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.
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.
Evaluation of the collapsible passive trap for mosquitoes shows performs as well as other commonly used traps but in a lighter, easier-to-carry design, making it an attractive option for mosquito monitoring in remote areas.
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.
Light traps are useful collecting devices to sample large numbers and species of insects, but they also may mask infestations of some insect-borne illnesses and even expose humans to disease vectors.
