摘    要:2002~2005年期间,在广东广州利用性引诱剂对桔小实蝇进行了全年种群动态监测,调查可知桔小实蝇可在广州全年发生.该虫数量从5月开始迅速上升,6~9月份是发生盛期;10月份虫口密度逐渐下降,11月到翌年3月份种群数量很低.对桔小实蝇发生数量和气象因子进行主成分分析和相关分析,结果表明温雨因子作用最大,其中月平均降雨量是影响桔小实蝇种群变动的关键因子;日照因子作用次之,但月总日照时数对该虫的发生数量没有显著影响.

Abstract:The population dynamics of Bactrocera dorsalis (Hendel) was monitored with pheromone methyl eugenol traps all year around from 2002 to 2005 in Guangzhou, Guangdong province. Investigation showed that B. dorsalis occurs all year round in Guangzhou. The population increased from May rapidly. The population decreased gradually from October. Afterwards, the population remained low from November to March of the next year. The climate factors which influence the population fluctuation of B. dorsalis were analyzed by principal component analysis and correlation analysis. The result showed that the temperature-rainfall factor is the main influence, and monthly mean rainfall is the key factor which influence the population fluctuation of B. dorsalis; the sunlight hours factor is the secondary influence, but it has no obvious relevance with the monthly mean amounts of B. dorsalis.
