木虱寄生蜂研发现状及趋势

木虱是木本植物上的重要害虫，严重为害柑橘、梨树和枸杞等果树，对果业生产造成极大威胁。木虱寄生蜂种类多，自然种群数量大，是木虱的重要自然控制因子，在多种木虱防治中发挥了极其重要的作用。当前，已经发现并记录的木虱寄生蜂近百种，但是能够人工大量扩繁的木虱寄生蜂只有几种。应该加强木虱寄生蜂的调查和研究，特别是重要木虱寄生蜂的人工扩繁技术的研究，为木虱的生物防治提供新的技术和产品。

Research Status and Prospect on the Parasitoids of Psyllids

Psyllids are important pests on woody plants, especially cause serious damage to fruit trees such as citrus, pear and wolfberry, and thus pose a great threat to fruit production. As an important natural control factor of psyllids, the parasitic wasps play an extremely important role in the management of psyllids. At present, nearly 100 species of parasitic wasps of psyllids have been discovered and recorded, but only a few species can be artificially propagated in large quantities. It is necessary to strengthen the investigation and research on the parasitic wasps of psyllids, especially the artificial propagation technology of important parasitic wasps, so as to provide new technologies and products for the biological control of psyllids.
