How much is aphid population dynamics affected by their natural enemies? An empirical example from Greece
By monitoring of 50 aphid colonies in 2017 and another 50 colonies in 2018 twice a week, we looked at how the aphid dynamics wasaffected by their natural enemies. This will help us to see, how much the presence of natural enemies shortens the duration of an aphidcolony, which may be one of the causes, why Harmonia axyridis is not very successful in the Mediterranean: the aphid colony may exist for aperiod of time too short in the Mediterranean conditions to enable successful development of H. axyridis.
