Diurnal activity and sexual maturation of the South American fruit fly (Diptera: Tephritidae) in the laboratory

Atividades diárias e maturação sexual da mosca-das-frutas sul americana (Diptera: Tephritidae) em laboratório

Locomotion and grooming in immature adult Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) occurred throughout the daylight period. Feeding seemed to be slightly higher in mated than in unmated flies. Ovipositing females showed territoriality and only mated females laid eggs. Males started to display courtship behavior at 5 days old, reaching the complete sexual maturation at day 10. About 54% of the virgin mature females copulated on the day they were paired with virgin males of the same age. Female A. fraterculus seemed to require more than 30 min of mating to supply all spermathecae with sperm, and the efficiency of sperm transference after first mating was 100%.
