| 摘 要： | 核桃小吉丁虫是核桃树的主要害虫之一。在陕西商州区调查,有虫株率高达20-30%、严重的高达70%以上,主要危害核桃的枝条。幼虫蛀入1-3年生枝干皮层。枝条受害后,常表现枯梢,树冠变小,产量下降,甚至整株死亡。采用林业防治,生物防治,化学药剂防治等综合防治技术,防治效果显著。

| Abstract: | Agrilus lewisiellus Kere is one of the major pests attacking walnut trees. Investigation in Shangzhou showed that there are 20%-30% of walnut trees having the pests attacking, mainly attac- king trunks. Larva enters into one to three-years trunks which, after being infected, appeared dry, making the crown smaller and nut yield dropped. Integration of forest measure, biological measures and chemical approaches has had effective result for control. |
