| 摘 要： | 采用药膜法测定了溴氰菊醋、甲氰菊酯、氰戊菊酯和三氟氯氰菊酯对广赤眼峰（ＴｒｉｃｈｏｇｒａｍｍａｅｖａｎｅｓｃｅｎｓＷｅｓｔｗｏｏｄ）、螟黄赤眼峰（Ｔ．ｃｏｎｆｕｓｕｍＷｉｇｇｉａｎｉ）、松毛虫赤眼峰（Ｔ．ｄｅｎｄｒｏｌｉｍｉＭａｓｔｓ．）成蜂的毒力。结果表明，不同药剂对同一种赤眼峰成蜂的毒力不同；不同赤眼蜂种群的成峰对同一药剂的反应差异也较大，其中溴氰菊酯的毒力最大（ＬＣ＿（５０）＜２．３０μｇ·ｍＬ￣（－１）），甲氰菊酯相对较小（ＬＣ＞１２．５０μｇ·ｍＬ￣（－１））；３种赤眼峰中，以广赤眼蜂对药剂反应较迟钝，忍受能力较强。

| Abstract: | The toxicity of several pyrethroids(decamenthrin , fenpropathrin,fen-valerate and cyhalathrin ) to Trichograma evanescens Westwood,T.confusum Wiggianiand T. dendrolini Masts. was determined by means of toxicfilm. The results indicatedthat different pesticides showed different activities to the same adult trichogrammatidsand different species of adult trichogrammatids vary in their reactions to the same pesti-cide. Decamethrinwas the most powerful one among all these pesticides and T.e-vanescens was more tolerable than the other two. |
