不同混交模式马尾松林与松墨天牛种群动态的关系

Relationship between Pinus massoniana with Different Mixed Forest Stand Mode and Population Dynamics of Monochamus alternates

通过调查马尾松纯林、马尾松×杉木混交林、马尾松×火力楠混交林、马尾松×毛竹混交林等5种混交比例模式的马尾松林中诱捕的松墨天牛数量,分析不同混交模式与松墨天牛种群动态的关系。结果表明:不同混交模式的马尾松林诱捕到的松墨天牛成虫数量有差异,马尾松混交林诱捕到松墨天牛成虫数量明显低于马尾松纯林。每年6月和8月为华安县松墨天牛成虫活动的高峰期,应结合生产实际开展松墨天牛综合防控。

The quantities of Monochamus alternatus adults had been investigated by APF- Ⅰ sawyer trap s, which were conducted in pure P. massoniana stand, P. massoniana×Cunninghamia lanceolata stand, P. massoniana×Michelia macclurel stand and P. massoniana×Phyllostachys heterocycla stand. We had analyzed the relationship between P. massoniana stand with different mixed mode and population dynamics of M. alternatus. The results showed that, there were differences between the sawyer adult quantities strapped by APF- Ⅰ sawyer traps in different mixed mode of pine stand, of which those trapped in the mixed forest stands were significantly lower than those in the pure stand. There were two activity peaks of adults in June and August every year in Hua＇an Country, and comprehensive measures should be taken to prevent and control the pest.
