Determination of the responses of cotton bollworm helicoverpa armigera to plant volatiles by selective olfactometer 用选择性嗅觉仪测定棉铃虫对植物气味反应的研究

Provided with additional fresh hosts at emergence and the early stage of adult , the females showed no increased preference to volatiles in the y - tube olfactometer 羽化期和成虫初期是否投放新鲜寄主，对雌蜂的气味选择性没有明显的影响。

The learning behavior of scleroderma sichuanensis xiao fed on the fictitious hosts tenebrio molitor l . in the process of host foraging was studied using y - tube olfactometer 摘要采用y型嗅觉仪进行双向选择实验，研究了用替代寄主黄粉虫蛹繁殖的川硬皮肿腿蜂寄主搜索过程中的学习行为。

However , the number of hosts parasitized betwween chinese cabbage cultivars , or common cabbage cultivars was no difference . ( 4 ) the role of plant volatiles from the chinese cabbage and the common cabbage in host selection behaviour of d . semiclausum females was investigated by y - tube olfactometer 当白菜和甘蓝植株是完整的、或仅遭机械损伤时，两种蔬菜的挥发物对雌蜂的引诱力相似，而当植株遭受小菜蛾取食、或正在被小菜蛾取食时，白菜挥发物对雌蜂的引诱力较甘蓝的显著要强。

The results showed adult females preferred to lay more eggs on the chinese cabbage than on common cabbage . the amount eggs they laid on chinese cabbage cultivars or common cabbage cultivars were difference . ( 2 ) the role of plant volatiles from the chinese cabbage and common cabbage in host selection behaviour of p . xylostella adult was investigated by y - tube olfactometer 结果表明，无论是完整植株，还是机械损伤植株、虫损伤植株或虫-菜复合体植株，白菜挥发物对小菜蛾的引诱力都较甘蓝的大；而白菜或甘蓝各两个供试品种间的挥发物对小菜蛾的引诱力无显著差异。
