摘    要:为探讨混交林中松树对害虫的生态调控作用机制,研究了不同林分类型下马尾松林和湿地松林对马尾松毛虫生长发育的影响。结果表明,取食马尾松针叶的马尾松毛虫与取食湿地松针叶的相比,其发育历期缩短,死亡率降低,幼虫及蛹(雌、雄)重增加,化蛹率、羽化率和产卵量均提高;且其幼虫的代谢量(取食量与排泄量)更大,对食物的利用与消耗的各项指标均高。取食不同林分类型下的同一种松树(马尾松或湿地松)针叶的马尾松毛虫,以取食纯林松针的幼虫生长发育更快,死亡率更低,化蛹率、羽化率和产卵量更高,对食物的利用、转化和消耗率更强。混交林中的松针不利于马尾松毛虫的生长发育和种群增长。

关 键 词:马尾松毛虫    生长发育    松针    林相

Abstract:The growth and development of the massonpine caterpillar, Dendrolimus punctatus Walker was measured after being fed on pine needles from massonpine and slash pine in different pine forests. Shorter developmental period, higher mortality, greater pupation rate, emergence and fecundity were observed in pine caterpillars fed on massonpine needles compared to those fed on slash pine needles. Also, the food consumption and utilization of pine caterpillars fed on massonpine needles were higher than those fed on slash pine needles. Massonpine caterpillars had greater potential to improve their growth and development and enhance their fecundity and feeding efficiency when fed on massonpine needles or slash pine needles from pure pine forest compared to those fed on needles from mixed pine forest. Moreover, the management implications for pine caterpillars of mixed pine forest are discussed.
Keywords:Dendrolimus punctatus  growth  forest type  pine needles
