Polistes paper wasps in the Fuscopolistes subgenus (Hymenoptera: Vespidae) can be serious pests when they swarm at tall man-made structures. Chemical attractants may be useful to trap such paper wasps when they achieve pest status. Polistes venom has been shown to elicit a variety of behavioral responses in congeneric wasps, making it a source for potential chemical attractants. The compound N-(3-methylbutyl)acetamide is a principal volatile component in the venom of many female vespid wasps, including numerous Polistes species. We report the presence of N-(3-methylbutyl)acetamide in autumn gynes of Polistes metricus Say, Polistes bellicosus Cresson, and Polistes dorsalis (F.), as well as workers of Polistes aurifer (Saussure), P. bellicosus, P. metricus, and P. dorsalis. In field tests conducted in Florida, Georgia, South Carolina, and Washington, N-(3-methylbutyl)acetamide attracted male and female P. aurifer and P. metricus, as well as male P. dorsalis and P. bellicosus. Thus, N-(3-methylbutyl)acetamide may be a useful lure for trapping these paper wasps in pest situations.
褐茎寡鬃实蝇亚属（膜翅目：胡蜂科）中的 Polistes 纸蜂在高大的人造结构上成群结队时可能成为严重的害虫。当它们达到害虫状态时，化学引诱剂可能有助于诱捕这些纸蜂。Polistes 毒液已被证明会引起同种黄蜂的各种行为反应，使其成为潜在化学引诱剂的来源。N-(3-甲基丁基)乙酰胺是许多雌性胡蜂毒液中的主要挥发性成分，包括许多 Polistes 物种。我们报告了 N-(3-甲基丁基)乙酰胺在 Polistes metricus Say、Polistes bellicosus Cresson 和 Polistes dorsalis (F.) 的秋雌蜂以及 Polistes aurifer (Saussure)、P. bellicosus、P. metricus 和 P. dorsalis 的工蜂中的存在。在佛罗里达州、佐治亚州、南卡罗来纳州和华盛顿州进行的野外测试中，N-(3-甲基丁基)乙酰胺吸引了 P. aurifer 和 P. metricus 的雄性和雌性，以及 P. dorsalis 和 P. bellicosus 的雄性。因此，N-(3-甲基丁基)乙酰胺可能是诱捕这些纸蜂在害虫情况下的有用诱饵。
