摘  要：
筛胸梳爪叩甲是目前笋用竹林主要的地下害虫。采用室内饲养与室外调查相结合的办法对该虫的形态特征、生活史及各虫态的生活习性进行研究。该虫4~5 a发生1代,以成虫及各龄幼虫越冬;4月下旬至6月底为成虫羽化期,5月中旬为羽化盛期;2-3月越冬幼虫开始活动,4月中下旬为幼虫活动盛期,6-8月幼虫进入越夏期,活动量减少,9月气温下降,幼虫又开始活动,11月进入越冬期;7月底至8月上旬,4年生幼虫老熟结土茧化蛹,蛹约经25 d羽化成虫越冬。防治建议幼虫期活动盛期(4月)用BT可湿性粉剂800~1 000倍泼浇林地,或在垦复时用750 kg/hm2茶籽饼拌土施入。成虫期可用黑光灯诱杀,均有一定防治效果。

摘  要：
Melanotus cribricollis is a major underground pest of shoot-use bamboo stand in Zhejiang province.Study on morphological properties,life history and behavior of different development stages of M.cribricollis by indoor feed and field investigation.The insect had one generation each 4-5 years,overwintered by adult and larva.Adult emergence occurred from the end of April to the end of June,peaked in the middle ten-day of May.Overwintered larva had activities in February or March,peaked in the middle ten-day of April.Larva activities decreased from June to August,but increased again in September along with the decline of temperature till it started to overwinter from November.4-instars larva entered pupating from the end of July to early August,and in about 25 days the adults emerged to overwinter.Suggestions were made to control the pest such as splashing 800-1000-fold of wetting powder of BT in bamboo stand,and fertilizing with rape cake of 750kg/hectare during reclamation in April.Black-lighted lamp can be used to trap the insect during adult period.
