测定了棉铃虫对萎蔫的枫杨 (Pterocaryastenoptera)、加拿大杨 (Populuscanadensis)、黑杨 (P .nigra)和香椿 (Toonasinensis)叶气味的触角电位反应 .结果表明 ,几种植物的气味均能引起棉铃虫雌雄蛾显著的反应 ,雌蛾在交配前后对枫杨、黑杨叶气味的反应无显著差异 .在光周期光照 (L) :黑暗 (D) =14:10条件下 ,进入暗期 7h前后 ,处女雌蛾对萎蔫枫杨和黑杨叶气味的触角电位反应达到高峰 .文中还讨论了杨树枝把引诱棉铃虫的原因 The responses of cotton bollworm to the odor of the leaves of the wilt Pterocaryastenoptera, Populus canadensis, P. nigra and Toonasinensis were determined.The results showed that the odors of several plants all induced the bollworm The response of male and female moths to male and female moths showed no significant difference in the responses of the male and female poplar leaves before and after mating in the period of dark period (D) = 14: 10, , Virgin female moths reached the peak of the tentacles potential responses to the odor of the wilting maple and the black poplar leaves.This paper also discussed the reasons why the poplar branches induced the bollworm
