English abstract The objective of this work was to characterize the sexual behavior of the citrus leafminer, Phyllocnistis citrella Stainton, as the foundation for the isolation, identification, and synthesis of the complete sex pheromone of this species. Mating occurred in a time window of 2h, starting 1h before the onset of photophase. The large majority of tested insects mated in the first two days after emergence, with no significant difference between mating at day 1 and day 2. A stereotypical courtship and copulation behavior were described for this species. When mating was successful, the copulation was recorded in average for 49.6 min. In Y-olfactometer tests conducted at the time of mating activity, males were strongly attracted to caged virgin females as well as to extracts from putative pheromone glands
Portuguese abstract O objetivo desta pesquisa foi caracterizar o comportamento sexual do minador-dos-citros, Phyllocnistis citrella Stainton, como suporte para o isolamento, identificação e síntese do seu feromônio sexual. O acasalamento de P. citrella ocorre no intervalo entre 1h antes do início da fotofase e 1h após o término da escotofase, entre adultos de um e dois dias de idade. O comportamento de corte e cópula foi descrito para essa espécie, sendo a duração média da cópula de 49,6 min. Estudos conduzidos em olfatômetro tipo Y demonstraram que os machos foram fortemente atraídos pelas fêmeas virgens bem como pelo extrato natural de glândulas de feromônio sexual das fêmeas
