中文摘要: |
日光温室条件下,分别以温室粉虱和烟粉虱作为扩繁寄主,建立起稳定的2种丽蚜小蜂种群(分别以E1和E2表示)。对这2种不同寄主来源的丽蚜小蜂在番茄、黄瓜、菜豆、茄子上烟粉虱和温室粉虱的寄生率进行了研究与比较。结果表明,E1和E2对4种寄主植物上温室粉虱的控制作用均显著大于对烟粉虱的控制作用;E1对茄子和黄瓜上的粉虱类害虫的控制作用较好,E2对4种植物间粉虱类害虫的控制作用无显著差异。2种小蜂在4种植物上烟粉虱的寄生率,除番茄上E1(27.84%)低于E2(42.22%),差异显著,其余3种植物上,均是E1高于E2,差异显著;2种小蜂在4种植物上对温室粉虱的寄生率,均是E1高于E2,差异显著,即对于4种植物上的粉虱类害虫的控害效果E1要相对优于E2。 |
英文摘要: |
Parasitism of two Encarsia formosa Gahan populations reared on Trialeurodes vaporariorum (Westwood) and Bemisia tabaci (Gennadius) separately for several generations (represented as population E1 and E2, respectively) to B.tabaci and T.vaporariorum on tomato, cucumber, kidney bean and eggplant, was investigated in the greenhouse. The parasitism rates of E1 and E2 on T.vaporariorum were significantly higher than those on B.tabaci from all of the four plants. The parasitism rates of E1 to whiteflies on cucumber and eggplant were much higher than those on the other two plants. However, there was no obvious difference in the parasitism rates of E2 to whiteflies among four plants. The parasitism rates of E1 to B.tabaci on all of the plants were significantly higher than those of E2 except for tomato. Similarly, the parasitism rates of E1 to T.vaporariorum were significantly higher from the four plants than those of E2. |
