新型杀虫混剂MA-95的室内研究

Study on a New Insecticide Mixture MA 95 in Laboratory

以棉蚜为测试对象，采用共毒系数法对杀虫混剂ＭＡ－９５进行了测试，其共毒系数最高达２７２．６。对棉蚜、柑桔全爪螨、菜青虫的比较毒力测定结果表明：ＭＡ－９５的毒力为标准药剂２．４６～９．９３倍，对棉铃虫的ＬＤ５０与拟除虫酯类的复配剂铃螨净近似，但最大致死剂量较后者小１．３４倍。

According to co toxcity coeffcient mothod the MA 95 insecticide mixture was selected with the highest co-toxcity coefficient 272 6 using cotton aphid as testing target. Comparing poison testing to cotton aphid, citrus red mife and cabbge caterpillar, the poison of MA 95 was 2.46￣9.93 times of the standard medicine, and its LD 50 to cotton bollmorm was approxinated to that of Lingmanjing,the pyrethrin mixture, but the hightest lethal poison was less 1 34 times than that of the standard medcine.
