| 摘 要： | 对松纵坑切梢小蠢生物学特性、发生与为害同生态因子的关系和综合防治措施进行了系统研究,结果表明：松纵坑切梢小蠹在辽阳地区1a1代,为害长达240d以上。20a生以下中幼林的被害指数几乎是35a生以上林龄的2倍;混交林的被害指数是油松纯林的2．7倍;郁闭度0．5以下林分的被害指数是0．7以上的2．5倍;南坡、林缘的被害指数分别是北坡、林内的2．4倍和2．8倍,中上层（第四轮枝层以上）被害较重;树冠南部稍被害重于北部。采取营林措施、林问饵木诱杀、聚集信息素诱杀、根部喷施200倍绿色威雷和1,5％对硫磷粉剂、磷化铝12g·m^-3饵木熏蒸等防治措施,防治效果良好。

| Abstract: | A systematical study was conducted on biological characteristics of Tomicus piniperda and the relationship between the occurrence and ecological factors as well as comprehensive control measures.The results show that Tomicus piniperda has one generation per year in Liaoyang region,Liaoning Province, China,and damage period lasts more than 240 days.Infestation index of young-middle aged forest at age less than 20 years was almost 2 times that of 35-year-old forest,while the infestation index of the mixed for... |
