Population dynamics studies are very important for any area-wide control program as they provide detailed knowledge about the relationship of Medfly [Ceratitis capitata (Wiedemann)] life cycle with host availability and abundance. The main goal of this study is to analyse seasonality of C. capitata in Terceira and Sao Jorge Islands (Azores archipelago) using field and laboratory data collected during (2010-2014) CABMEDMAC (MAC/3/A163) project. The results from Sao Jorge Island indicate significantly lower male/female ratio than on Terceira Island. This is an important finding specially regarding when stablishing the scenario parameters for a sterile insect technique application in each island. The population dynamics of C. capitata are generally linked with host fruit availability and abundance. However, on Terceira Island fruit infestation levels are not synchronized with the trap counts. For example, there was Medfly infestations in some fruits [e.g., Solanum mauritianum (Scop.)] while in the nearby traps there were no captures at the same time. From this perspective, it is important to denote the importance of wild invasive plants, on the population dynamics of C. capitata, as well important to consider the possibility of having different densities of traps according to the characteristics of each area in order to improve the network of traps surveillance's sensitivity on Terceira Island.
种群动态研究对于任何区域控制计划都非常重要,因为它们提供了关于地中海实蝇[Ceratitis capitata (Wiedemann)]生命周期与寄主可获得性和丰度之间关系的详细知识。本研究的主要目标是利用在(2010 - 2014年)CABMEDMAC(MAC/3/A163)项目期间收集的田间和实验室数据,分析亚速尔群岛特塞拉岛和圣若热岛的地中海实蝇季节性。圣若热岛的结果表明,其雌雄比例显著低于特塞拉岛。这是一个重要发现,特别是在为每个岛屿制定无菌昆虫技术应用的情景参数时。地中海实蝇的种群动态通常与寄主果实的可获得性和丰度相关。然而,在特塞拉岛,果实侵染水平与诱捕计数不同步。例如,在一些果实[如Solanum mauritianum (Scop.)]中有地中海实蝇侵染,而在附近的诱捕器中同时却没有捕获到实蝇。从这个角度来看,必须指出野生入侵植物在地中海实蝇种群动态中的重要性,同时考虑根据每个区域的特点设置不同密度诱捕器的可能性,以提高特塞拉岛诱捕器监测网络的灵敏度也很重要。
