Resumen: "The sexual performance of Anastrepha ludens males of the Tapachula-7 genetic sexing
strain, produced via selection based on mating success, was compared with that
of males produced without selection in competition with wild males. Mating competition,
development time, survival, mass-rearing quality parameters and pheromone
production were compared. The results showed that selection based on mating
competitiveness significantly improved the sexual performance of offspring.
Development time, survival of larvae, pupae and adults, and weights of larvae
and pupae increased with each selection cycle. Differences in the relative quantity
of the pheromone compounds (Z)-3-nonenol and anastrephin were observed when
comparing the parental males with the F4 and wild males. The implications of this
colony management method on the sterile insect technique are discussed."
