SummaryThe eggs laid by outbred females have been collected from the time of mating until the death of the females, and the proportion of eggs hatching recorded. Initially oyer 99 % of the eggs hatch after mating to outbred males; after about 30 days the quantity of sperm in the ventral receptacle is inadequate to ensure fertilization, and few or no eggs hatch. After mating to inbred males, the initial hatch varied from 43 to 84%, and a sharp decline in the proportion hatching occurred after… 
The effect of inbreeding on male mating ability inDrosophila melanogaster
A drastic reduction in competitive mating ability and mating rate was observed at a rather low level of inbreeding, but the effect of further inbreeding was small.
Female remating inDrosophila ananassae: shorter duration of copulation during second mating as compared to first mating
The duration of copulation is shorter in second mating as compared to first mating in Drosophila ananassae, a cosmopolitan and domestic species.
Mating behavior as an indicator of quality of Drosophila subobscura males?
The genetic quality of Drosophila subobscura males was manipulated by inducing mutations with ionizing radiation and the effects of the obtained heterozygous mutations on male mating behavior were observed.
Radiation effects on Drosophila suzukii (Diptera: Drosophilidae) reproductive behaviour
The effects of male and female sterilization on mating and remating behaviour of D. suzukii are investigated and an overall low remating rate is found by Drosophila suzkii females.

Two environmental factors in Drosophila pseudoobscura that affect male courtship in D. melanogaster are examined: isolation and exposure to previously mated females.
True polyandry and pseudopolyandry: why does a monandrous fly remate?
The results illustrate the difficulties in determining the mating system of a species, even one that is well known and an excellent laboratory species, with results being highly dependent on the conditions used to assay the behaviour, and the population used.
Sex-limited inheritance of longevity inDrosophila subobscura
Significant sex differences in longevity were found in six of the nine inbred lines, in one of the twoF1 hybrid populations, and in the Galilee population, showing the importance of genes with sex-limited effects on longevity.
Competitive Mating Success and Attractiveness of Sterile and Fertile Males of Drosophila montana
The attractiveness and the mating success of fertile and sterile Drosophila montana males were studied in female-choice experiments and the successful courtships of the rt males included more licking and touching than those of the normal and br males.
Male Drosophila melanogaster have higher mating success when adapted to their thermal environment
In competition for female partners, males had significantly higher mating success at their adapted temperature compared with males adapted to a different temperature, consistent with the notion that those mutations favoured by natural selection also tend to be favoured by sexual selection.
Evolution of reproductive isolation as a by-product of divergent life-history evolution in laboratory populations of Drosophila melanogaster
It is shown that two complementary asymmetric isolating mechanisms, likely mediated by divergence in body size, underlie the evolution of incipient reproductive isolation between a set of Drosophila melanogaster populations selected for rapid development and their ancestral controls, reaffirming the belief that prezyGotic isolation can evolve much earlier than postzygotic isolation.


The effects of inbreeding on rate of development and on fertility inDrosophila Subobscura
Two brother-sister mated lines of Drosophila subobscura, theO andNF lines, were established from wild-caught females and there was no difference in either line between the rates of development of the progeny of fast and slow pairs in the first selected generation.
One of the most imiportant problems in the study of speciation has been that of the origin of reproductive isolating mechanisms, for it is by the building up of intrinsic barriers which prevent gene
A preliminary histological study of the insemination reaction in Drosophila gibberosa.
1. Macroscopic features and microscopic structure of vaginae of Drosophila gibberosa Patterson and Mainland are described in virgin females, mated females, females with testes injection, male
The genetics and cytology ofDrosophila Subobscura
SummaryThe length, of imaginal life is given for two inbred lines ofDrosophila subobscura, and for the reciprocal hybrids between them. The expectation of life at eclosion of hybrids is approximately
Genetics and cytology ofDrosophila subobscura
1. Cardinal inDrosophila subobscura, now called vermilion, is homologous with Vermilion inD. melanogaster, and poppy maroon implants are pinker in wild-type hosts.
A gynandromorph segregating for autosomal mutants inDrosophila Subobscura
SummaryA gynandromorph inDrosophila subobscura segregating for autosomal mutants is described and illustrated. It can be explained as resulting from double fertilization by X- and Y bearing sperm of
The Courtship of Drosophila Melanogaster
It is suggested that inhibition while accumulating, interacts with excitation and it is fluctuations in the resultant 'effective excitation' which determine the courtship pattern.
The causes of domestication: an attempt to integrate some ideas of konrad lorenz with evolution theory
SummaryAllopatric cultivation, usually alters the habitat, and captivity, by definition, removes the developmental systems from the range of environmental stimuli for which they have been stabilized.
