摘要
长角广腹细蜂ＡｍｉｔｕｓｌｏｎｇｉｃｏｎｉｓＦｏｓｔｅｒ在湖南茶区是黑刺粉虱１～２龄幼虫的优势寄生蜂。其寄生的功能反应可用ＨｏｌｌｉｎｇⅡ型模型模拟，测定了不同温度条件对功能反应的影响，最适温度为３０℃，建立了α／Ｔｈ随温度而变化的回归模型，干扰反应可用Ｈａｓｓｅｌｌ和Ｖａｒｌｅｖ（１９６９）模型模拟，提出了寄生蜂自身密度干扰反应模型和寄生物一寄主相互干扰反应模型，采用回归旋转组合设计，建立了寄主密度（Ｎ）、寄生蜂密度（Ｐ）和温度（Ｔ）三因素五水平作用模型。
Amitus longiconis is a dominant parasite to the 1～2instar larvae of the spinywhite fly Aleurocanthus spiniferus in tea gardens of Hunan province。It was suggested thatthe functional response of Amitus longiconis to the spiny white fly be described by Holling’sⅡtype as the model given,the suitable temperature to parasitism be about 30℃ as the builtregressive model of a/Th with T,the interference parasitism among the parasites themself bedescribed by Hasseil& Varley’s model.The parasitism was built by means of rotation com-posite design of regression with 3 factors and 5 levels of each factor and has been discussed。
