黑龙江省帽儿山地区水曲柳花小蠹生物学特性及防治对策

目的]研究黑龙江省帽儿山地区水曲柳花小蠹（Hylesinus fraxiniPanzer）的生物学特性及防治对策。方法]采用野外调查与室内试验结合的方法。结果]水曲柳花小蠹在黑龙江省帽儿山地区1年发生1代,以成虫在树干树皮下越冬。成虫5月中旬出现,侵入衰弱木或新伐倒原木交配产卵,5月下旬孵化出幼虫,7月上旬开始化蛹,下旬开始羽化出成虫。目前应以检疫措施为主要防治手段,提防或严禁调入,防止苗木、木材及其制品带虫传播。结论]该研究可为水曲柳花小蠹的综合治理提供参考。

Biological Characteristics of H.fraxini Panzer and Its Control Countermeasures

Objective] The research aimed to study the biological characteristics of H.fraxini Panzer and its control countermeasures in Maoershan,Heilongjiang Province.Method] The investigation in field and observation in lab were used.Result] H.fraxini Panzer has one generation a year in Maoershan,Heilongjiang Province and overwinters as adults in host barks.In the middle of May,adults appeared and invaded debilitating wood or new fallen log mating spawning.In late May larvae hatched.In early July,larvae pupate and pupa started eclosion in late July.We should strengthen quarantine to quarantine measures for the main prevention and treatment,and be ware of seedlings,wood and its products with worms spread.Conclusion] The study can provide references for integrated management of H.fraxini Panzer.
