A bed bug infestation hadn’t been seen in Costa Rica since the late 1990s—until now. Researchers at the University of Costa Rica have confirmed that specimens collected from a home near San Jose in 2017 are indeed bed bugs and, surprisingly, of the temperate-zone species Cimex lectularius and not the tropical bed bug, Cimex hemipterus.
In the wetlands of the southern plains of the United States, the damselfly Enallagma civile thrives, but a new study shows rising temperatures could affect the growth, development, and survival of the species in the region.
A recent Journal of Medical Entomology study investigates the ability of essential oils to repel mosquitoes.
New research shows traps with eugenol and phenethyl propionate—and leaving out geraniol—remain effective in catching Japanese beetles but significantly reduce bycatch of native bees. Plus, entirely green, brown, black, or red traps are least attractive to native bees.
In two endangered beetle species that live in the Edwards Aquifer in Texas, males and females are nearly indiscernible. A new study suggests the quickest way to ID males versus females is to shine a light through them, illuminating internal organs that reveal the difference.
