松阿扁叶蜂的生物学特性及综合防控措施

Biological Characteristics of Acantholyda posticalis Matsumura and Its Comprehensive Control Measures

松阿扁叶蜂是一种食叶类害虫,在阳泉市狮脑山林场1年发生1代,有滞育和世代重叠现象,羽化盛期在6月底至7月初,幼虫危害盛期在8月上中旬,严重时松针呈火烧状,树势衰弱,连续危害几年会导致树木死亡。根据松阿扁叶蜂的生物学特性和危害特点,总结出对生态环境安全、防治效果显著的综合防控措施。

Acantholyda posticalis Matsumura is a kind of leaf eating pest. It has one generation per year in Shinaoshan Forest Farm of Yangquan City, with the phenomenon of diapause and generation overlapping. Its peak of adult emergence period is from late June to early July, and the peak of larval damage period is in the early and middle of August. When the pests cause serious damage, the pine needles are fire-liked, the tree vigor is weak, and continuous damage for several years will lead to tree death. According to the biological characteristics and damage characters of Acantholyda posticalis Matsumura, the comprehensive control measures are summarized, which are safe to the ecological environment and have significant control effects.
