摘要
白蜡敛片叶蜂Tomostethus fraxini是近些年白蜡树上新发现的一种食叶害虫,调查发现该虫在北京1年发生1代,以老熟幼虫做茧在土中越冬,3月中旬开始化蛹,3月下旬出现成虫;成虫将卵产于叶片边缘,幼虫取食叶片,为害盛期为4月下旬至5月上旬.色板诱集试验表明,8种颜色粘虫板均可以诱集到成虫,深绿色、蓝色、黄色诱集效果较好,与其他5种颜色粘虫板达到显著性差异.本文对各虫态进行了描述,提供了彩色图片,讨论了该虫发生趋势.
Abstract
Tomostethus fraxini is a newly discovered leaf-eating pest on Fraxinus spp.in recent years.This sawfly has one generation per year and overwinters as matured larvae in soil.The overwintered larvae begin to pupate at mid-March and adults emerge at the end of March.The female adults lay eggs on the margin of leaf.The larvae feed on leaves and the peak period of damage is from end of April to early May.The trapping test shows that adults are attracted to all eight colors,and dark green,blue and yellow sticky board traps have better effect among them.The paper has described morphology of four stages,provided with color pictures for adult,larvae,pupa,eggs,and discussed its occurrence tendency.
