我今天修剪金银花时发现茎上长了好多白色的东西，不知道是不是长虫了？

介壳虫虫体外有蜡质壳，所以农药比较难杀死，
要用剧毒内吸型农药才能较好杀死
普通的菊酯类农药效果很差
我不敢用剧毒型的

上次版子里有人提到金银花的蚜虫，这次有有介壳虫，我这种懒人就更不敢种了

我今天已经仔细的用竹片刮过了，又打了药。应该消灭了吧

我今天又检查了昨天清除的地方，结果有大发现。好些虫都是躲在树皮下面，昨天根本就没伤到它们，害得我把好些树皮都扒了。我担心还是不彻底，怎么办啊。<img src="attachments/dvbbs/2005-3/2005310202842442.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-3/2005310202842442.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
