摘要
2006～2008年在永州市农科所、宁远县对烟草害虫天敌种类进行了调查,共发现烟草害虫天敌3个纲10个目51个种,烟青虫(棉铃虫)寄生率为41.2%～52.3%,最高达69.8%,斜纹夜蛾平均寄生率11.13%,最高达65.5%,两者均被"棉铃虫齿唇姬蜂"和"螟蛉悬茧姬蜂"寄生。
The resources of parasitic natural enemies for main tobacco pests were investigated by Yongzhou Institute of Agricultural Sciences from 2006 to 2008 in Ningyuan. The results showed that there were 3 classes, 10 orders and 51 species natural enemies for tobacco pests. The parasitic ratio of Heliothis assulta Guenee was 41.2%-52.3%, and the highest was 69.8%; the average parasitic ratio of Spodoptera litura Fabricius was 11.13%, and the highest was 65.5%; both of them were parasitized by Campoletis chlorideae Uchida and Charops bicolor Szepligeri.
