摘要: 通过对1992~2001年5种不同混交林型的马尾松林内各代幼虫发生量,受害面积和有虫株率的系统调查,研究了各种不同林型的松林对马尾松毛虫种群动态的影响。结果表明,不同树种混交的马尾松林对马尾松毛虫的种群动态有较大的影响。马尾松毛虫在马尾松纯林中发生量多,为害最严重,暴发周期最短;在与杉木等混交的马尾松林中发生次之;而在与阔叶树混交的马尾松林中平均每株虫口数少,发生与危害率及有虫株率均较其它林型小,不易引起松毛虫暴发为害。

Abstract: The population dynamics of Dendrolimus punctatus was analyzed by investigation of the larva occurrence numbers,damaged area and percent of trees with larva in five different pine forest from 1992 to 2001.The results showed that the greatest larva numbers,highest infest,and shortest outbreak period of D.punctatus were occurred in pure pine forest,while less in the mixed pine forest with cedar,and the least in the mixed pine forest with broad-leaved trees.
