The Mediterranean fruit fly, Ceratitis capitata Wied, laboratory investigations of its reproductive behaviour in Coffea arabica in Kenya
Adults of Ceratitis capitata, bred our of ripe berries, were maintained on honey-water in the laboratory. In a choise experiment, with berries of different stages of development presented for oviposition, females preferred ripe berries just before they turned completely red. They did, however, oviposit in green and red berries also. Eggs were inserted in the bean of young immature green berries. The significance of this oviposition behaviour is discussed. Far more ovipunctures were made by ovipositing females than were used for egg deposition. Each ovipuncture contained an average of 1.69 eggs. Females lived an average of 12 days, including a pre-oviposition period of five to seven days. The number of eggs oviposited in the duration of 27-29 days of active oviposition was far below what was expected
