| 摘 要： | 通过对黑带食蚜蝇对烟蚜的捕食作用研究，得到1，2，3龄幼虫对烟蚜的捕食功能反应模型为Na=0.249 7 N/(1+0.249 7×0.148 6 N），Na=1.175 6 N/(1+1.175 6×0.029 8 N)，Na=0.989 9 N/(1+0.989 9×0.005 0 N)，日最大捕食量依次为6.73头，33.56头，202.1头。结果表明，利用黑带食蚜蝇防治烟蚜是有一定潜力的。

| Abstract: | Epistrophe balteata De Geer is one of the dominant species in the tabacco field in Yunnan. The functional response analysis shows that it predation efficiency to Myzus persicae is a negative acceleration curve. Holling's (1959) disc equation has been used to describe syrphid predation to the aphid. Its functional model is as follows:1st instar larva: Na=0.249 7 N/(1+0.249 7×0.148 6 N) 2nd instar larva: Na=1.175 6 N/(1+1.175 6×0.029 8 N)3rd instar larva: Na=0.989 9 N/(1+0.989 9×0.005 0 N)The most consuming rate by Epistrophe balteata to Myzus persicae per day is 6.73，33.56，202.1, respectively. |
