    Notes: Abstract Courtship song and mating speed of hybrids betweenDrosophila melanogaster andD. simulans were investigated. The courtship song of hybrid males is identical to that ofD. simulans, suggesting that X chromosome determination, known from the cross betweenD. pseudoobscura andD. persimilis, is also possible here. Wingbeat frequency of hybrids is intermediate between that of the two parents, demonstrating that courtship song and wingbeat frequency are inherited independently of each other. In mating tests, hybrid males court and are accepted byD. simulans females more than hybrid females (presumably because their song is more “acceptable” to the former).D. melanogaster females reject hybrid males. Hybrid females acceptD. melanogaster males readily, hybrids less readily, andD. simulans least.

    Notes: Abstract The effect of temperature and sex on spatial distribution ofDrosophila melanogaster adults was studied in a specially designed apparatus. It was observed that individuals tend to aggregate in sections of the sphere independently of sex and temperature. Nevertheless, decrease in temperature increase aggregation. The mobility of both males and females indicates a megative geotactic tendency.

    Notes: Abstract The phototactic responses of four recently collected isofemale strains ofDrosophila melanogaster andDrosophila simulans were measured in a light gradient from 590 to 10 lux. High light intensities were preferred by most flies, but a small proportion of flies preferred the lowest light intensity. Based on the strains tested,D. simulans showed greater phototaxis thanD. melanogaster, and within each species variability was found. The niche breadth ofD. melanogaster appears likely to be greater than that ofD. simulans for phototaxis in the light gradient. These results are in general qualitative agreement with earlier results published on dispersal activities from the same populations.
