The reproductive behaviors and mating systems of the fruit-infesting species of the Dacinae tribes Ceratitidini and Dacini are increasingly well understood, while in the non-frugivorous tribe Gastrozonini, data are lacking. In the present study, the reproductive behavior of Anoplomus rufipes from North Thailand was studied in the field, other behaviors also in the laboratory. A. rufipes mated on young bamboo plants growing in areas destroyed by fire. Exudates of extrafloral nectaries produced by the young bamboo plants provided food for the females. Factors affecting the choice of the mating site were favorable microclimatic conditions and food. Courtship behavior was performed on the upper sides of bamboo leaves and included pheromone calling (abdominal elevation, anal pouch eversion, abdominal pleural distention), anal dabbing, looping flights and a specific lofting/body swaying behavior. The males searched individually for females or formed leks containing up to four males. The reproductive behaviors and lek formation of A. rufipes are compared to other Dacinae (Ceratitis, Bactrocera), and their functions are discussed. Hitherto unknown data on the general biology of A. rufipes are also included. A. rufipes larvae infested living bamboo shoots of Cephalostachyum pergracile, and the observed behaviors of the adults included locomotion, grooming, feeding, oral droplet deposition, bubbling and agonistic behavior.
