ABSTRACT
This chapter examines the pattern of sexual behavior and involvement of signals produced during Bactrocera correcta courtship. B. correcta males possess structures similar to abdominal cilia which may produce sound in B. tryoni and B. cucurbitae. Male wing-fanning was examined to determine its importance for mating success. Matings were conducted by placing two males, one each with modified and non-modified wings, together with one female. The mating period of B. correcta is restricted to dusk. Visual signals thus appear crucial for mating acceptance by females. Females with modified sound or olfactory receptors mated as well as females with unmodified receptors. Therefore, neither acoustic nor olfactory stimuli may be important for mating acceptance by females. In nature, both sexes may be drawn to a mating site by its physical characteristics. Assembly of both sexes in the same place may be the most important first step in the mating success of this species.
