摘　　要：为揭示桔小实蝇在云南镇康的种群动态特征,制定其防治对策,于2007—2008年在该地区通过性诱剂诱捕,对桔小实蝇种群动态进行了全年监测,并就气象因子及寄主植物对种群数量变动的影响进行了综合分析。结果显示:桔小实蝇在镇康全年发生,冬季种群数量较低,夏季种群数量高,且种群增长呈单峰型,高峰期出现在6月或7月。相关分析表明,月平均温度、月平均最低温度、月降雨量和日照数等是影响桔小实蝇种群数量变化的主要气象因子。当地寄主种类多,种植面积大,挂果时间长,为桔小实蝇提供了丰富的食物资源,是桔小实蝇种群数量变动的重要原因之一。The population dynamics of Bactrocera dorsalis was annually monitored by using sex induction agents to reveal its population dynamic characteristics and study the effect of meteorological factors and host plants on its population quantity change for drawing up countermeasures to control Bactrocera dorsalis during 2007-2008 in Zhenkang,Yunnan.The results showed that Bactrocera dorsalis occurred all year in Zhenkang,the population quantity was lower in winter and higher in summer,the population increment was a single peak type,and the population peak was in June or July.The relative analysis showed that monthly mean temperature,monthly mean minimum temperature,monthly rainfall and monthly sunlight hours were the crucial meteorological factors influencing the population fluctuation,and abundant host fruit species with big planting area and long fruiting period was one of the important factors affecting the population fluctuation which provided abundant food resource for Bactrocera dorsalis.
