摘    要：為掌握贵阳市猕猴桃园桔小实蝇种群发生动态，找出影响种群动态变动的气象因子，为桔小实蝇的监测和防控提供科学指导。2017—2018年，在贵阳市主要猕猴桃基地猕猴桃园，采用Steiner诱捕器内添加桔小实蝇诱剂对桔小实蝇种群进行系统调查与监测，并对影响种群变动的主要气象因子进行分析。结果表明，1—6月，贵阳市猕猴桃园桔小实蝇种群发生数量较低， 7月中旬开始上升，8月中旬至10月为种群盛发期，11月开始急剧下降，12月种群逐渐消退。桔小实蝇种群数量的日变化与日平均气温、日最低气温相关性极显著，与日最高气温相关性显著。日平均气温、日最低气温、日最高气温、日降雨量对种群的影响比日平均相对湿度更直接。气温是影响桔小实蝇种群变动的主要因素，受气温、降雨量以及其他因素的综合影响，每年8月中旬至10月为贵阳市猕猴桃园桔小实蝇种群发生盛期，在8月下旬或9月中旬桔小实蝇种群数量达到最高峰。

Abstract： To grasp the population dynamics of Bactrocera dorsalis in Guiyang， find out the meteorological factors that affect the population dynamics， and provide scientific guidance for the monitoring and prevention of Bactrocera dorsalis. From 2017 to 2018， in the kiwi orchard of the main kiwi fruit base in Guiyang City， the Steiner trap was used to add the Bactrocera dorsalis attractant to systematically investigate and monitor the population of Bactrocera dorsalis， and the main meteorological factors affecting population changes Perform analysis. The results showed that， From January to June， the population of Bactrocera dorsalis in kiwifruit orchards in Guiyang City was relatively low. It began to increase in mid-July. The population peaked from mid-August to October. The population began to decline sharply in November and gradually decreased in December. Subside. The daily variation of Bactrocera dorsalis population has a very significant correlation with daily average temperature and daily minimum temperature， and significant correlation with daily maximum temperature. The daily average temperature， daily minimum temperature， daily maximum temperature， and daily rainfall have a more direct impact on the population than the daily average relative humidity. Temperature is the main factor affecting the population changes of Bactrocera dorsalis. Due to the comprehensive influence of temperature， rainfall and other factors， mid-August to October each year is the peak period for the population of Bactrocera dorsalis in kiwifruit orchards in Guiyang. The population of Bactrocera dorsalis reached its highest peak in late August or mid-September.
