Abstract: To ascertain the control potential of Propylaea japonica on Coccus hesperidum,the functional response and searching efficiency of P.japonica(4th instar larvae and adults) on C.hesperidum(1st instar nymph) were studied at different temperatures and spatial scales in a manual climatic box. The results showed that the predation efficacies of P. japonica (4th instar larvae and adults) on C. hesperidum (1st instar nymph) affected by temperature and spatial scale all confirmed to the HollingⅡdisc equation,but had different functional response parameters.The predation efficacy (a′/Th) and searching efficiency of P.japonica (4th instar larvae and adults) on C.hesperidum(1st instar nymph) had a quadratic function relationship with temperature,with the maximum at 25℃ and a suitable temperature of 21—29℃ .The predation efficacy and searching efficiency of P.japonica (4th instar larvae and adults) on C.hesperidum(1st instar nymph) decreased with the increase of test space.

Key words: Propylaea japonica, Coccus hesperidum, Functional response, Searching efficiency, Temperature;Spatial scale

摘要: 为探明龟纹瓢虫对褐软蚧的控制潜能,在人工气候箱中研究了不同温度和空间下龟纹瓢虫(4龄幼虫、成虫)捕食褐软蚧1龄若虫的功能反应及寻找效应。结果表明,在不同试验温度和空间下,龟纹瓢虫(4龄幼虫、成虫)对褐软蚧1龄若虫的捕食功能反应均符合HollingⅡ型圆盘方程,但其功能反应参数存在差异。龟纹瓢虫(4龄幼虫、成虫)对褐软蚧1龄若虫的控制效能(a′/Th)和寻找效应均与温度呈二次函数关系,最高峰出现在25 ℃,21~29 ℃是龟纹瓢虫(4龄幼虫、成虫)捕食褐软蚧1龄若虫较为适宜的温度范围。龟纹瓢虫(4龄幼虫、成虫)对褐软蚧1龄若虫的控制效能和寻找效应随试验空间的增大而降低。
