怎样防治介壳虫

Miss Chen

介壳虫是花卉中常见的害虫,常以口器插入枝、叶、果实组织中吸食汁液,造成枝、叶枯萎,甚至枯死。介壳虫繁殖较快,1年发生两代甚至几代,初生幼虫只爬行12天就逐渐停住吸食不动了。其抗药力强,一旦介壳或蜡质物形成,一般药剂难以进入,给防治工作带来困难。

常见介壳虫危害的花卉有:仙人掌、茶花、桂花、兰花、紫薇、海桐、牡丹、扶桑、佛手、茉莉、含笑、铁树、柑橘、月季等。其防治方法如下:
1、以防为主,凡外来的花卉(包括整株、球茎、插条等)一定要严格检查是否带有虫害,若有要及时除掉,并且隔离;



2、在花卉养护期间,发现叶、枝上有介壳虫,应及时处置。少量发生时,可用软毛刷轻轻刷下,把虫子集中起来烧毁,切勿乱扔,以免造成虫子“搬家”,到处蔓延扩散;

3、药剂防治,掌握喷药时期是关键,不论是哪种介壳虫,都应掌握在孵化期(即介壳形成前),用40%氧化乐果乳剂或50{bf}马拉硫磷或80{bf}敌敌畏1000倍液喷洒;

4、用清水冲洗,如君子兰等大叶的盆花,可以用肥皂水连续擦洗3~5次,这样也可清除介壳虫。
