摘　　要：2009年4-8月,在云南省新平县水塘镇南秀村和德宏州陇川县章凤镇小怕浪村甘蔗种植基地,调查分析了甘蔗玉米间作对甘蔗绵蚜Ceratovacuna lanigera Zehntner及捕食性瓢虫种群的影响。结果表明,甘蔗净种田与间作田绵蚜的虫情指数变化趋势一致,但净种田绵蚜虫情指数显著高于间作田（新平：F=55.43,P〈0.01;陇川：F=57.11,P〈0.01）。净种田与间作田瓢虫虫口密度变化趋势一致,均呈单峰型变化。其中间作田瓢虫虫口密度显著高于净种田（新平：F=21.42,P〈0.01;陇川：F=69.55,P〈0.01）,表明间作田中捕食性瓢虫在甘蔗绵蚜种群控制中发挥着重要的作用。Study on the effect of intercrop of sugarcane with maize on the aphid population and the population of predatory coccinellidae was conducted in Xinping country and Longchuan country in Yunnan from April to August,2009.Results showed that the insect index of aphid on sugarcane plants in intercropping field was significantly lower than that of in the monoculture field（Xinping：F=55.43,P0.01;Longchuan：F=57.11,P0.01）,though the population dynamics similar.The population of the predatory coccinellidae in the intercropping field was significantly higher than that in the sugarcane monoculture field（Xinping：F=21.42,P0.01;Longchuan：F=69.55,P0.01）,even though the population dynamics of was similar in the sugarcane monoculture and intercropping field,and the population of predatory coccinellidae showed one peak.The higher population of predatory coccinellidae played an important role in the population control of aphid on sugarcane plants.
