赤眼蜂防治农林害虫效果好、成本低,且无污染,是生防中重要方法之一。但1984年曾有人对其防治松毛虫效果提出异议。在对赤眼蜂防治方法作了大量调查研究后,得出赤眼蜂对防治松毛虫、黄刺蛾、杨小舟蛾、天幕毛虫等有显著效果的结论。防效的好坏决定于繁蜂质量、释放时机、放蜂数量等。 Trichogramma is effective in controlling pests of agriculture and forestry, low in cost, and non-polluting. It is one of the important methods in biological defense. However, in 1984, some people raised their objections to the prevention and control of the effect of pine caterpillars.
