摘　　要：作者研究了叶色草蛉成虫捕食绣线菊蚜的功能反应和寻找效应,组建了其捕食功能模式:1/Na=0.0037+2.1137 1/N,处理时间(Th)为0.0037d,瞬时攻击率为0.4731,从中可看出叶色草蛉成虫的日最大理论捕食蚜量为270.3头(即N为无限大时),此模式表明这种天敌昆虫对绣线菊蚜有明显地控制作用,并有保护利用价值,其寻找效应随着蚜虫密度增加而降低。The writer had studied the functional reaction and catching effect that Chrysopa phyllochroma feeds on Aphis citricola.A mode of the functional reaction was founded.It is 1/Na=0.0037＋2.1137 1/N,handle time（Th） is 0.0037d.The rate of instantaneous attack is 0.4731.The most theoretical capacity for feed is 270.3 head.The model shows that Chrysopa phyllochroma powerfully controls Aphis citricola.It is the seek effect decreased with the aphid density increased.
