AbstractIn Aedes aegypti, the ’matrone’ substance which caused mating inhibition and stimulated oviposition in females, was present in the anterior secretory region of the male accessory glands. In the divided accessory glands of male A. triseriatus, however, it was present in the posterior glands. The posterior gland substance in A. triseriatus was not species specific. It stimulated oviposition in A. aegypti and caused mating inhibition in A. atropalpus. The secretory substance of the posteriormost region in the glands of both species of mosquitoes was mucin in nature. This mucin substance effectively glued the secretory granules of the anterior region(s).

Abstract Background Mating induces behavioral and physiological changes in the arbovirus vector Aedes aegypti, including stimulation of egg development and oviposition, increased survival, and reluctance to re-mate with subsequent males. Transferred seminal fluid proteins and peptides derived from the male accessory glands induce these changes, though the mechanism by which they do this is not known. Results To determine transcriptome changes induced by seminal proteins, we injected extract from male accessory glands and seminal vesicles (MAG extract) into females and examined female lower reproductive tract (LRT) transcriptomes 24 h later, relative to non-injected controls. MAG extract induced 87 transcript-level changes, 31 of which were also seen in a previous study of the LRT 24 h after a natural mating, including 15 genes with transcript-level changes similarly observed in the spermathecae of mated females. The differentially-regulated genes are involved in diverse molecular processes, including immunity, proteolysis, neuronal function, transcription control, or contain predicted small-molecule binding and transport domains. Conclusions Our results reveal that seminal fluid proteins, specifically, can induce gene expression responses after mating and identify gene targets to further investigate for roles in post-mating responses and potential use in vector control.

Juvenile Hormone Mimic

AbstractJuvenile hormone, the secretion of the corpus allatum, apparently controls the secretory process of the male accessory glands of the yellow fever mosquito, Aedes aegypti. Topical application of a juvenile hormone mimic induces precocious and enhanced secretion. The treatment with the JH mimic not only increases the potency of males to inseminate more numbers of females, but also stimulates secretion in fully depleted glands of A. aegypti which under normal conditions do not renew the secretory process. Males whose accessory glands are depleted due to multiple matings and later treated with the mimic also inseminate. Cauterization of the corpus allatum complex has prevented the secretory function in the glands.

Normal Feeding

1. A study was made of the effect of underfeeding on the genital functions in the bull. Regular weekly collections of semen were made during (1) a 5-week pre-experimental period of normal feeding, (2) a 23-week experimental period of under-feeding, and (3) a 25-week post-experimental period of recovery.2. Although the food intake was reduced to such an extent that the bull began to lose weight at a rate of 6·5 kg. (1 stone) per week, the volume and density of semen and the motility and morphology of the spermatozoa were not significantly changed.3. In contrast to the testes, the secretory function of the male accessory glands was markedly affected by under-feeding. The concentration of fructose and citric acid in semen decreased to about 30 and 60% respectively of the original levels. During the recovery period the values for fructose and citric acid gradually returned to normal.
