释放胡瓜钝绥螨控制毛竹害螨的研究

Release of Amblyseius cucumeris(Acari: Phytoseiidae)to control pest mites of moso bamboo

摘要: 1999~2002年在福建省南平、永安2个受螨害严重的毛竹产区,通过释放胡瓜钝绥螨(Amblyseiuscu cumeris Oudemans),调节毛竹林益、害螨比例,显著地控制了南京裂爪螨(Schizotetranychus nanjingensis Ma Yuan)、竹裂爪螨(S. bambusae Reck)、竹缺爪螨(Aponychus corpuzae Rimando)、竹刺瘿螨(Aculus bambusae Kuang)等毛竹害螨的种群增长,控制效果分别达84.00%、99.37%、100.00%、100.00%;与对照区比较.以螨治螨生防区的捕食螨总量增加了73.45%(释放后1个月)和12.18%(释放后2个月);毛竹长势明显优于对照区。

Abstract: The studies on releasing of Ambiyseius cucumeris Oudeman to control pest mites in moso bamboo forests of Nanping and Yongan cities where seriously damaged by mites during 1999-2002 were conducted. The result showed that the densities of Schizotetranychus nanjingensis Ma Yuan, S. bambusae Reck, Aponychus corpuzae Rimando, Aculus bambusae Kuang reduced significantly to 84.00% , 99.37% , 100.00% and 100.00% respectively. The number of predatory mites at bio-control area increased by 73.45%(1 month after releasing)and 12.18%(2 monthes after releasing)compared with those of CK. The moso bamboo grew best compared with CK.
