摘　　要：经室内测定和田间试验表明 ,体积分数 40 %水胺硫磷乳油、体积分数 2 8%棉虫净乳油等对棉铃虫卵具有较强的杀伤力 ,可作为卵期防治用主选药剂。体积分数 30 %甲久乳油混剂对抗性棉铃虫毒力达显著增效作用 ,大田药效试验 10 0 0～ 15 0 0倍防效达 90 % ,达到或超过常用混剂体积分数 30 %灭铃灵乳油 15 0 0倍及体积分数 5 %来福灵乳油 2 0 0 0倍 ,且具有成本低 。The result of indoor and field tests showed that iscocarbophos 40% EC and mianchongjing 28% EC could kill the eggs of bollworms effectively,and it could be used as the main control pestcides during the period of egg laying.30% Jiaju EC had better effect on killing resistant bollworms,the pestcide control effect on the field bollworm was 90%,and was higher than that of 1 500× 30% Mielingling EC and the 2 000× 5% Sumi alphe EC,the pesticide had low cost and long pest killing effect.
