| 摘 要： | 调查了松幽天牛(Asemum amurense)在余姚地区的发生情况及其幼虫在枯死松树根内的分布规律。结果表明,松幽天牛在余姚地区1年发生1代,以幼虫在松树根内越冬。4月中旬开始化蛹,5月中旬成虫开始羽化,6月上旬成虫开始产卵,7月下旬卵开始孵化。松幽天牛在余姚地区的平均危害率达42.9%,其发生与土壤理化性质密切相关。松幽天牛幼虫在主、侧根内的分布数量差异显著,主根内的幼虫数显著多于侧根内。还依据松幽天牛的生活学特性提出了松幽天牛的防治措施

| Abstract: | Investigations were conducted on occurrence of Asemum amurenne in Yuyao,Zhejiang province and its distribution in the root of dead pine trees.The results showed that there is one generation a year of A.amureune in Yuyao,and overwinteres with larva in pine roots.The larva begins to pupate in mid-April.Adults emerge in Mid-May and lay eggs in early June.Eggs begin to hatch in late July.The average damage rate of A.amurense in Yuyao is 42.9%,and the occurrence is related closely with the physical and chemical ... |
