摘　　要：在17℃、20℃、25℃、30℃和34℃5个温度条件下,就布氏潜蝇茧蜂Fopius vandenboschi(Fullaway)对橘小实蝇Bactrocera dorsalis(Hendel)幼虫的寄生作用进行了研究.结果表明,在17-34℃范围内,其功能反应数据均能用Holling圆盘方程拟合,其瞬时攻击率随温度的升高而增大,34℃时瞬时攻击率达到最大值且显著高于其他温度的瞬时攻击率,其处理时间最短.各处理温度下,布氏潜蝇茧蜂的自身密度干扰作用均符合Hassell-Varley模型(a=QP-m),干扰系数随温度的升高而增大.The functional response of Fopius vandenboschi （Fullaway） to the larvae of Bactrocera dorsalis （Hendel） at temperatures 17 ℃ ,20 ℃ ,25 ℃ ,30 ℃ and 34 ℃ was examined. The results showed that the functional response could be described by the disc equation of Holling at all test temperatures. The rates of successful attack rose with the increase of temperature, reaching the highest at 34 ℃, which was significantly higher than those at 17 -30 ℃, but the handling time was the shortest. The interference response of F. vandenbosch to itself density was fitted to the Hassell-Varley＇ s model a = QP^m at all tested temperatures, the influence coefficient increased with the increase of temperatures.
