 ABSTRACT

The oriental fruit fly, Bactrocera dorsalis, is one of the most destructive pests of mango production in Senegal. The aim of this study was to evaluate the effect of four mango varieties on the oviposition preference of  B. dorsalis at immature stage according to three physiological states of fruit. The oviposition preference was evaluated in choice and no-choice tests at laboratory conditions. This study showed that B. dorsalis is able to infest immature mangoes freshly harvest and those kept for 7 or 15 days after harvesting. Further, the variety and physiological state of the fruit influenced significantly the oviposition preference of this pest. In choice and no-choice tests, Kent proved to be the most preferred variety and Séwé the least preferred by B. dorsalis. Our results indicate also that B. dorsalis prefer to lay egg on fruits that kept for 15 and 7 days after harvest than those freshly harvest regardless of the variety in both experimental conditions. 

Keywords: Bactrocera dorsalis, Immature mangoes, Oviposition preference, Mango varieties.
