Abstract | Mosquitoes are the culprits of some of the most important vector borne diseases. A species’ potential as a vector
is directly dependent on their pattern of behaviour, which is known to change according to the female’s physiological
status such as whether the female is virgin/mated and unfed/blood-fed. However, the molecular mechanism triggered
by and/or responsible for such modulations in behaviour is poorly understood. Clock genes are known to be responsible
for the control of circadian behaviour in several species. Here we investigate the impact mating and blood-feeding
have upon the expression of these genes in the mosquito Aedes aegypti. We show that blood intake, but not insemination,
is responsible for the down-regulation of clock genes. Using RNA interference, we observe a slight reduction in
the evening activity peak in the fourth day after dstim injection. These data suggest that, as in Drosophila, clock gene
expression, circadian behaviour and environmental light regimens are interconnected in Ae. aegypti. | pt_BR |
