在飞行隧道生物测定中，交配的雌性Heliothis subflexa（Gn.）飞蛾在双重选择试验中表现出对来自其唯一已知宿主酸浆属的提取物的挥发物的显著偏好。（groundcherry）.然而，H. virescens（F.），一个多食性的物种，积极响应的趋风性，从敏感的烟草，棉花，Desmodiumtortuosum（寄主植物），和地面樱桃，非寄主提取物。virescensfemales没有飞到从抗性烟草栽培品种的提取物散发的挥发物。
In flight-tunnel bioassays, mated femaleHeliothis subflexa(Gn.) moths demonstrated in dual-choice tests a significant preference for volatiles from an extract of their only known host,Physalisspp. (groundcherry). However,H. virescens(F.), a polyphagous species, responded positively by anemotaxis to extracts from susceptible tobacco, cotton,Desmodium tortuosum(host plants), and groundcherry, a nonhost.H. virescensfemales did not fly to volatiles emanating from an extract of a resistant tobacco cultivar.
