摘　　要：在14、18、22、26、30℃5个温度下,测定了榆紫叶甲赤眼蜂(Asynacta ambrostomae)对榆紫叶甲(Ambrostoma quadriimopressum)卵的寄生功能反应。结果表明:试验温度条件下,榆紫叶甲赤眼蜂的寄生能力随着温度的升高而增加;各温度的功能反应数据均能用Holling-Ⅱ圆盘方程很好地拟合;瞬时攻击率及理论最大寄生率均随温度的升高而增大,理论最大寄生量14℃为55.88粒,30℃时达到117.48粒。We studied the functional response of Asynacta ambrostomae to the eggs of Ambrostoma quadriimopressum at 14 ℃,18 ℃,22 ℃,26 ℃ and 30 ℃,respectively. The parasitic ability of Asynacta ambrostomae enhanced with the increasing of temperature,and the functional response fitted well by Holling-II equation at 14 ℃-30 ℃. The rates of the successful attack and the maximum parasitic rose with the increase of temperature,and the maximum parasitic number were 55.88 and117.48 at 14 ℃ and 30 ℃,respectively.
