In a new study on truck-mounted mosquito-control sprays, the proportion of local mosquito populations that could potentially carry West Nile virus decreased after treatments, even though overall numbers of mosquitoes weren’t affected—an “invisible” but positive sign about the utility of such mosquito management efforts.
In an analysis of mosquito sampling across 20 years in Connecticut, mosquito populations were often correlated at sites 10 kilometers apart and sometimes as far as 40 kilometers apart. But the same data showed the presence of mosquito-borne viruses rarely correlated across distances more than 5 kilometers, complicating potential approaches to managing mosquitoes and the risk of vector-borne disease.
As climate change drives weather trends like intense hurricane seasons, even regions as far north as New England are seeing changes in mosquito populations. A Massachusetts mosquito-control entomologist shares her experience.
A new study shows the malaria-transmitting Anopheles stephensi has a strong preference for type B human blood. The finding has implications for identifying individuals at high risk of mosquito-borne disease, but those with other blood types shouldn't put away the insect repellent.
Get to know the five core tactics to manage mosquitoes using an integrated approach, based on the American Mosquito Control Association's newly updated guide, Best Practices for Integrated Mosquito Management.
