Comparison of Bisexual and Genetic Strains of Ceratitis capitata from Various Origins

Abstract

Background: The sterile insect technique (SIT) of Mediterranean fruit fly Ceratitis capitata depends on the ability of male to compete successfully against wild male in obtaining matings with wild females. Methods: To evaluate mass and wild reared the sexual performance and compatibility of medflies has been conducted in a series of field cages test. At the same time, this study has been done in the laboratory domestication as well. Three populations have been tested in this research: wild flies from of Perth Hills stone; Western Australia and Norwood road, Maida Vale, Perth; semi-wild flies after 7 to 10 generation in the lab. and a mass-reared and wild strains of flies were used in the study. Result: All the field cages have been indicating that all population of medfly are all most the same. There is no significant difference in the number of egg and sex ratio of wild population. In the mass- reared males, the performed of males are significantly poorer than wild male in achieve mating with wild female. The study has been showed that mating performances are reduced in mass-reared and semi-wild fly after 8 to 11 generation in laboratory.
