摘　　要：在不同温度下，分别用Holling-Ⅱ型方程和Holling-Ⅲ型方程拟合日本方头甲对矢尖蚧一龄雄若虫的捕食作用。结果显示瞬间攻击率在20-25℃范围内随温度的升高而增大，30℃以后缓慢下降；最大捕食量随温度的升高而增大；平均处理时间随温度的升高而减少。说明25℃以上的高温有利于日本方头甲对矢尖蚧的捕食。The functional response of Cybocephalus nipponicus Endrfidy-Younga to yanon scale 1^th instar of male, were simulated by Holling- Ⅱ model and Holling-Ⅲ model under different temperature.The results indicated that there were significant differences among predacious number at various temperature. Maximal predacious number increased and the average handling time were decreased with increase temperature, while rate of successful attack ascending under 20-25 ℃, then began to drop slowly. Thus the predation of C. nipponicus was benefit to the higher temperature above 25℃.
