Another Step Forward in Genetic Engineering of Mosquitoes

mosquitoes cuticle-color genes disrupted

“Yellow, three-eyed, wingless mosquitoes” have made headlines this week, but the researchers at the University of California, Riverside, behind the news call the disruption of mosquitoes’ cuticle, wing, and eye development a “proof of concept” for a new advance in the genetic engineering method known as CRISPR/Cas9. The method may accelerate scientists’ work toward identifying the genes to target for disruption of mosquitoes’ ability to carry and transmit human diseases.

Three-Quarters of U.S. Has Suitable Climate for Aedes aegypti and Aedes albopictus Mosquitoes

Aedes aegypti estimated range - CDC

Three-quarters of counties in the contiguous United States present suitable environmental conditions for at least part of the year for either Aedes aegypti or Aedes albopictus mosquitoes to survive if introduced, according to researchers at the U.S. Centers for Disease Control and Prevention. The two mosquito species can transmit viruses that cause Zika, dengue, chikungunya, and yellow fever. The […]

Faster ID of Mosquito Species Possible via CDC Improvements to DNA Testing Methods

Aedes aegypti or Aedes albopictus?

A crucial step in management of mosquito-borne diseases is knowing exactly what kind of mosquitoes are present in any given locale. Are they garden-variety species that aren’t carriers of human pathogens, or are they potentially dangerous vectors such as Aedes aegypti or Aedes albopictus? Identifying and discerning between those two species is important as well, […]

Entomologists Discuss Discovery’s “Mosquito” Documentary: A Live-Tweet Recap

The old adage “bad press is better than no press” has a long history, and it surely applies to coverage of insects broadly and insects that are harmful to humans, more specifically. If you missed the Discovery channel program Mosquito that aired last Thursday night, July 6, then you missed a chance to see some of […]

CDC Releases New Data Showing Gaps Remain in Surveillance for Mosquitoes That Transmit Zika

Number of years with at least one Aedes aegypti reported between 1995 and 2016

As concerns over Zika virus have grown since 2015, the U.S. Centers for Disease Control and Prevention (CDC) has turned to local public health professionals to compile data on distribution of the two primary mosquito species capable of transmitting the virus, Aedes aegypti (the primary vector for Zika) and Aedes albopictus. Their findings highlight both […]
