Technical Abstract: Control in SIT is achieved by the massive release of sterile males which copulate with wild females. Females mated by sterile males produce no offspring and rarely copulate again. For the optimization of SIT sterile males must compete equally with wild males for females. Detailed studies have shown that gonadotropic activity cycles are closely correlated with production cycles of pheromones and juvenile hormones coordinate both physiological events. Our goal in this project was to develop and incorporate techniques juvenile hormone application in mass rearing protocols of fruit flies for release as sterile insects. We have documented that the use of juvenile hormone accelerates the development of reproductive competition and sexual signals in the Caribbean fruit fly, a pest that lives in Florida and is under quarantine restrictions in other citrus areas of the United States and also is of great importance quarantine for fruit production in our country. The incorporation of juvenile hormones in insect mass rearing to improve the effectiveness of control strategies using the sterile insect technique for fruit flies is an important step in developing a highly efficient and environmentally friendly method of controlling these invasive exotic pests. The development of techniques to speed up the male reproductive competition would increase the competitiveness of sterile males and efficiently improve the SIT under which reduce the high impact of mortality of infertile males after release and the cost associated with managing adults before release could also be reduced considerably. This chapter describes and proposes the development of a technology for the practical application of juvenile hormone in the process of releasing sterile fruit flies as well as discuss the use of juvenile hormone improves the efficiency of the SIT to increase competitiveness of sterile males.
