This study investigates the insecticide resistance profile of a field strain of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), in Egypt. Through laboratory bioassays and molecular analysis, the research examines the susceptibility of the field strain to commonly used insecticides and elucidates the underlying mechanisms of resistance. Results provide valuable insights into the current status of insecticide resistance in Ceratitis capitata populations in Egypt, informing pest management strategies and facilitating the development of sustainable control measures.
