摘　　要：以25%毒死蜱微囊悬浮剂为供试药剂,采用不同施药方法防治花生田中暗黑鳃金龟,从防治效果来看,喷穴处理(77.12%)>拌种处理(76.15%)>灌根处理(72.93%);从花生荚果产量来看,灌根处理>喷穴处理>拌种处理,灌根处理、喷穴处理、拌种处理分别比对照增产18.10%、15.74%、14.62%。上述3种方法防治蛴螬花生增产效果显著,可因地制宜采用。Different application methods of 25% chlorpyrifos micro -capsule SC were used to control the larvae of Holotrichia parallela in peanut fields. Their control efficacy from high to low was spot applying （77.12%）, seed dressing （76.15%） and root pouring （72.93%）. The peanut yield of different treatments showed root pouring 〉 spot applying 〉 seed dressing, and they increased by 18.10%, 15.74% and 14.62% respectively compared to the check.
