Drosophila fly article dating before 1950

We used a repeated-measures, four-factor experimental design to determine how the fecundity of Drosophila melanogaster during the first 5 days of adult life was influenced by paternal, maternal, developmental and laying temperature, with two different temperature levels (18°C vs. Laying temperature had by far the largest effect on fecundity and accounted for 79 per cent of the variance in overall fecundity: flies laying at 25°C began laying eggs about a day earlier and had much higher daily fecundities than did those laying at 18°C.

In contrast, sire temperature slightly influenced both overall fecundity and the pattern of daily egg production.

Our results demonstrate that early fecundity is extraordinarily sensitive to laying temperature (360 per cent increase if laying at 25°C vs.

at 18°C), but is relatively well buffered against developmental and cross-generational effects (maximum effect only 7 per cent, for sire temperature).Über die relative Vitalität von Drosophila melanogaster Meigen und Drosophila funebris Fabricius (Diptera, Muscidae acalypteratae) unter verschiedenen Zuchtbedingungen, in Zusammenhang mit den Verbreitungsarealen dieser Arten.

82.5% of wild-type Canton-S flies copulated within 60 minutes in circular arenas, whereas few white-eyed mutants mated successfully.

The w Mating behavior in wild-type Drosophila consists of a series of courtship rituals and subsequent copulation.

Indeed, copulation behavior in wild-type is vigorous and highly resistant to environmental stress such as a strong smell of ether.
