农作物病虫害生物防治技术研究
摘 要
本文探讨农作物病虫害生物防治技术的各个方面，旨在为该领域的进一步研究和应用提供理论支持和实践指导。介绍天敌防治、微生物防治和植物性农药防治三种主要技术。天敌防治技术利用自然界中的天敌昆虫、捕食性螨类等生物，通过食物链关系控制害虫数量；微生物防治技术则利用细菌、真菌、病毒等微生物制剂，通过感染、寄生等方式杀灭或抑制病虫害；植物性农药防治技术则挖掘植物源活性成分，开发新型绿色农药，为农作物提供安全有效的保护。这些技术在实际应用中均取得了显著成效，为农作物病虫害防控提供了新的思路和方法。针对当前生物防治技术面临的挑战，提出了技术创新、生态环境调控、政策支持与产业发展以及农民培训与意识提升等多方面的优化策略。

RESEARCH ON BIOLOGICAL CONTROL TECHNOLOGY OF CROP INSECT PESTS
ABSTRACT
This paper explores various aspects of biological control technology of crop pests, aiming to provide theoretical support and practical guidance for further research and application in this field. Three main techniques of natural enemy control, microbial control and plant pesticide control were introduced. Natural enemy control techniques use natural insects and prey mites to control the number of pests through the food chain; microbial control techniques use bacteria, fungi and viruses to kill or suppress diseases and insect pests through infection and parasitic; plant pesticide control techniques excavate plant active ingredients and develop new green pesticides to provide safe and effective protection for crops. These technologies have achieved remarkable results in practical application, providing new ideas and methods for the prevention and control of crop diseases and insect pests. In view of the current challenges of biological control technology, the optimization strategies of technological innovation, ecological environment regulation, policy support and industrial development, and farmer training and awareness promotion are put forward.
