摘  要：
【目的】揭示兴义桔小实蝇种群动态及与影响因素间的关系,了解其在特定区域内的发生、发展规律,为桔小实蝇的监测和防控提供科学指导。【方法】2012~2013年,在贵州兴义混合果园采用桔小实蝇专用雄性外激素进行全年诱捕,对当地桔小实蝇种群动态进行监测,并就寄主植物、主要气候因子对种群变动的影响进行综合分析。【结果】桔小实蝇在兴义常年发生,年度间无差异(F=0.013,P=0.911);1~4月桔小实蝇种群数量较低,5月开始迅速上升,于7~9月形成种群高峰,最高的2013年9月平均每个诱捕器诱捕到1861头,10月种群数量迅速下降,至年底仍能稳定诱捕到桔小实蝇。结合生物统计软件综合分析表明,温度、降雨、平均水汽压和寄主植物是影响桔小实蝇种群变动的主要因素。【结论】桔小实蝇种群在兴义的年度变动受寄主植物和温度、降雨、平均水汽压等环境因素的影响,各影响因素的作用方式、强度、影响方面和主要时间不同,各因素间也相互影响,这些作用和影响形成综合效应,共同塑造、形成了兴义桔小实蝇种群变动的基本模式。每年7~9月是兴义桔小实蝇自然种群数量最大的时期,生产上应密切关注此时的种群动态,并根据其危害情况及时采取必要的防治措施。

摘  要：
【Objective】The present experiment was conducted to investigate relation between population dynamics and effective factors of Bactrocera dorsalis(Hende1) in Xingyi city, in order to understand the law of occurrence and development and provide scientific guidance for monitoring and controlling it. 【Methods】using B. dorsalis as materials, they were trapped with special male pheromone(methyl eugenol) in mixed orchard of Xingyi, Guizhou province during 2012-2013.The population dynamics was monitored and its effects of host-plants and main meteorological factors were analyzed comprehensively. 【Result】B. dorsalis occured perennially in Xingyi city, and there was no difference between different years(F=0.013,P=0.911). The population quantity of B. dorsalis trapped was relatively lower during January-April, presented a tendency of straight climb in May, reached the peak(1816 in September 2013) during July-September, decreased in October, and remained stable at the end of the year. The software analysis showed that the temperature, rainfall and host plant had proven to be the main influences on the population dynamic of B. dorsalis. 【Conclusion】The population dynamic of B. dorsalis is influenced by the host plants, temperature, rainfall and average vapor pressure, etc. While all influence factors are different in mode, strength, effect and main time, influence each other, and form comprehensive effects and basic mode of population dynamic of B. dorsalis(Hende1) in Xingyi city. The fastigium of population quantity is from July to September each year. Therefore, during this period, the population dynamic should be seriously concerned to take preventive measures based on damage situation.
