【摘要】：为了解棉平突蚜茧蜂Lysiphlebia japonica(Ashmead)对取食不同寄主植物棉蚜Aphis gossypii Glover的偏好性,进行了相关的虫口动态、寄生率和体重等参数的调查。虫口动态结果表明,棉田和罩笼中西葫芦上棉蚜、棉平突蚜茧蜂和僵蚜数量均最多,与棉花和黄瓜上的相比有显著差异。室内和罩笼中西葫芦上棉蚜的体重较大,约0.36 mg,显著高于棉花和黄瓜上的棉蚜体重。室内寄生试验结果表明,棉平突蚜茧蜂在西葫芦上对棉蚜的寄生率较高,其中来源于西葫芦上的棉平突蚜茧蜂对西葫芦、棉花和黄瓜上蚜虫的寄生率分别为81.3%、58.3%和44.0%。本文初步明确了棉平突蚜茧蜂对西葫芦具有偏好性,为棉平突蚜茧蜂在生物防治上的应用提供一定的理论指导和实践依据。
[Abstract]:In order to understand the process of Lysiphlebia japonica cotton flat Aphidiidae (Ashmead) preference for feeding on different host plants of cotton aphid Aphis gossypii Glover survey, were related to the insect population dynamics, parasitism rate and weight parameters. The results showed that the insect population dynamics, cotton and cage pumpkin are most cotton aphid, cotton flat and stiff Aphidiidae aphid number suddenly, there was a significant difference compared with cotton and cucumber. Indoor and cage pumpkin on cotton aphid weight is larger, about 0.36 mg, significantly higher than that of cotton and cucumber aphid weight. Parasitic indoor test results show that the process of Aphidiidae in cotton flat zucchini parasitic on Aphis gossypii was higher, which comes from the process of cotton flat Aphidiidae zucchini on zucchini, cotton and cucumber aphid parasitism rate were 81.3%, 58.3% and 44%. This paper initially identified cotton flat Aphidiidae process has a preference for zucchini, to provide some theoretical guidance and practical basis for the application of cotton flat Aphidiidae in biological control of the process.
