indicating its possible involvement in the chemosensory process. Fluorescence competitive binding assays revealed that three of 43 natural compounds showed binding abilities with HhalCSP15, including β-ionone (Ki=11.9±0.6μM), cis-3-hexen-1-yl benzoate (Ki=10.5±0.4μM), and methyl (2E,4E,6Z)-decatrienoate (EEZ-MDT; Ki=9.6±0.8μM). Docking analysis supported the experimental affinity for the three ligands. Additionally, the electrophysiological activities of the three ligands were further confirmed using electroantennography (EAG). EEZ-MDT is particularly interesting, as it serves as a kairomone when H. halys forages for host plants. We therefore conclude that HhalCSP15 might be involved in the detection of host-related volatiles. Our data provide a basis for further investigation of the physiological roles of CSPs in H. halys, and extend the olfactory function of CSPs in stink bugs.

Abstract Field release of classical biocontrol agents requires prior risk assessment to ensure that non-target effects are averted. No-choice and choice bioassays can provide basic information on the physiological host range of the candidate agent. However, other experimental methods, like olfactometer bioassays of host-plant complexes, can depict more realistically the likelihood that the released biocontrol agent localizes non-targets in the field. Halyomorpha halys Stål (Hemiptera: Pentatomidae) is native to Asia and invasive in North America and Europe, where it represents a major threat for crops. The Asiatic egg parasitoid Trissolcus mitsukurii (Ashmead) is adventive in Italy and exhibits high parasitization ability on H. halys. In the light of evaluating T. mitsukurii for H. halys biocontrol, its physiological host range has been already partially explored. Here, we investigated the ability of the parasitoid to exploit odours associated with H. halys or with the following non-targets: Arma custos F., Dolycoris baccarum L., Eurydema ventralis Kolenati, and Nezara viridula L. (all Hemiptera: Pentatomidae). Specifically, using a Y-tube olfactometer, we tested the response of parasitoid females to plants bearing naturally laid eggs, to physogastric females or eggs of the different species. We observed that T. mitsukurii is only attracted by plants challenged by eggs of H. halys or N. viridula, while it is not attracted by physogastric females or eggs alone. Remarkably, T. mitsukurii was almost repelled by plants bearing eggs of the beneficial A. custos. Our results usefully contribute to a more valuable assessment of the potential non-target risks in case of parasitoid release.

В практике защиты растений одним из актуальных методов мониторинга насекомых является хеморегуляторный метод, к средствам которого относят феромоны, гормоны, аттрактанты, репелленты и т.д., предназначенные для выявления фитофагов и оценки уровня заселенности ими сельскохозяйственных культур. Цель исследований заключалась в проведении сравнительных испытаний новых и усовершенствованных феромонных ловушек и препаратов для мониторинга доминирующего вредителя винограда - гроздевой листовёртки ( Lobesia botrana Den. et Schiff.) и инвазийного карантинного вида - коричнево-мраморного клопа ( Halyomorpha halys Stаl.) на виноградниках Крыма. Работу проводили в условиях 2020 г. согласно методическим подходам, используемым в отечественной и международной практике энтомологических исследований на промышленных насаждениях основных зон виноградарства Крыма. Установлено, что при средней интенсивности лёта бабочек I генерации гроздевой листовёртки на винограднике сорта Каберне-Совиньон опытные феромонные ловушки типа «Дельта», «Ромб» и «Квадро» производства ФГБУ «ВНИИКР» показали близкие значения уловистости: в среднем 826-1042 экз./ловушку. Наиболее перспективной определена ловушка «Дельта». На фоне средней и низкой интенсивности лёта бабочек I-III генераций гроздевой листовёртки на виноградниках трех зон установлен одинаковый уровень биологической активности четырех феромонных препаратов производства АО «Щелково Агрохим» (разница 0,3-3,1 %) как на фольгапленовых диспенсерах (1,5 мг феромона), так и на трубчатых (0,8-3,0 мг феромона). Показан достаточный уровень эффективности фольгапленовых диспенсеров на протяжении четырех месяцев (снижение биологической активности 4-14 %). На фоне низкой численности коричнево-мраморного клопа на виноградниках установлена более высокая (в 5,2 раза) биологическая активность препарата с феромоном и аттрактантом синтеза АО «Щелково Агрохим» в сравнении с препаратом, содержащем только феромон. Использование этих феромонных препаратов в ловушках барьерного типа позволило впервые выявить новый карантинный вид клопа на участках двух зон виноградарства Крыма. One of the most relevant methods for monitoring insects in the practice of plant protection is the chemoregulatory method, the means of which are pheromones, hormones, attractants, repellents, etc., intended to identify phytophages and assess the level of population density on agricultural crops. The aim of the research was to carry out comparative tests of new and improved pheromone traps and preparations for monitoring the dominant grape pest - European grape moth ( Lobesia botrana Den. Et Schiff.) and the invasive quarantine species - brown marmorated stink bug ( Halyomorpha halys Stаl.) in the vineyards of Crimea. The work was carried out in the conditions of 2020 according to the methodological approaches used in national and international practices of entomological research on industrial plantations of the main viticulture zones of Crimea. It was found that with an average flight intensity of butterflies of European grape moth of the I generation in the vineyard of ‘Cabernet-Sauvignon’ cultivar, experimental pheromone traps of Delta, Romb and Quadro types produced by FSBI VNIIKR showed similar values of catching capacity: at the average rate of 826-1042 nos. / trap. Delta was defined as the most promising trap. Against the background of an average and low flight intensity of European grape moth butterflies of the I-III generations in the vineyards of three zones, similar level of biological activity of four pheromone preparations produced by JSC Shchelkovo Agrokhim (difference - 0.3-3.1%) was established on propylene foil (1, 5 mg of pheromone) and tube dispensers (0.8-3.0 mg of pheromone). A sufficient level of efficiency of propylene foil dispensers was shown during four months (a decrease in biological activity by 4-14%). Against the background of a low number of brown marmorated stink bugs in the vineyards, a higher (5.2 times) biological activity of the preparation with pheromone and attractant of JSC Shchelkovo Agrokhim production in comparison with the preparation containing only pheromone was established. Using of these pheromone preparations in barrier-type traps made it possible to reveal for the first time a new quarantine bug species in the plots of two Crimean viticultural zones.
