Abstract

ABSTRACT: The Sterile Insect Technique (SIT) is a method of pest control used in the management of Ceratitis capitata (Medfly). This technique is based on the mating and transfer of ejaculate sperm to the wild female population from released sterile males. This transfer will induce sterility in the female through sperm dominant lethal mutations. Consequently, the factors influencing sperm transfer and sperm storage are issues that must be understood to enable successful SIT implementation. Age, size, nutritional status, copula duration, and irradiation are the most important factors that affect sperm transfer and storage. Inconsistent results from studies investigating the influence of these factors on sperm transfer/storage may be due to, the strain of fly studied and variability in the sexual experience of the flies used. In this review, we highlight the interaction between these factors, issues that still need to be addressed, and propose future directions for the improvement of medfly males' sexual performance and the successful application of SIT against this pest.
