摘要
栗蛀花麦蛾是我国首次记录的粟树花期发生的一种新害虫,在河北省燕山栗区发生普遍.为害严重.以幼虫蛀害雄花和混合花序雌花,引起整个混合花序脱落而减产;1年发生1代,以蛹在树皮裂缝、翘皮下做茧越冬;幼虫为害盛期为6月中下旬.利用花期喷药或刮树皮可有效地控制为害.
The present paper deals with a study on bionomies of Stenolechia rectivalva Kanazawa.It was a new important insect pest on flower of chestnut trees,and was first discovered inChina.In Hebei Province this insect was the most injurious and abundant in the chestnutproducing districts of Yan-mountain area.The larvae bored into and damaged the male flow-er or female flower of mixed inflorescence,which may became withered and fell,leading tosever yield reduction.This insect propagates one generation per year,passes through thewinter as a pupa inside a silken cocoon under bark crevice or loose barks.Larvae is fed inflower from early to middle of June.Chemical control applied on blossom period of male in-florescence and stripped the barks are considered as the most effective ways to control thisinsect.
