摘要
本文针对林业害虫天敌资源的可持续利用问题,通过文献研究、实地调查和案例分析等方法,系统探讨了林业害虫天敌资源的利用现状及应用策略。研究发现,我国林业害虫天敌资源丰富,但在实际应用中存在天敌资源筛选不精准、繁育技术不成熟、释放效果不稳定等问题。针对这些问题,提出了基于生态位适应性的天敌物种筛选方法,建立了温度、湿度和食物供给精准调控的规模化繁育技术体系,构建了"预测-监测-释放-评估"的天敌资源应用模式。同时,从技术创新、推广模式、生态安全和产业化发展等方面提出了系统的应用策略。研究表明,该应用模式在松毛虫、舟蛾等重大林业害虫防治中取得显著成效,平均防治效果达85%以上,经济效益提升40%,为林业害虫生物防治提供了可推广的技术方案和实践经验。
This article focuses on the sustainable utilization of natural enemy resources of forestry pests.Through literature research,field investigations,and case analysis,the current status and application strategies of natural enemy resources of forestry pests are systematically explored.Research has found that China has abundant natural enemy resources for forestry pests,but in practical applications,there are problems such as inaccurate screening of natural enemy resources,immature breeding techniques,and unstable release effects.In response to these issues,a natural enemy species screening method based on ecological niche adaptability has been proposed,and a large-scale breeding technology system for precise regulation of temperature,humidity,and food supply has been established.A natural enemy resource application model of"prediction monitoring release evaluation"has been constructed.Provided scalable technical solutions and practical experience for biological control of forestry pests.
