Influence of methoprene on pheromone emission and sexual maturation of Anastrepha obliqua (Diptera: Tephritidae) males
Journal of Economic Entomology 109 (2), 637-643
Abstract: It has been demonstrated that the application of juvenile hormone analog, methoprene, reduces the time required for sexual maturation and enhances mating success in several species of tephritid fruit flies. This study examined the effect of different concentrations of methoprene incorporated into the diet of adult flies and distinct sugar:protein (S:P) ratios on sexual maturity and pheromone emission of Anastrepha obliqua males. Diets with 0.2 and 0.5% of methoprene accelerated sexual maturation of males compared with untreated males. In subsequent assays, the enhancement of male pheromone emission and sexual maturation by the incorporation of 0.02% methoprene into a 24:1 (S: P) diet was confirmed. Among the volatiles released by males, (Z)-3-nonenol and (Z,Z)-3,6-nonadienol were emitted at higher quantities by flies treated with methoprene than untreated ones. The results show that methoprene accelerates sexual maturation of mass-reared A. obliqua males and increases their mating propensity. This would reduce the time required to attain sexual maturation by sterile males, thus decreasing fly handling costs and improving the efficacy of the sterile insect technique.
