We assessed the indirect response of longevity in lines selected for wing length (WL) and developmentaltime (DT). Longevity in selection lines was compared to laboratory control lines and the offspring ofrecently collected females. Wild flies (W lines), flies from lines selected for fast development (F lines), andfor fast development and large wing length (L lines) outlived control laboratory lines (C lines) and linesselected for fast development and short wing (S lines). The decline in longevity in S lines is in line with theidea that body size and longevity are correlated and may be the result of the fixation of alleles at lociaffecting pleiotropically the two traits under selection and longevity. In addition, inbreeding and artificial selection affected the correlation between wing length and longevity that occurs in natural populations of Drosophila buzzatii, suggesting that correlations between traits are not a perdurable feature in a population.
