title: [Variation of behavioral traits in natural Drosophila melanogaster populations from Eurasia].
abstract: Two behavior traits--phototactic response and locomotor activity--were studied in 13 populations of Drosophila melanogaster with countercurrent distribution technique. These traits were characterized by three parameters: average phototactic (locomotor) activity, normalized variance of activity and proportion of inactive flies. Males had bigger average phototactic activity and average locomotor activity, but less proportion of inactive flies than females. For phototaxis, no correlation was found between all estimated parameters and geographic localization of populations. For locomotor activity, females exhibited clinal variation in proportion of inactive flies.
