چکیده
The management of the biological control against Aphids by Parasitoids requires a deep knowledge of the specific diversity of target insect in the target area, and understanding the interactions between pests and parasitoids within temporal variations. Using a shaking method to collect the specimen of Aphids and their parasitoids on fruits orchard multi-species of Apple, Pear, Peach and Apricot trees. From April 2022 to October 2023. We first evaluate the population dynamics of Aphids and their Hymenopteran parasitoid. Secondly, we investigated temporal effect on the degree of trophic specialization. We report that the Parasitoids Lysiphlebus testaceipes was polypahagous and generalist for the most Aphid species on studied trees but it presented a preference to Aphis pomi and Dysaphis plantaginea on Apple trees within the optimal season. The Parasitoid Diaeretiella rapae can be the specific agent for biological control against Myzus persicae on Peach trees.
The study showed an important presence of the Secondary Parasitoids species on Apple and Peach trees that can affect parasitoid efficiency to control aphids.
