Abstract:

This paper reports the result studies on the mitotic metaphyasc chromosome for 24 species of Drosophilidae, collected from Yunnan and Guizhou provinces of China. Of the species examined, the karyotypes of Drosophila spuricurviceps D. longisetacea, D. trapezifrons, D. neobusckii and D, sp. (like D, trilutea) are reported for the first time. Moreover, the present study has also observed some differences with respect to the morphology of both femal and male of sexchromosomes in D. pulchrella, D. mutandis and D. lacertosa. Further more, we have detected some differences of chromosome number in D. triauraria, D. parvula and D. malerko-tlian. An extensive karyotpic variations of the geographical distribution have been observed.
