This paper discussed and summarized the parasitic characters and the protection and utilization of 7 species of dominant natural enemies of sugarcane pests in Yunnan, China. Sugarcane pests are numerous and there are rich natural enemy resources in Yunnan sugarcane areas. There are more than 283 species of natural enemies against sugarcane pests in Yunnan, among which the dominant natural enemies with protection and utilization value and research significance include Trichograrrurui, Apantdes flavipes (Cameron) and Stumuopsis inferem Townsend parasitic: on sugarcane borers, Synonycfm grandis (Thunberg) , Lemtlia biplagiata ( Swartz) , Chilornenes sexnmaculata ( Fabricius) and Thiallela sp catching and feeding on Ceralovacima hunger a Zehntner, and Euborellia pallipes Shiraki preying on Saccharicocus sacchari (Cocherell) , Dysmicoccus bohinsis Kuw, Trochorhopalus hurneralis Chevrolat and Diocalruulra sp. There is also one fungal parasite, namely Becuweria bassiana, which is widely distributed in nature, and can parasitize in a variety of sugarcane pests including sugarcane borers, Exoloniha ser-ruhila (Gyllenhal) , Alissonolum impressicolle Arrow, T. hurneralis and Otidognathus rubriceps Chevrola. It has a natural parasitism rate generally around 10% and certain natural inhibition effect on sugircane pests. Reasonably protecting and utilizing natural enemies and giving full play to the natural regulation of natural enemies on pests are of great significance for protecting the ecological environment, maintaining the ecological balance of sugarcane fields, improving the comprehensive management level of pests, and protnoting the sustainable development of sugir industry.
