Abstract: The artificial release of Trichogramma is inefficient, making it difficult to utilize efficiently in a large area, and there are still problems, such as omission and uneven coverage. In recent years, in order to solve these problems and develop mechanized delivery technology, a lot of exploration has been carried out. This paper summarizes the development status of Trichogramma release technology at home and abroad, and compares and analyzes several existing main protection measures for Trichogramma eggs and related release machinery. Combining with the application of Trichogramma release machinery in China, this paper points out that the relevant research on Trichogramma delivery technology in China is insufficient, and the application of Trichogramma delivery machinery is immature, Intelligent operation and other directions are also prospected, aiming to provide a reference for better research on mechanized Trichogramma release.

Key words: biological control, Trichogramma, release machinery, precise delivery

摘要： 赤眼蜂人工投放效率低，时效性差，难以满足大面积防治的需求，且容易出现漏防、覆盖不均匀等问题。为解决上述难题，进一步推进赤眼蜂机械化投放技术，综述国内外赤眼蜂投放技术的发展状况，对比分析现有的几种主要的赤眼蜂卵的保护措施以及相关投放机械。结合我国赤眼蜂防治技术的应用情况，指出我国赤眼蜂投放技术的相关研究单一、赤眼蜂投放机械的应用不成熟等问题，并对赤眼蜂投放技术在机械创新设计、精准投放、智能作业等方向进行展望，旨在为更好地实现机械化投放赤眼蜂提供参考。
