摘　　要：对临夏地区辽梨喀木虱的生物学特性进行了定点调查和室内饲养观察,结果表明,辽梨喀木虱在临夏1 a发生2代,若虫共5龄,10月下旬至11月下旬以2龄若虫在芽腋、枝杈处固着越冬。应采用重点防治初出蛰的越冬若虫、保护和利用天敌昆虫多样性等措施加以控制。The biological characteristics of Psylla liaoli were investigated under laboratory condition in Linxia region. The results showed that it has two generations annually in Linxia region, the nymph has five instars, the II instar nymph on axiUary bud and the branch axils be used overwintering in late October to late November.
