Abstract

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%.As atividades de locomoção e de limpeza em moscas adultas de Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) ocorreram durante todo o período fotofásico. Moscas acasaladas alimentaram-se mais do que moscas vírgens. Em oviposição, as fêmeas mostraram territorialidade e apenas as acasaladas ovipositaram. Os machos começaram a mostrar comportamento de chamamento com 5 dias de idade, alcançando a maturidade sexual completa aos 10 dias. Cerca de 54% das fêmeas vírgens e sexualmente maduras, copularam no mesmo dia em que foram colocadas juntas com machos vírgens da mesma idade. Fêmeas de A. fraterculus necessitaram de pelo menos 30 min de acasalamento para suprir as espermatecas com esperma, e a eficiência na transferência de esperma por ocasião do primeiro acasalamento foi de 100%.
