浅谈“以虫治虫”天牛生物防治技术在金坛地区的应用

Discussion on the Application of “Eliminating Pests with Pests” Longicorn Biological Prevention and Control Technology in Jintan Area

摘要: 近年来，天牛虫害在金坛地区的发生率较高、危害较严重，部分道路行道树发生率甚至达到100%。天牛不仅是防治最困难的植物慢性毁灭性害虫之一，且形成的蛀干对行人、交通安全等存在严重威胁。针对受天牛危害的园林树木，化学防治是目前主要的防治方法，但其有易残留、易产生抗药性、易污染环境、成本高等缺点，因此，生物防治越来越受到人们的欢迎。本文主要介绍金坛地区应用“以虫治虫”生物防治技术取得的一些成效。

Abstract: Longicorn insect attack has shown a high incidence rate and caused a dangerous result in Jintan area in recent years, with the occurrence rate of border trees on some roads even reaching 100%. Longicorn is one of the destructive pests which devastate plants chronically and are difficult to be prevented and controlled. Besides, the tree bunk damaged by longicorn will severely threat the safety of pedestrian and transportation. Chemical control is the major prevention and control method used for the ornamental trees and shrubs damaged by longicorn. However, this method is easy to be residual, easy to generate resistance to drugs, easy to pollute the environment and costs higher. Therefore, biological prevention and control have been increasingly popular among people. This paper mainly introduces some effects achieved by the application of “eliminating pests with pests” biological prevention and control method in Jintan area.
