Gustatory receptor expression in the labella and tarsi of Aedes aegypti.

چکیده
The yellow-fever mosquito, Aedes aegypti, infects a growing number of people every year with dengue, yellow fever and chikungunya viruses. Contact chemoreception in mosquitoes influences a number of behaviors including host-selection, oviposition and feeding. While these behaviors are in many instances well documented, the molecular mechanisms mediating them are not well understood. Here we report the results of sequencing total messenger RNA in the labella and tarsi of both male and female Ae. aegypti to reveal Gustatory Receptor (GR) gene expression profiles in these major gustatory appendages. Gene expression levels in each tissue were verified by RT-qPCR. We discuss potential functions for the GRs revealed here by considering homologous GRs in other insects. Specific GRs provide molecular targets for modification of gustatory-mediated behaviors in this important disease vector.

The genetics of chemoreception in the labella and tarsi of Aedes aegypti.
The yellow-fever mosquito Aedes aegypti is a major vector of human diseases, such as dengue, yellow fever, chikungunya and West Nile viruses. Chemoreceptor organs on the labella and tarsi are involved in human host evaluation and thus serve as potential foci for the disruption of blood feeding behavior. In addition to host detection, these contact chemoreceptors mediate feeding, oviposition and...

Dengue is a vector-borne disease caused by dengue virus. According to the recent report of CDC that one-third population of the world are at high risk with Dengue fever. The prevalence of the dengue hemorrhagic fever was found more in tropical and sub-tropical regions of the world. Aedes mosquitoes was reported as the main cause of transmission of dengue virus. So the current study was planned ...

Background: Aedes aegypti is the main vector of the yellow fever and dengue virus. This mosquito has become the major indirect cause of morbidity and mortality of the human worldwide. Dengue virus activity has been reported recently in the western areas of Saudi Arabia. There is no vaccine for dengue virus until now, and the control of the disease depends on the control of the vector. Objectiv...
