德国农作物病虫害种类及其生物防治研究

The Species and The Research Status of Bio-control of Plant Pests in Germany

摘要:

本文概述了德国的玉米、麦类、马铃薯、甜菜和十字花科作物上的主要病虫害种类及发生为害情况。对德国小麦病虫害研究内容和手段。以小麦为主的病虫害计算机模型研究。与作物育种相结合的病虫害抗性研究和植物保护机械作了阐述。介绍了德国害虫生物防治研究的方向,利用赤眼蜂防治害虫的种类,繁蜂和田间释放技术,其他天敌的繁殖利用和农药对天敌的副作用等方面的研究情况。

Abstract:

The important diseases and insects on maize,cereals,patato,sugar-beet andcruciferous crop and their occurrence in Germany are described. The research status on cereal insects and diseases,computer modelling of winter wheat eco-system,plant resistance,and sprayer in Germany are illustrated. The research status of biological control, massrearing and field application of Trichogramma and other beneficial insects,and the effectsof insecticides on beneficial arthropoda in Germany are introduced.
