摘要
中华通草蛉幼虫1-3龄对绣线菊蚜的功能反应和2龄幼虫的种内干扰效应研究表明：功能反应均属HolingⅡ型，功能反应的参数说明中华通草蛉对控制绣线菊蚜具有保护利用价值；2龄幼虫的干扰效应用Hassell ＆ Varley的模式（E=QP^m）进行模拟，模拟模型为E=0.2651p^-0.2106，结果说明，随着2龄幼虫密度的增大，其捕食作用率随之减小。
Laboratory tests were conducted to evaluate the functional responses of the larvae of Chrysoperla sinica to Aphis citricola and the mutual interference among the 2nd instar larvae. The results indicated that all the larva stages of Ch. Sinica showed the Holling Ⅱ functional response. The mutual interference among the 2nd instar larvae could be simulated by the model of E=QP^-m which was put forward by Hassell ＆ Varley, and the model was E = 0.2651P^-0.2106 which indicated that the rate of predatory function of Ch. Sinica decreased with the increase of the 2nd larvae density.
