摘要

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 Trichogramma, Apanteles flavipes(Cameron) and Sturmiopsis inferens Townsend parasitic on sugarcane borers, Synonycha grandis(Thunberg), Lemnia biplagiata(Swartz), Chilomenes sexmaculata(Fabricius) and Thiallela sp catching and feeding on Ceratovacuna lanigera Zehntner, and Euborellia pallipes Shiraki preying on Saccharicocus sacchari(Cocherell), Dysmicoccus bohinsis Kuw, Trochorhopalus humeralis Chevrolat and Diocalandra sp. There is also one fungal parasite, namely Beauveria bassiana, which is widely distributed in nature, and can parasitize in a variety of sugarcane pests including sugarcane borers, Exolontha serrulata(Gyllenhal), Alissonotum impressicolle Arrow, T. humeralis and Otidognathus rubriceps Chevrola. It has a natural parasitism rate generally around 10% and certain natural inhibition effect on sugarcane 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 promoting the sustainable development of sugar industry.
