Abstract
Temperature-influenced emigration behavior of Drosophila melanogster was examined over the range of 16-31.degree. C with Sakai''s migration system using 33 isogenic lines derived from a natural population. Interaction of genotype with temperature was an important factor for emigration response behavior to temperature. Three emigration response patterns (linear, optimum-temperature, and threshold-temperature response) were found among isogenic lines in a natural population and quantitative differences were also detected in each type. The maintenance of genetic variability for temperature-influenced emigration behavior would provide evolutionary flexibility to a population under changing temperature conditions.This publication has 0 references indexed in Scilit:
