用触角电位法研究了大豆蚜、棉蚜和桃蚜对39种挥发性次生化合物的反应,结果如下:1)绿叶气味化合物及其异构体的去极化电压远强于萜烯类;具有6个碳原子的醇类和醛类是最有活性的化合物.2)大豆蚜和棉蚜对醛类和脂类的反应要比对相应的醇类强,这与桃蚜的实验结果刚好相反.3)蚜虫嗅觉系统所显示的活性与刺激化合物的结构有关,醇类和醛类刺激所引起的EAG饱和的要比不饱和的强.4)大豆春迁蚜对萜烯衍生物(醇、醛、脂)的触角电位反应高于棉蚜,而对萜烃化合物的反应刚好相反.5)各种化合物引起的EAG峰形不同;牛儿醇、癸醇和香茅醇刺激所引起的波形回复最慢,而在直链饱和醇中随着碳原子数的增加而回复速度减慢.
The responses of soybean aphid, cotton aphid and Myzus persicae to 39 kinds of volatile secondary compounds were studied by the antenna potential method. The results are as follows: 1) The depolarization voltage of green leaf odor compounds and their isomers is much stronger than that of terpenes; Alcohols and aldehydes with 6 carbon atoms are the most active compounds.2) The response of soybean aphid and cotton aphid to aldehydes and lipids is stronger than that of the corresponding alcohols, which is just as good as that of peach aphid Conversely, 3) the activity exhibited by the aphid olfactive system is related to the structure of the stimulating compound, and the saturation of EAG induced by alcohols and aldehydes is stronger than that of unsaturation.4) , Aldehydes, and lipids) were higher than those of cotton aphids, while the responses to terpenoid compounds were just the opposite.5) The peak shapes of EAG caused by various compounds were different. The waveforms induced by bortezomidine, decyl alcohol and citronellol The slowest response, while in straight-chain saturated alcohol as the carbon number increases and slow down the recovery rate.
