Stink bugs (Pentatomidae) produce volatile chemical substances in the scent glands, with unpleasant odors that function as alarm and defense signals against natural enemies. The contents of the scent glands of the predatory Podisus nigrispinus and its prey, the phytophagous Euschistus heros were used to evaluate the behavioral interactions between these two insects. Quantitative and qualitative analyses of odor components were performed by gas chromatography (GC/FID and GC/MS) and behavioral response evaluated by video-tracking system. The chemical composition of the odor produced by P. nigrispinus and E. heros contains aldehydes and hydrocarbons. The chemical mixture has quantitative and qualitative component differences between species and sexes, with 20 compounds identified for P. nigrispinus and 17 compounds for E. heros. The compounds (E)-2-hexenal, hexenoic acid, (E)-2-decenal, tridecane, tetradecane, and pentadecane occur in both species, but with different amounts between males and females. The secretion of the scent gland of P. nigrispinus and E. heros produces repellent and irritant effects between species and between sexes of the same species, supporting the defensive function of these compounds. Chemical identification of the Pentatomidae scent gland compounds may influence in insect behavior cause side effects in other insects. Overall, these compounds can be a sustainable and novel source of insecticides with potential to agricultural pest control.

臭虫（Pentatomidae）在气味腺中产生挥发性化学物质，带有难闻的气味，可作为对天敌的警报和防御信号。利用捕食性黑dis（Podisus nigrispinus）及其猎物的植物性食管性（Euschistus）英雄的气味腺的内容来评估这两种昆虫之间的行为相互作用。通过气相色谱（GC / FID和GC / MS）进行气味成分的定量和定性分析，并通过视频跟踪系统评估行为反应。P. nigrispinus和E. heros产生的气味的化学成分包含醛和碳氢化合物。该化学混合物在物种和性别之间具有定量和定性的成分差异，其中有20种化合物被鉴定为黑粉虱，而17种化合物则被鉴定为英雄。化合物（E）-2-己烯，己烯酸，（E）-2-癸烯，十三烷，十四烷和十五烷都存在于两种物种中，但雄性和雌性的含量不同。P. nigrispinus和E. heros的气味腺的分泌在物种之间以及同一物种的性别之间产生驱避和刺激作用，从而支持这些化合物的防御功能。蝇科气味腺化合物的化学鉴定可能会影响昆虫的行为，并引起其他昆虫的副作用。总体而言，这些化合物可以成为可持续的新型杀虫剂来源，对控制农业有害生物具有潜在的意义。
