One of the best tools to detect emerald ash borer is a wasp that specializes in catching beetles. A new study compares the wasps’ mix of prey with the mix of trees in nearby forests to estimate the wasp’s foraging range—and thus determine where emerald ash borer may be present when the wasps are found with it.
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.
A new study in Connecticut finds that residential habitats harbor a greater diversity of animal hosts for blacklegged ticks, many of which don't transmit the Lyme disease pathogen Borrelia burgdorferi to ticks as well as white-footed mice do, thereby leading to lower levels of the pathogen's presence in residential areas compared to woodland habitats.
Clearing the invasive shrub Japanese barberry from a wooded area once can lead to a significant reduction in abundance of blacklegged ticks for as long as six years
By Leslie Mertz If you have ever found a deer tick crawling on your shirt or sock, you know how difficult they can be to spot. Adult females are about […]
