摘要
2009—2011年在广东汕头市及汕头市南澳岛使用桔小实蝇诱剂(Methyl eugenol)监测桔小实蝇种群的动态数量。结果表明,汕头市桔小实蝇为害极为严重,桔小实蝇一年四季均有成虫活动,每年在7—8月份有一个种群动态数量高峰期;同一地点每年桔小实蝇种群动态数量高峰的出现时间受当年天气温度、雨季早晚、雨量和监测点周围生态环境等因素的影响而稍为提前或推后。
The population dynamics of the oriental fruit fly Bactrocera dorsalis （Hendel） （Diptera：Tephritidae）through methyl eugenol-baited traps in were monitored he Shantou City of Guang- dong Province flom the year 2009 to 2011. The results indicated that the dam- ages of oriental fruit fly were extremely serious in the Shantou Cify, and the ori- ental fruit fly occurred all year round in the Shantou City. Usually, its peak was in July to August of every year. The number of population dynamics of the oriental fruit fly at the same monitoring stations obviously differed every year, and was influenced by factors as temper- ature, rainfall and ecological environ- ment around monitoring stations.
