摘要
在实验室条件下研究了红基盘瓢虫对橄榄星室木虱的捕食作用。红基盘瓢虫对橄榄星室木虱的功能反应符合ＨｏｌｌｉｎｇⅡ型，而两种瓢虫（红基盘瓢虫和红星盘瓢虫）共同作用于橄榄星室木虱的功能反应符合ＨｏｌｌｉｎｇⅢ型（Ｓ型）。红基盘瓢虫对自身密度的功能反应可用Ｂｅｄｄｉｎｇｔｏｎ模型拟合；其搜索效率与个体间相互干扰的关系呈幂函数下降，可用Ｈａｓｓｅｌｌ＆Ｖａｒｌｅｙ模型模拟；搜索效率与猎物密度。
Researches were carried out on the predation of Lemnia circumusta toPseudophacopteron canarium in labortory conditions. At 30.1±0.8℃,the functionalresponse of Lemnia circumusta to Pseud ophacophacopteron canarium was suited to Holling's typeⅡ,which was described by Holling disc equation,Na=0.95112Nt/(1+0.00077Nt);whilethat of two ladybirds,Lemnia circumusta and Phrynocaria congener to Pseud ophacopteroncanarium was suited to Holling's type Ⅲ,which could be simulated as S-shape curve, N_a=.The functional response to the density of Lemnia circumustaitself fitted Beddington's equation,N_a=;the mutual interferenceamong predator individuals could be simulated by Hassell &.Varley’s equation,E=0.84645P;the searching efficiency to prey and predator density was E=
