| 摘 要： | 云南松毛虫是福建省柳杉的严重害虫。该虫一年发生一代,以卵越冬,卵于翌年一月中旬孵化,幼虫七龄,历期133—174天,蛹期64—79天,成虫寿命5—12天。其发生发展与林分的林木组成,气候、天敌等因子密切相关。用2.5％溴氰菊酯乳油,50％甲胺磷乳油,90％敌百虫晶体防治幼虫,有良好效果。

| Abstract: | Dendrolimus houi Lajonquiere is a serious pest of the Cryptomeria (Cryptomeria fortunei Hooibrenk) in Fujian Province. The pest has one generation per year and overwinters as eggs. The eggs hatch in mid-January next year. Seven larval instars have been observed, and the larval development lasts 133-174 days. The pupal stage lasts 64-79 days. The adults live for 5-12 days.The damage is closely related to the composition of stand , climate and natural enemies.The effective measures to control the larvae are spraying with 2.5% Decamethrin, 50% Methamidophos or 90% Dipterex. |
