Variation in morphological and behavioral traits among isofemale strains ofDrosophila prolongata(Diptera: Drosophilidae)

摘要: Drosophila prolongata, a member of the rhopaloa subgroup melanogaster species group, occurs in Southeast Asia. prolongata is known to have unique and prominent sexual dimorphism, with extraordinarily thick elongated forelegs only males. Mating behavior D. prolongata also characteristic: males perform “leg vibration” their courtship toward females, which play an important role. Comparisons closely related suggest that these morphological behavioral traits evolved rapidly after divergence D. prolongata. In present study, variation was examined among strains derived from single females collected natural habitats. Significant variations were detected size various body parts, aggressiveness interactions between males, mating behavior. However, no obvious relationship observed traits. These results suggested genetic factors contribute The characterized this study are useful for studies on mechanisms underlying evolution characteristic
