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.
Soil Ecology: Critical But Understudied in the Fight Against Ticks
In many tick species, more than three-quarters of their lives are spent off-host in the soil or among the leaf litter. A research team at Cornell University highlights an important opportunity for tick researchers and soil ecologists to collaborate to better understand what happens when the ticks aren't in contact with hosts.
Bad Roommates: Study Tracks Mice to Nests, Finds Ticks Aplenty
In the first field study of its kind, researchers confirmed Peromyscus mouse nests as understudied habitats for ticks, including blacklegged ticks and American dog ticks. Researchers are hoping to better understand the role of mouse-tick interactions within nests in the spread of tick-borne disease.
Not a Kissing Bug: Invasive Western Conifer-Seed Bug Causes Undue Alarm
As the western conifer-seed bug has arrived in South America, its resemblance to kissing bugs has caused a stir, as members of the public have readily mistaken the two. Researchers in Chile recommend accessible identification keys and educational materials to better inform both health professionals and the public.
Counting Ticks on Animals is More Complicated Than It Sounds
Simply counting the number of ticks on a host animal seems like a straightforward task, but an analysis of published tick research finds no single, standard method among scientists. A group of researchers says tick-counting methods should be as rigorous as any other scientific procedure and described clearly enough to allow their use in other studies.
Forest Service Crews Double as Tick-Surveillance Teams in Collaborative Study
A partnership between the University of Tennessee and the USDA Forest Service is a proof-of-concept for collaborative tick-surveillance programs.
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.
New Study Highlights Ups and Downs in Tick Management
A new study examines two host-targeted tick-control methods, and one shows a distinct advantage, but it's likely not cost-effective for the typical homeowner.
Edible Plant Oils Show Potential for Management of Aedes aegypti
A new study finds several edible plant oils—such as hempseed, sesame, and pumpkinseed oils—have potential utility as eco-friendly larvicides or egg-laying deterrents against the Aedes aegypti mosquito.
Mosquito Management is Key in Creating Popular Urban Wetlands
A study that shows mosquitoes might benefit from wetland-management tactics aimed at protecting frogs illustrates the complicated ecological dynamics present in urban wetlands. Understanding the habitat requirements and ecological interactions of local mosquito species is critical to balancing such wetlands' risks and benefits.
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.
Citywide Mosquito Management Effort in Puerto Rico During Zika Outbreak Offers Lessons for Future
An integrated vector management program is no small undertaking, but a program run in Caguas City, Puerto Rico, during the Zika outbreak of 2016 shows such an effort can be successful at the scale of a city of more than 140,000 people.
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.
Potential Range for Asian Longhorned Tick Covers Much of Eastern U.S.
The invasive Asian longhorned tick could find plenty of suitable habitat in North America that is similar to its native region, according to new research from the Rutgers University Center for Vector Biology.
Organic Dust Takes a Bite Out of Ticks
Researchers at the USDA-Agricultural Research Service find promising results using clay and silicate dusts to combat lone star ticks. They hope the dusts could be a useful tool against tick species that transmit deadly pathogens to livestock.
