摘要
采用浸叶法测定了杀虫单分别与几种有机磷杀虫剂混配对粘虫3龄幼虫的联合毒力。结果表明杀虫单与敌百虫以1∶3比例混配对粘虫表现为显著增效,共毒系数(CTC)为268.11;杀虫单与三唑磷以1∶1、4∶3和1∶2的比例混配对粘虫表现为增效作用,共毒系数(CTC)分别为132.98、140.21和132.74;杀虫单与毒死蜱以4∶1的比例混配表现为增效作用,共毒系数(CTC)为192.91。
Synergism of organophosphate insecticides by monosuhap against the third instar larvae of oriental armyworm Mythimna separata were studied in the laboratory using leaf dipping method. The results showed that the significant synergistic action were observed in combination of monosultap plus trichlorphon（1：3）, monosultap plus triazophos （1：1,4：3 and 1：2）, monosuhap plus chlorprifos （4：1） against the oriental armyworms, and their co-toxicity coefficient （CTC） was 268.11,132.98,140.2,132.74 and 192.91, respectively.
