Heliothis virescens (F.) females responded positively via upwind flight in laboratory assays to volatiles emitted from methylńe chloride washes of fresh whole leaves of host plants including cotton, tobacco, and a weed species,Desmodium tortuosum (Swartz) de Candolle. Except forD. tortuosum, the response increased positively with dose; the steepest slope occurred with an extract of cotton squares (flower buds). Almost all of the moths that landed on the extract dispenser also oviposited. Moths simulated by extracts from cotton squares exhibited a full array of behaviors (upwind flight, contact with the dispenser, examination of the cloth substrate with antennae, and oviposition) expected of gravid individuals seeking sites to propagate the species.
棉铃虫（F.）雌性通过顺风飞行对来自于宿主植物包括棉花、烟草和杂草德斯蒙德草（Swartz）的全叶氯仿提取物做出积极响应。除了德斯蒙德草外，这种反应随剂量的增加而呈正相关；棉花方提取物的斜率最大（花蕾）。几乎所有降落在提取物分配器上的飞蛾也产卵。从棉花方提取物模拟的飞蛾表现出寻找繁殖种群地点的预期的各种行为（顺风飞行、与分配器接触、用触角检查布质基底和产卵）。
