PHIL Image 8934

ID#:8934
Description:Having finished the ingestion of her blood meal, this 2006 photograph depicted a female Aedes aegypti mosquito as she was in the process of flying from its human host. See PHIL# 8923 - 8933, depicted her in various feeding phases. Normally, this female would be obtaining her blood from an unsuspecting host, but in this case, the CDC's biomedical photographer, James Gathany, had volunteered his own hand in order to entice the insect to alight, and feed. Note that her abdomen had become distended due to the fact that her stomach now filled with her blood meal, and how the proboscis' labial sheath was now pulled up, pointing forward, while no longer was the fascicle inserted in the host's skin.

As the primary vector responsible for the transmission of the Flavivirus Dengue (DF), and Dengue hemorrhagic fever (DHF), the day-biting Aedes aegypti mosquito prefers to feed on its human hosts. Ae. aegypti also plays a major role as a vector for another Flavivirus, "Yellow fever". Frequently found in its tropical environs, the white banded markings on the tarsal segments of its jointed legs, though distinguishing it as Ae. aegypti, are similar to some other mosquito species. Also note the lyre-shaped, silvery-white markings on its thoracic region as well, which is also a determining morphologic identifying characteristic.
