摘　　要：【目的】明确广西蔗区金龟子种类、分布及为害情况,提出综合防治策略,为甘蔗金龟子的防治提供理论依据和技术指导。【方法】在广西甘蔗种植区进行挖土调查,结合灯诱、标本及文献记载,对广西甘蔗金龟子的发生种类、分布及为害情况进行统计。【结果】为害广西甘蔗的金龟子有3科39种,其中鳃金龟科(Melolonthidae)21种,丽金龟科(Rutelidae)13种,犀金龟科(Dynastidae)5种。各蔗区金龟子优势种不同,多数地区混合发生。【建议】采取以农业防治为基础,灯光诱杀等物理措施为重点,结合绿僵菌、白僵菌等生物防治措施,必要时施用高效低毒低残留化学农药的综合防控策略,以达到长期控制金龟子种群的目的。【Objective】The species, distribition, damage of cockchafer in Guangxi sugarcane planting areas were studied to formulate comprehensive control strategy, in order to ensure sustainable development of Guangxi sugarcane industry. 【Method】The species, distribition and damages of cockchafer were investigated in Guangxi sugarcane planting areas by combining soil-scraping with light traps, specimens and documentary records. 【Result】There were 39 species belonging to 3 families of Scarabaeoidea on Guangxi sugarcane planting areas, including 21 species belonging to Mlolonthidae, 13 species belonging to Rutelidae, 5 species belonging to Dynastidae. In addition, the dominant species were different in various regions, and co-occured in most areas. 【Suggestion 】In order to control cockchafer sustainably, it is suggested that the comprehensive control strategy should be taken as base on agricultural control, and focusing on physical control such as light trap etc., combining with biological control of green and white muscardine fungus, furthermore, the high-efficient and low-toxicity and low-residue chemical pesticide should be used during critical periods.
