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.
As surveillance for ticks and the disease-causing germs they spread improves, so does Americans' access to knowledge about where the risk of tickborne disease is greatest. New data from the CDC offers up-to-date county-level maps of where blacklegged ticks are prevalent and where they've been found infected with any of seven different pathogens.
Analysis of Asian longhorned ticks collected in Pennsylvania found just one—out of more than 250 tested—carrying the bacteria that causes Lyme disease. The invasive tick is unlikely to play a role in Lyme transmission, but the research underscores the importance of active tick and pathogen surveillance and collaboration among agencies at local, state, and national levels.
The research director of a busy mosquito control district reports on the scientific discoveries made over years of examining bycatch in mosquito surveillance traps—and makes the case for bycatch as an underutilized resource with the potential to fill knowledge gaps that impede invertebrate conservation efforts.
The first-ever survey of the nation's tick-management programs reveals an inconsistent and often under-supported patchwork of programs across the country.
