Some Infected Mosquitoes Found to Be Less Responsive to Repellents
A new meta-analysis points to opportunities for future research to improve the effectiveness of mosquito repellents.
“Natural” Oil Mosquito Repellents May Fend Off Mosquitoes—Briefly
A recent Journal of Medical Entomology study investigates the ability of essential oils to repel mosquitoes.
Electropenetrography Helps Researcher Break Down Mosquito Bites
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.
Study Finds Bigger Mosquitoes in Baltimore Neighborhoods with More Abandoned Buildings
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.
West Nile Virus: Reflections on 20 Years in Pursuit of an Elusive Foe
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.
Wolbachia-Infected Mosquito Release Shows Encouraging Results
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.
Trap Modifications Collect Mosquito Waste for Virus Detection
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.
Meet the Mosquito With a Big Appetite—for Other Mosquitoes
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.
Satyrization is No Laughing Matter for Aedes Aegypti Mosquitoes, But Pickiness Has a Price
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.
The Hole Story: How Mosquitoes Seek Out Gaps in Nets or Screens
A new study suggests mosquitoes actually aren't all that good at finding holes in netting, doing so mostly by chance.
Need to Mail Mosquitoes? Pack Them Up Nice and Snug
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 Case for Greater Focus on Mosquitoes and Other Arthropod Vectors in Epidemiology
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.
Funny Honey at the Zoo Reveals Bees’ Foraging on Sugar Baits
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.
Water Mites Discovered Parasitizing Two Mosquito Species in Pennsylvania
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.
Cannibalism in Mosquito Larvae Confounds Egg Counts
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.
Mosquito Sculpture Delivers Entomology, STEAM Education at Maryland Middle School
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.
