摘要
采用点滴法测定了“双扑”及其组成单剂对棉铃虫的毒力和增效作用。结果表明：药后２４ｈ，双扑对棉铃虫的ＬＣ５０值为７．２８ｐｐｍ，其共毒系数为２８３．２１，说明双朴对棉铃虫具有显著的增效作用。
The toxicity and synergistic effects of a insecticide mixture Shuangpu were investegat-ed.The LC50 of Shuangpu to Heliothis armigera was 7.28ppm,the co-toxicity coefficiencyof Shuangup was 283.21.It was clear that the mixture Shuangup had very strong synergis-tic effects to Heliothis armigera.
