By Meredith Swett Walker A spate of tree deaths in California has arborists, park managers, and home owners alarmed. Keen-eyed tree caretakers might notice a cluster of tiny holes in the bark of affected trees—almost as if the tree had been shot with a Lilliputian shotgun. But the culprit is not a tiny tree hitman […]

Odorant Receptor Gene in Codling Moth Also Affects Egg Production

A funny thing happened on the way to testing the CpomOR1 odorant receptor. Researchers at the USDA-Agricultural Research Service conducted an experiment on codling moth (Cydia pomonella) using the CRISPR/Cas9 gene-editing method to study the role played by a specific gene known as CpomOR1. The gene is highly expressed, or “switched on,” in the antennae […]

The Potential U.S. Economic Cost of a New Sweetgum-Killing Pest

It’s never too early to work toward preventing the arrival of a potentially destructive invasive species. That’s why researchers at the University of Florida have developed a model to estimate the possible financial cost to the American forestry sector of a newly discovered beetle in China, should it arrive on U.S. shores. The beetle, first […]

Line Trapping: A Promising Method for More Accurate Pest Monitoring

pheromone line-trapping

It’s easy to think of a pheromone trap as a lure, putting out a scent and waiting for insects to come rolling in. But insects aren’t sharks; they don’t sense the proverbial blood in the water from great distances. They move much more randomly, and pheromone plumes don’t broadcast all that far—a couple dozen meters, […]

UV Light Best for Luring Cigarette and Drugstore Beetles

By Edward Ricciuti Their common names—cigarette beetle and drugstore beetle—only hint at the amazingly eclectic and destructive diet of two related insects, which can wreak havoc on products stored in home pantries, warehouses, businesses, and even museums and libraries. New research by scientists at Hamamatsu University and Okayama University in Japan documents that LED ultraviolet […]
