A new study of genetic samples from Aedes aegypti mosquitoes from around the world finds no evidence of naturally occurring infection with Wolbachia bacteria, a positive sign for efforts that artificially introduce Wolbachia to mosquito populations to reduce their numbers or interrupt their ability to transmit disease-causing pathogens.
The Aedes aegypti mosquito typically prefers humid climates, but it has gained a foothold in the arid southwestern U.S. by using manmade containers for breeding sites—in particular, flower pots and the saucers underneath them.
A new study shows that fertilizer present in water where mosquitoes breed can boost growth of bacteria, algae, and fungi, which mosquito larvae feed on, resulting in accelerated larval development and greater survival rates to adulthood.
The disruption of mosquitoes' cuticle, wing, and eye development is “proof of concept" for a new advance in the genetic engineering method known as CRISPR/Cas9.
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 […]
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 […]
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, […]
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 […]
In a recent test of Asian tiger mosquitoes (Aedes albopictus) collected in Brazil, researchers found fragments of Zika virus RNA, raising concerns that it may be carried by species other […]
Mosquito Repellents: DEET and PMD Sprays Most Effective, While Wearable Devices Disappoint, Study Finds
A search for “mosquito repellent” on Amazon.com delivers more than 28,000 product results. For a regular consumer, it can be difficult to find the ones that truly work among a […]
New Federal Report on Aedes Mosquitoes Could Signal Shift in How Zika Virus and Other Pathogens are Researched
By Johanna Elsensohn Throughout the world, a single mosquito bite can have one of many consequences: mild infection, severe illness, birth defects, death, or, for the majority of people, just […]
By Josh Lancette While recent news cycles in the United States largely have been dominated by election coverage, the threat of Zika remains a concern both locally and globally, with […]
Scientists reduced the cases of dengue by 91% in the city Piracicaba, located in the Brazilian state of São Paulo by using sterile insects
Researchers at the University of Wisconsin–Madison have confirmed that a benign bacterium called Wolbachia pipientis can completely block transmission of Zika virus in Aedes aegypti, the mosquito species responsible for […]
By Harvey Black As mosquito-borne diseases that were once rare or unseen in the United States are making their presence known in the country, a team of researchers from the […]
(This blog post contains excerpts from an article by Kathy Keatley Garvey.) On May 26, 2016 a symposium on Zika was held at the University of California, Davis. Speakers included […]
By Ed Ricciuti With Zika, dengue, and chikungunya spreading, and yellow fever re-emerging, health workers are ramping up surveillance of the ubiquitous Aedes aegypti mosquito that carries these arboviral diseases. […]
