| 摘 要： | 通过饲喂含有Ｌ—刀豆氨酸的中国白菜叶片，Ｌ—刀豆氨酸对菜蛾幼虫的生长发育影响表现为：直接杀死幼虫，幼虫体重减轻，幼虫生长发育延缓，蛹及成虫畸形。２龄幼虫对Ｌ—刀豆氨酸的反应程度取决于刀豆氨酸的浓度，至少在０．０１２—０．０４８ｍｇ／ｃｍ２范围Ｌ—刀豆氨酸与幼虫的反应呈正相关。Ｌ—刀豆氨酸对菜蛾幼虫有一定的拒食作用。本研究为探索防治害虫的新路奠定了理论基础。

| Abstract: | Effect of L-canvanine on the development of larvae of P.xylostella by feeding Chinses cabbage leaf squares freated with L-canavanine included larval mortality, decreased gained body weight , metamorphic disorder and morphological abbezations.2 nd instar larvae of P.xylostella response to L-cavaanine was concertration-dependent at least over a range of 0^012_0^048 mg/cm 2.L-canavanine also exhibited antifeeding activity on larvae of P. xylostella by a leaf aera consumed test. |
