Abstract The response of wild Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) males to orange peel chemicals and their effect in mating competitiveness exposed these was studied the laboratory (25±2 °C, 65±5%, r.h.). Males were attracted, landed, arrested on ripe oranges that superficially wounded flavedo region peel, fed wounds. Exposure conferred a advantage over unexposed males. In flies 1 10 days age, this independent age during exposure lasted at least following exposure. Twenty‐four hours ensured effect. intact oranges, or covered with wire‐screen, which allowed olfactory landing screen but not direct contact fruit, did confer any advantage. Apparently, required order increase competitiveness. It is suggested acquisition certain substances flavedo, most probably through ingestion, responsible for observed phenomenon. Our findings are discussed relation sexual behaviour fly. Implications enhancement released sterile effectiveness Sterile Insect Technique programs as well.
