Grayson Brown, Ph.D., executive director of the Puerto Rico Vector Control Unit and a past president of the Entomological Society of America, reports that conditions in Puerto Rico are ripe for a potential dengue outbreak, as recent earthquakes have driven residents out of their homes, increasing their exposure to mosquitoes. The PRVCU is working with ESA and other organizations to quickly procure approximately 5,000 bed nets to help protect residents from mosquitoes.
A new meta-analysis points to opportunities for future research to improve the effectiveness of mosquito repellents.
A recent Journal of Medical Entomology study investigates the ability of essential oils to repel mosquitoes.
A recent study used electropenetrography to quantify mosquito feeding behavior. The study’s lead author sees great potential for other insect scientists to apply this method in their own work.
A recent study found that female Aedes albopictus mosquitoes are larger in neighborhoods with more abandoned buildings—and larger mosquitoes are more likely to survive and breed.
The body of knowledge built since the arrival of West Nile virus in the Americas in 1999 is now powering efforts to minimize its impact and prepare for the invasion of other mosquito-borne diseases. A new special collection in the Journal of Medical Entomology takes stock of lessons learned and progress made over the past 20 years of West Nile virus research, surveillance, and control.
A pilot program in a 150-acre zone in Miami in 2018 released as many as 375,000 Wolbachia-infected male Aedes aegypti mosquitoes per week for six months and succeeded in reducing the female Ae. aegypti population by more than 75 percent.
Public health officials could soon be able to detect viruses in mosquitoes in the wild much more quickly and easily—thanks to the insect equivalent of a urine test. A new study in Australia shows that two kinds of commonly used mosquito traps can be readily modified to collect mosquito excreta, or liquid waste droplets, to be tested for signs of viruses.
The mosquito species Toxorhynchites rutilus is harmless to humans but is a voracious predator of other mosquitoes. Researchers in Houston, Texas, are hoping the "mosquito assassin" could be put into action as a tool for controlling mosquitoes that carry human pathogens—if they can find an efficient way to raise the predator mosquitoes in the lab.
When their ranges overlap, two invasive mosquito species mate but produce no offspring, in an event known as satyrization. They can evolve quickly to learn to avoid each other, but that choosiness may cost the mosquitoes in other ways.
A new study suggests mosquitoes actually aren't all that good at finding holes in netting, doing so mostly by chance.
Several emerging mosquito-management methods require the transport of mosquitoes to precise locations. There, lab-reared mosquitoes—for instance, sterilized males—mix with wild mosquitoes and hinder the population's ability to reproduce or transmit disease. But, getting mosquitoes from lab to wild presents logistical challenges. A team led by researchers at New Mexico State University are tackling this problem and have made a surprising discovery about just how tightly live mosquitoes can be packed up.
The textbook approach to managing disease outbreaks focuses on pathogen, host, and environment but leaves out insect or arthropod vectors. For afflictions such as Zika, malaria, and Lyme, a report in the Annals of the Entomological Society of America proposes a new version of the classic 'epidemiologic triad' that better reflects the complexities of managing vector-borne diseases.
In the course of a study on mosquito movement, researchers discovered that local colonies of honey bees had foraged on a nontoxic sugar bait meant for the mosquitoes. The bait was dyed red to track mosquitoes that fed on it, but the dye also showed up in much of the bees' honey.
A survey of mosquitoes in Pennsylvania discovered 12 mosquitoes parasitized by larval mites. Water mites can reduce the survival and reproductive success of mosquitoes, and entomologists are investigating such parasitism to evaluate its potential as a method for biological control efforts.
New research shows that late-stage Anopheles gambiae larvae will eat eggs and first-instar larvae of their own species, calling into question the common view that females of the mosquito species avoid laying eggs in water where other larvae are already present.
Meet "Wiley" the mosquito, a sculpture at Bates Middle School in Annapolis, Maryland, part of a school-wide integrated education program supported by the Entomological Foundation.
