Abstract:

IN ORDER TO ASSEMBLE SOME EVIDENCE OF POSSIBLE PHYSIOLOGICAL DIFFERENCES WHICH MIGHT HAVE DEVELOPED AMONG LABORATORY STRAINS OF Anopheles quadrimaculatus Say, and which might lead to biological segregation, a colony from Wilson Dam, Alabama, was compared in detail with another from Bethesda, Maryland. Significant divergence was found in sexual activity, in that the former group mated at lower rates and exhibited a midwinter sexual diapause. The males of both labor-ATORY STRAINS TENDED TO MATE WITH FEMALES OF THEIR OWN ORIGIN. Biting rates on guinea pigs and chickens were also markedly different, the Wilson Dam groups again being less active. In the third year of studies, the two strains converged in these behavior patterns. No significant differences were found in other aspects of life history and morphology. Author
