Abstract(s)
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
