More than 20 broods of periodical cicadas inhabit the eastern United States, and researchers are refining their mapping of brood ranges with increasing precision at every new emergence. A new report in the Annals of the Entomological Society of America details new advances in mapping cicadas from researchers who studied Brood VI in 2000 and 2017.
The classic wooden hive box used by beekeepers worldwide, first designed in the 1800s, is prone to temperature swings, a new study shows. That's bad news for the honey bees inside, who must expend energy to maintain their favored internal hive temperature.
A look at the body of research on how and when day lengths trigger mosquitoes to enter winter diapause suggests more data on mosquito species' critical photoperiods and their relation to latitude and altitude could better align surveillance and management efforts with mosquitoes' seasonally active periods.
With multiple species of termites responsible for structural damage in the U.S., rapid identification is a critical part of management efforts. A team of researchers has developed a faster ID method that uses a genetic tool called inter-simple sequence repeats.
