摘　　要：测定了35%辛硫磷微囊悬浮剂、25%毒死蜱微囊悬浮剂、10%二嗪磷颗粒剂、3%辛硫磷颗粒剂4种常用防治蛴螬杀虫剂在播种期和开花下针期使用对花生的保果效果和防虫效果。结果表明:25%毒死蜱微囊悬浮剂和35%辛硫磷微囊悬浮剂播种期使用的保果效果与防虫效果均优于开花下针期;而10%二嗪磷颗粒剂、3%辛硫磷颗粒剂开花下针期使用的保果效果和防虫效果均优于播种期。花生收获后对果仁的农药残留分析结果表明:在试验剂量下,各农药处理后花生仁中的农药残留水平均在0.01 mg/kg以下,符合日本肯定列表对各类农药残留限量的要求。A study was conducted to measure the control and residual effects of 4 organophosphorus pesticides that were widely used against peanut grubs （35% phoxim capsule suspensions, 25% chlorpyrifos capsule suspensions, 10% diazinon granules and 3% phoxim granules）. The results showed that 25% chlorpyrifos capsule suspensions and 35% phoxim capsule suspensions ought to be used at the sowing stage, but 10% diazinon granules and 3% phoxim granules ought to be used at flowering period in view of pod yield and pest control. A survey of pesticide residues in the fresh fruits was carried out. Pesticide residues in all of the samples were below the level of 0. 01 mg/kg, in line with the standards of various types of pesticide residue limits.
