防治红檵木天牛及花叶病近年来，随着城市绿化事业的不断发展，红檵木作为彩色树种，在城市绿化中占有越来越重要地位。然而，由于绿化维护管理方面存在一些薄弱环节，我们经常看见一株株冠径1米多的红檵木整株死亡，严重影响了绿地景观效果。去年11月份，我们对红檵木死亡原因进行了研究，纠正了以前曾采取的不正确处理方法。一、虫害：经过对圃里濒临死亡的大规格红檵木挖开根部仔细观察，发现主要是蛀干类害虫星天牛的为害。1、为害方式：以幼虫在树基环状剥皮，最后蛀入木质部，由于苗木的韧皮部遭到破坏，致使水分和养分传输受阻，渐渐部分死亡，最后发展为整株死亡。2、幼虫形态特征：前胸后端有“凸”形纹，其前还有一对飞鸟形纹。3、防治方法：1．5至6月份捕捉成虫。2．成虫活动期，用塑料片包扎树基，防止其产卵。3．用80％敌敌畏乳剂或40％乐果乳油加水及黄泥拌成糊状，涂刷树基。4．钩杀幼虫，可塞入药棉，用泥封住。二、红檵木花叶病1、为害症状：首先表现为叶脉失绿，接着是叶片上呈轻微的斑驳状，以后成为深浅红斑驳状。新叶上症状更为明显。2、发病规律：此病毒病多由蚜虫传播。另外，红檵木多由扦插繁殖，扦插材料若带有病毒，也是导致病害的直接原因。3、防治办法：灭蚜对红檵木花叶病有一定控制作用，另外，红檵木多实行扦插繁殖，由于病毒的积累，到一定程度显现出来。因此，选择健壮的枝条进行扦插，也是防病的关键。不管怎样，注意田间的卫生管理，根除病株，清除CMV的其他寄主，以减少浸染源，是最主要的防治方法。（来源：中国花卉报2003-06-19）
