【 摘 要 】

The influence of four host fruits, orange (Citrus sinensis L.), papaya (Carica papaya L.), mango (Mangifera indica L.) and apple (Malus domestica Borkh) on oviposition behavior of Ceratitis capitata (Wiedemann, 1824) was evaluated. Experiments were carried out on two C. capitata laboratory-reared populations: one with artificial diet for 10 years with periodic introduction of wild flies and other reared with artificial diet for 20 years without wild flies introduction. In acceptance experiments two pieces of a single fruit type were exposed to a group of 10 females; after 48 hours, these were changed by two new pieces of the same fruit type, and, in the end of the fourth day, the experiments were concluded. In preference experiments, two pieces of different fruits were offered to the females. These experiments were driven under the same conditions of the acceptance ones. Acceptance and preference experiments for both populations showed the following choice hierarchy: papaya > mango > orange > apple. The acceptance experiments showed no differences in the number of eggs/female/day laid in the first 48 hours and in the last 48 hours of the experiments. The amount of eggs in the two pieces of fruits offered to the females was similar. In spite of the two populations present similar behavior in relation to host hierarchy, the number of laid eggs was different, being larger for the population reared without wild flies introduction.
