Detecting pest insects across large areas means placing vast numbers of traps, with associated costs to set them up and check them regularly. Grid patterns have been the traditional choice, but a new study shows trap-placement patterns using parallel lines could be just as effective with much lower servicing requirements.
Detecting the presence of the invasive spotted-wing drosophila could soon get easier with a new molecular test for analyzing DNA in bulk trapping samples—sensitive enough to sniff out just one target fruit fly in a sample of 2,000. And the best liquid for preserving trapped flies' DNA comes from the dental-care shelf.
New to insect collecting? Whether you're a student just getting started in entomology or a hobbyist exploring your own backyard, here's a primer on tools and tactics for gathering a variety of insects and arthropods.
The Japanese beetle (Popillia japonica) is a widely known invasive species in North America. Adults feed on more than 300 plant species and can be downright difficult to manage. A new guide in the open-access Journal of Integrated Pest Management reviews their invasion history, ecology, and management.
In many agricultural settings, insect pest traps can also attract bees. In a new report, a group of researchers examine ways to reduce bee bycatch in pest traps while also exploring how bee bycatch can aid in assessing bee biodiversity, population levels, range shifts, and more.
