为了对蔬菜地蚜虫的生物防治提供参考，研究了烟蚜茧蜂对烟蚜和萝卜蚜的寄生功能反应。结果表明：烟蚜茧蜂的寄生作用受蚜虫密度影响，寄生数量随蚜虫密度的增加而增加；烟蚜茧蜂对烟蚜和萝卜蚜的寄生功能反应均符合 HollingⅡ型曲线，寄生功能反应模型分别为 Na＝0．5153 N／（1＋0．0168 N ）和 Na＝0．1906 N／（1＋0．0204 N）；烟蚜茧蜂对蚜虫的寄生数量与蚜虫密度呈正相关，寻找效应与蚜虫密度呈负相关，烟蚜茧蜂对烟蚜的寄生作用强于萝卜蚜。

To provide references for biological control of aphids in vegetable fields,the parasitic functional response of A.gifuensis on M.persicae and L.erysimi was studied.Results:A.gifuensis’s parasitic action was affected by aphid density,the parasitic amount of A.gifuensis to aphid increased with the increase of aphid density.The functional response of A.gifuensis to M.persicae and L.erysimi were fitted to Holling Ⅱ type equation.Na=0.515 3 N/(1+0.016 8 N)on M.persicae,Na=0.190 6 N/(1+0.020 4 N )on L.erysimi.The parasitic function of A.gifuensis was positively related with aphid densities,as its searching efficiency was negatively associated with aphid densities.And A.gifuensis ’s parasitic effects and searching efficiency to M.persica were all stronger than that to L.erysimi.
