摘　　要：田间调查表明，烟实夜蛾和棉铃虫混合种群在黄花烟草上的落卵量显著高于红花烟草，其百株卵量是红花烟草上的6～20倍.室内分析了烟草叶片挥发物和叶片浸洗物对2种夜蛾产卵行为的影响，结果表明，黄花烟草叶片粗提物对烟实夜蛾产卵有明显的引诱作用，烟实夜蛾在涂有黄花烟草叶片挥发物或叶片浸洗物纱布上的落卵量是红花烟草上的2～10倍;而棉铃虫则更喜欢趋向于红花烟草，在涂有红花烟草叶片挥发物或叶片浸洗物纱布上的落卵量是黄花烟草上的2～6倍.Field inaestigation shows that the number of eggs of Helicoverpa assulta and H. armigera on rustic to bacco is significantly higher than and 6 ～ 20 times that on nicotiana tobacco for eaeny 100 plants. Indoor analysis cuas conducted to study the attraction effect of the leaf volatiles and leaf surface extnact to oriental tobacco budworm and cotton bollworm on oviposition. The results showed the leaf surface extractant of rustic tobacco had significant attraction effect to tobacco badworm on ovipositill and the number of eggs of oriental tobacco budworm on gauze treated with leaf and leaf surface extractant of rustic tobacco is 2 ～ 10 times that of nicotiana tobacco, while the cotton boolworms to be attracted to nicotiana tobacco and the number of egg of cotton bollworm on gauze treated with the leaf and leaf surface extractant of nicotiana tobacco is 2～6 times that of rustic tobacco.
