摘要
南京裂爪螨在福建主要危害毛竹，７～８月高温干燥季节危害最重，造成毛竹大量落叶，直到枯死。该螨于１１月上旬进入休眠，翌年２月下旬出蛰，３月上旬开始产卵，世代重叠，雌雄比为１３．１１。应用５０％甲胺磷、４０％氧乐果、２０％杀灭菊酯、２０％灭扫利、２０％快灵、５％抑太保１０和３０倍稀释液竹腔注射防治该虫，３０ｄ后校正死亡率达９４．９７％。
Schizotetranychus nangingensis Ma et Yuan did heavy damages to the bamboo in Fujian Province and the damages were heavier in high temperature and dry season in July and August. The leaves of damaged bamboo plants were fallen and dying out. The dormant time of the mite was early November every year and terminated hibernation in late Feb. next year and began laying eggs in early March. The sex ratio of males to females of the mite was 13 1∶1. The effecacy reached to 94 97% 30 days after injection of 50% methamidophos, 40% omethoate, 20% fenvalerate, 20% methomyl and 50% chlorfluazuron diluted by 30 or 10 times into the bamboo carities.
