近年来,香蕉象鼻虫在蕉区发生为害严重。该虫以成虫和幼虫蛀食香蕉假茎,使假茎呈蜂巢状,蛀道纵横交错,叶片卷缩变黄,影响香蕉生长,甚至全株枯死。过去防治是剥除枯叶假茎后,用石灰浆加敌百虫涂茎或用敌敌畏兑水淋假茎。虽然取得一定效果,但药效不持久,且配药麻烦。1990年以来,经我们多次实践,总结出一种简单易行的防治新法。 In recent years, banana weevil banana serious damage. The worm to adults and larvae eating banana pseudostem, so that the pseudostem was honeycomb, criss-cross the tunnel, the leaves curl yellow, affecting the growth of bananas, and even the whole plant died. In the past, pest control was stripped of false stems, with lime mortar trichlorfon coated stems or diluted with dichlorvos watery pseudostems. Although achieved some results, but the efficacy is not lasting, and dispensing trouble. Since 1990, after many times of our practice, a simple and easy method of prevention and control has been summed up.
