Notes From Puerto Rico: Quakes Increase Risk for Mosquito-Borne Disease Outbreak

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.

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.

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.

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.

Japanese Encephalitis - Epidemiologic Triad

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.
