摘　　要：为掌握李小食心虫的发生规律,筛选防治李小食心虫的有效药剂,开展了李小食心虫性诱剂监测及防治试验。结果表明:李小食心虫在河南省林州市1a发生2代,越冬代成虫高峰期出现在4月上旬,1代成虫高峰期出现在6月上旬,越冬代成虫发生量大,占诱虫总量的68.4%,1代成虫发生量少,占诱虫总量的31.6%;采用10%的阿维除虫脲乳油500倍液、1 000倍液、1 500倍液,20%的毒死蜱微囊悬浮剂500倍液、1 000倍液,20%的氰戊马拉松乳油500倍液,树冠喷雾防治李小食心虫,越冬代成虫高峰期出现后连续喷药2次,间隔期15d,1代成虫高峰期出现后喷药1次,防效在83%以上,但从经济方面考虑,以20%的毒死蜱微囊悬浮剂500倍液及10%的阿维除虫脲乳油1 000倍液最为经济有效。In order to master the occurrence rules of plum fruit moth（Grapholitha funebrana Treitscheke）and screen for efficient chemicals pesticides in fields, sex attractant monitoring and control experiment was carried out. The results showed that G. funebrana had two generations per year in Linzhou city of Henan province. The maximum occurrence of the overwintering adult of G. funebrana was in the early April and the first generation of adult peak in early June. Overwintering adults generates was large and the first generation less accounting for 68.4 % and 31.6 % respectively. The field efficacies of 3% avermectin-diflubenzuron EC diluted 500,1 000 and 1 500 times, 20 % chlorpyrifos SC diluted 500,1 000 times and 20 % fenvalerate-malathion were very good and the preventing effect all reached above 83 %. But from the economic considerations, the most effective and the most economic was 20% chlorpyrifos SC diluted 500 times and avermectin-diflubenzuron EC diluted 1 000 times.
