ABSTRACT
The Natal fruit fly, Ceratitis rosa, is by far the most important due to its extensive distribution in the island and wide host range. This chapter focuses on oviposition behavior and the visual stimuli of the oviposition site acting at very short distances. The use of only wild flies is important because R. J. Prokopy et al. observed differences in the choice of oviposition site between wild and laboratory C. capitata. Oviposition attempts by females were also more frequently observed in black domes than in blue, grey, or white ones. On the black background the only significant difference was observed in the number of oviposition attempts. The positive correlation between oviposition parameters and color hue suggests that the color choice is probably linked with spectral preferences.
