摘要
苹果巢蛾为害苹果等多种果树叶片 ,幼虫吐丝将叶片做成网巢为害 ,大发生时整株叶片食光 ,严重影响果树结实 ,甚至造成整株死亡。该虫一年一代 ,以一龄幼虫在卵鞘内越夏、越冬。幼虫 5月中旬为害盛期 ,用 80 %敌敌畏 1∶ 150 0、 2 .5%敌杀死 1∶ 2 0 0 0 ,防治效果达
Hyponomeuta malinella Zeller, whose larvae spinned nest of net at leaves, damaged leaves of many fruit tree species such as apple tree leaves. All leaves of fruit trees were eaten up when the pest was epidemic. Thus the quantity of fruit-bearing was influenced seriously, even the whole tree was damaged to die. The pest, whose larvae of one instar wintered and summered in egg-case, completed one generation in one year. Over 96 percent of larvae could be killed by spraying DDVP of 80 percent (1:1500) or dipterex of 2.5 percent (1:2000) in the middle of May when the larvae was in rampant stage.
