| 摘 要： | 杉木甲螨（Podoribatessp．）是危害杉木的一种新害虫，该虫在浙江黄岩1年发生数代，卵、若螨、成螨3种虫态混合世代重叠，5月上旬～6月下旬及7月下旬～8月下旬有2次发生盛期，10月进入越冬，以成螨在杉木枝梢节叉处越冬，翌年5月初开始产卵。通过几种药剂试验，发现三唑锡1500倍液和1600倍液对甲螨有较好的防治效果，分别达100％和98％，综合效益，以水胺磷1500倍液更适合大面积林间防治。

| Abstract: | Podoribates sp. is a pest endangering Cuninghamia Ianceolata, which propagates several generations in one year in Huangyan of Zhejiang. Three forms, egg, yong mite and adult mite had overlaped generations. There were two high occurrence periods in one year. Podoribates sp.began to overwinter in top and node of branch in form of adult mite in octoble, In may of the next year, it begain to lay eggs. Test showed that 1 500 and 1 600 fold solutions of azocyclotin had better effectiveness; their mortality rates were 100% and 98%, respectively, and that 1 500 fold solution of isocarbophos is more suitable to prevent pest on large scale. |
