作者测定了保幼激素类似物ETP即4—[2—(特丁基甲酰氧基)丙氧基]苯甲酸乙酯对苹果小卷叶蛾(Adoxophyes orana)的毒理效应,其作用主要表现在以下两方面:①ETP处理幼虫,使变态异常产生了幼虫一蛹中间体,以不正常蛹等级率为指标的半有效剂量分别为:点滴ED_(50)=29.80μg/头、幼虫饲喂EC_(50)=161.57mg/L、田间喷洒EC_(50)=1075mg/L;②ETP处理幼虫,使雌蛾产卵力明显下降,其半有效剂量分别为:点滴ED_(50)=9.58μg/头、幼虫饲喂EC_(50)=206.7mg/L、田间喷洒EC_(50)=914mg/L。
The authors determined the toxicological effects of the juvenile hormone analogue ETP, ethyl 4- [2- (t-butyl formateoxy) propoxy] benzoate, on Adoxophyes orana and its effects are mainly shown in the following two In terms of: ①ETP treatment of larvae, so abnormal metamorphosis produced larvae pupae intermediates, abnormal pupal grade rate as an index of the semi-effective doses were: drip ED_ (50) = 29.80μg / head, larvae fed EC_ (50) = 161.57mg / L, spraying EC50 (50) = 1075mg / L in the field; ②ETP larvae significantly decreased the oviposition ability of female moths. The effective dose of ED50 was 9.58μg / Feeding EC_ (50) = 206.7mg / L, field spraying EC_ (50) = 914mg / L.
