摘要
Morphologic analysis of geographic strains of Musca domestica carried out on natural and laboratory experiments starting with 400 and 800 eggs showed phenotypic variations related with latitude. Females of the natural populations showed clines for several morphological traits of the wing, whereas male flies showed a reduction in the dispersion measures (s2 and CV) of wing width and length. The same reduction was obtained for males, females and total number of flies of the natural populations in dispersion of the number of bristles on the fourth abdominal sternite. A significant negative correlation was observed for the head width of females and for the total number of flies emerged in the laboratory experiments started with 400 eggs. All flies produced by the experiments starting with 800 eggs showed a reduction in variability of dispersion of the bristles on the fourth abdominal sternite in the strains obtained from locations south of the area analyzed. Evolutionary aspects of these correlation coefficients between morphometric traits and latitude are discussed.
