More than 175 international insect-science leaders and others involved with agriculture and public health met recently in Orlando, Florida to take part in the “International Entomology Leadership Summit: Improving the Human Condition through Insect Science.” The goal was to engage and empower worldwide entities to take on Grand Challenges we face in the coming decades […]

Education, Mosquito Management Programs, and Cooperation Needed to Stop Zika, Dengue, and Chikungunya

This 2006 photograph depicted a female Aedes aegypti mosquito while she was in the process of acquiring a blood meal from her human host, who in this instance, was actually the biomedical photographer, James Gathany, here at the Centers for Disease Control.  The feeding apparatus consisting of a sharp, orange-colored “fascicle”, which while not feeding, is covered in a soft, pliant sheath called the "labellum”, which retracts as the sharp stylets contained within pierce the host's skin surface, as the insect obtains its blood meal. The orange color of the fascicle is due to the red color of the blood as it migrates up the thin, sharp translucent tube. Note the distended abdominal exoskeleton, which being translucent, allowed the color of the ingested blood meal to be visible.

DF and DHF are primarily diseases of tropical and sub-tropical areas, and the four different dengue serotypes (DEN-1, DEN-2, DEN-3, and DEN-4), are maintained in a cycle that involves humans and the Aedes mosquito. However, Aedes aegypti, a domestic, day-biting mosquito that prefers to feed on humans, is the most common Aedes species. Infections produce a spectrum of clinical illness ranging from a nonspecific viral syndrome to severe and fatal hemorrhagic disease. Important risk factors for DHF include the strain of the infecting virus, as well as the age, and especially the prior dengue infection history of the patient.

The Entomological Society of America (ESA) and Sociedade Entomológica do Brasil (SEB) held a Summit in Maceió, Alagoas, Brazil on 13 March, 2016 to discuss the Aedes aegypti mosquito, which is the primary transmitter of Zika, dengue, chikungunya, and yellow fever. While the Summit featured talks on many aspects of mosquito biology, behavior, and control, […]
