烟盲蝽对斜纹夜蛾幼虫和烟蚜的捕食功能反应

The predacions capacity and functional response of Crytopeltis tenuisReuter to aphidus and larvae of Prodenia litura (Fabiricius)

在实验条件下，烟盲蝽对斜纹夜蛾１龄幼虫和低龄烟蚜的功能均属Ｈｏｌｌｉｎｇ－Ⅱ型（１９５９），其中，烟盲蝽成虫对斜纹夜蛾１龄幼虫的捕食功能反应参数为：ａ＝０．７３３１，Ｔｈ＝０．０２５９ｄ.烟盲蝽成虫对低龄烟蚜的功能反应参数为：ａ＝０．３１４３，Ｔｈ＝０００６３ｄ；烟盲蝽高龄若虫对低龄烟蚜的功能反应参数为：ａ＝０．３０１２，Ｔｈ＝０．０２２２ｄｏ烟盲蝽成虫自身密度的干扰反应均符合Ｈａｓｓｅｌｌ－Ｖａｒｌｅｙ（１９６９）模型，它对斜纹夜蛾１龄幼虫的干扰反应满足Ｅ＝０．４０４１Ｐ(-５９６８)，对低龄烟蚜的干扰反应可用Ｅ＝０．２４６９Ｐ(－０６０７９)

The predacious capacities and functions of Crytopeltis tennis Reuter to Prodenia litura (Fabricius) and Aphidusgifuensis Ashmead were studied in this paper. Equations belong to the functional response of Holling-Ⅱ phase. Interfering response of equations belong to Hassell-Varley phase. All researches were studied in the laboratory.
