摘　　要：从保护天敌的角度出发,以敌敌畏、印楝素乳油和清水作对照,测定了胜红蓟提取物对拟澳洲赤眼蜂的成蜂和蛹毒性以及对赤眼蜂的寄生抑制作用的影响。结果表明,胜红蓟提取物对拟澳洲赤眼蜂的寄生作用以及对其蛹的羽化没有影响,但对成蜂存活具有一定的影响,但其影响明显低于印楝素及敌敌畏。In this paper, effect of secondary chemicals of two plants, Ageratum Conyzoides L., neem and one insecticide, DDVP, on the adult wasp and pupae of Ageratum Conyzoides was conducted in the laboratory.
