摘要：笋用林是杭州市富阳区重要的经济林资源,但近年来受到竹林地下害虫的严重威胁。本研究调查了杭州市富阳区毛竹Phyllostachys edulis林、早竹P.praecox林及高节竹P.prominens林笋期地下害虫的种类及危害情况,并开展了平沙绿僵菌Metarhizium pingshaense对竹林金针虫Melanotus cribricollis的生物防治试验。结果表明,富阳区笋期主要地下害虫有竹林金针虫、浙江栉蝠蛾Bipectilus zhejiangensi、白蚁Odontotermes formosanus和露尾甲Haptonchus sp.4种,其中,以竹林金针虫危害最严重,造成种笋退笋率高达37.78%~62.93%。林间利用平沙绿僵菌颗粒剂防治竹林金针虫效果显著,施放2年后的防治效果达80.00%,可应用于生产。
In March and April 2017,investigations were carried out every 7 days on damaged shoots and degraded shoot at Phyllostachys edulis,P.praecox and P.prominens stands in Fuyang,Zhejiang province.Insects found were fed in lab.In 2017 and 2018,experiment was made on control of Melanotus cribricollis by Metarhizium pingshaensis.The results showed that there were four main soil insects,namely M.cribricollis,Bipectilus zhejiangensis,Odontotermes formosanus and Haptonchus sp.,especially M.cribricollis,causing 37.78%-62.93%death of shoot.The experiment demonstrated that M.pingshaensis had significant control efficiency against M.cribricollis,the control effect was 80%after 2 years consecutive application.
