摘　　要：本文对黄足肥螋Euborellia pallipes(Shiraki)的发生及其对苹果绵蚜Eriosoma lanigerum(Hausmann)的捕食作用开展了研究。结果表明:7～9月份是黄足肥螋田间发生高峰期,它对苹果绵蚜E.lanigerum(Hausmann)的功能反应符合HollingⅡ,Na=0.9804N/(1+0.0108N),其捕食量随苹果绵蚜密度的增加而增加,日最大捕食量和最佳寻找密度可达46.3头和19.9头。在15～30℃下,黄足肥螋的捕食量随温度的升高而增加,每头成虫在10、15℃、18℃、20℃、25℃和30℃下的取食量分别为3.3头、20.3头、23.8头、25.8头和27.0头。研究表明了黄足肥螋是苹果绵蚜的主要捕食性天敌昆虫之一,应加强保护与利用。The paper reported an earwig Euborellia pallipes （ Shiraki ）, preyed apple orchards. We investigated the occurrence of E. pallipes in fields and studied boratory. The results showed that the population peak period of the predatory was on Eriosoma lanigerum in its predatory control in lafrom July to September in apple orchard. The functional response model of the earwig adult preyed on E. lanigerum was Na = 0. 9804N/ （ 1 ＋ 0. 0108N） . The daily uptake of the earwig was increased with the aphid density and temperature. The daily maximum uptake of prey and the optimal searching efficiency were 46. 3 and 19.9 aphids, respectively. Under 10℃, 15℃, 18℃, 20℃, 25℃ and 30℃, the daily uptake of an earwig was 3.3, 20. 3, 23.8, 25.8 and 27.0 aphids, respectively. The results showed that E. pallipes is an important predatory of E. lanigerum and should be protected and utilized in the apple orchard.
