摘要
核桃瘤蛾以幼虫食害核桃树叶,幼龄幼虫食害叶肉,留下网状叶脉,长大后能将全树叶片吃光,只剩下主、侧叶脉。当年7—8月危害最严重,可造成枝条二次发芽,致使树势极度衰弱,抗寒力下降,导致翌年大批枝条枯死,严重影响核桃树的产量和寿命。该文于2019—2022年对发生在驻马店的核桃瘤蛾进行观察记载和防控,效果良好,达到了防治目标。
Nola distributa eats the leaves of walnuts with its larvae,and the young larvae eat the mesophyll,leaving mesh veins.When they grow up,they can eat the whole tree leaves,leaving only the main and side veins.The most serious damage occurred from July to August,which could cause secondary sprouting of the branches,resulting in extreme weakness of the tree vigor and decline of cold resistance,leading to a large number of branches dying in the next year,which seriously affected the yield and life of walnut trees.From 2019 to 2022,the observation,recording and prevention and control of Nola distributa in Zhumadian were carried out.The effect was good and the control goal was achieved.
