摘要
2014-2017年在河北省采用室内饲养结合野外观察的方法总结危害杏树Armeniaca vulgaris Lam.和蒙古栎Quercus mongolica枝干的天牛科害虫——圆尾弧胫天牛Callimus(Nathriopterus)shensiensis(Gressitt, 195l)的形态学特征和生物学特性。该虫在河北承德1 a 1代,以老熟幼虫在寄主植物木质部蛀道末端越冬,翌年4月上旬开始陆续化蛹,成虫5月上旬开始羽化,盛期在5月中下旬。并据此提出防治建议。
The method of indoor feeding and field observation were adopted in Hebei Province from 2014 to 2017 to observe and summarize the morphological and biological characteristics of Callimus(Nathriopterus)shensiensis(Gressitt,195l),which attacked trunks and branches of Armeniaca vulgaris and Quercus mongolica.The insect had one generation each year in Chengde,Hebei Province,and the old larvae overwintered at the end of the xylem tunnel of the host plant.Pupation started from early April of the next year.The adults began to emerge in early May,and the peak period was in the middle and late May.Suggestions for prevention and control of the pest are proposed in the article.
