| Abstract: | The resources of natural enemies against tobacco pests were investigated in Chenzhou, Hunan, during 2005-2006. More than 70 species of natural enemies were found, among which 46 species were identified, including 7 species of parasitic natural enemies and 39 species of predacious ones. During the peak time, the highest parasitic rate of Aphidius gifuensis Ashmead was 40.3% in the field, and the highest rate of Campoletis chlorideae Uchida parasitizing Helicoverpa assulta Guenée and H. armigera Hübner was 75.0% in the field, while that of C. chlorideae parasitizing H. assulta and H. armigera on yellow flower tobacco 93 1 was 90.5% in 2006. It is evident that the natural enemies play a role in controlling tobacco pests. |
