| 摘 要： | 利用Y形嗅觉仪观测了5种杀虫剂影响异色瓢虫和龟纹瓢虫对烟草叶片与烟粉虱复合体的选择行为。结果表明,在正常生长状况下,烟草叶片释放的挥发物对异色瓢虫和龟纹瓢虫无明显引诱作用,而烟草叶片受到烟粉虱危害后所释放的挥发性次生物质则对异色瓢虫和龟纹瓢虫有明显的招引作用;在杀虫剂处理后,30%毒死蜱和25 g/L溴氰菊酯几乎不会影响到瓢虫的搜索行为,30%啶虫脒则会显著降低瓢虫对猎物的选择率,20%吡虫啉和1.8%阿维菌素处理后,则会明显有利于瓢虫寻找猎物的行为。

| Abstract: | The orientation ofHarmonia axyridis （pallas） and Propylaeajaponica （Thunbery） to tobacco and prey whitefly combinations affected by insecticides was investigated with Y-tube olfactometer. The results showed that normal tobacco leaves did not produce plant vobtiles attractive to H. axyridis and P. japonica, while after being injured by whitefly, they produced herbivore-induced volatiles attractive to H. axyridis and P. japonica. Compared to the control, 30% chlorpyrifos EC, 25 g/L deltamethrin SC almost did not affect the ladybird＇s search behavior, 30% acetamiprid EC will significantly reduced the selectivity. While 20% imidacloprid WP and 1.8% avermectin EC obviously benefited the searching behavior ofH. axyridis and P. japonica. |
