摘要：

本文研究了广腹螳螂对龙眼长跗萤叶甲的功能反应。结果表明，室内自然条件下，广腹螳螂对龙眼长跗萤叶甲的功能反应符合 Holling圆盘方程Ⅱ型，其模型为 Na=0.448Nt/(1+0.01238Nt) , 瞬时攻击率(寻找效率) a′=0.448，广腹螳螂捕食1头长跗萤叶甲的时间Th=0.02759h, 最大捕食量1/Th=36.24头。广腹螳螂寻找效应随其自身密度的增加而降低， 其数学模型为：E=0.328P-0.355。以上模型为评价广腹螳螂控制龙眼长跗萤叶甲的作用提供了科学依据。

Abstract:

The predation of Hierodula patellifera serville on the Monolepta occifuvis Gressitt et Kimoto was studied in the laboratory. The results showed under the natural condition that functional response of H. patellifera serville to adults of M. occifuvis was determined as Holling’s type Ⅱ, the model was Na=0.448Nt/(1+0.01238Nt), a′=0.448, Th=0.02759h, the maximum predation was 36.24. The searching efficiency was de-creased with the increase of the density of themselves, and the mathematic model was E=0.328P-0.355. The model concerned provides scientific support for evaluation of the control effect of H. patellifera serville to adults of M. occifuvis.
