Contribution to the study of citrus thrips

Thrips are considered pests of citrus fruits so it is important to study the different species of thrips that feed on the Citrus genus in the major citrus-growing areas of Algeria.The population dynamics of thrips depend on several abiotic and biotic factors including temperature rainfall and the presence of beneficial organisms. Their evolution is unstable due to climatic conditions and landscape structure.In order to ensure good orchard management and preserve biodiversity it is important to use biological control in its various forms.
