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 […]

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, […]

Why Stink Bug Pheromone Traps Perform Poorly During Winter Invasions

brown marmorated stink bug

Score one for the brown marmorated stink bug, again. Since the pernicious pest arrived in the United States nearly 20 years ago, it has proven difficult to fend off, attacking crops in the summer and invading homes in the fall and winter. And, as a team of researchers has recently found, one of the leading […]

Adding Pheromones to Baits Helps Control Invasive Argentine Ants

By Josh Lancette Argentine ants have been marching across the United States for the past few decades, despite the best pest control efforts. However, the authors of a new study published in the Journal of Economic Entomology may have found a better, more environmentally friendly way to stop the procession. The Argentine ant, Linepithema humile, is […]

Sex Attraction Pheromone Improves Detection of a Threatened Beetle

By Dick Arnold, Ann Ray, and Jocelyn Millar Pheromones are widely used for detecting, monitoring, and controlling insect pests, but they’ve seen little use for detection of endangered species. However, volatile pheromones show tremendous promise for monitoring endangered and threatened insect species, because traps baited with pheromones can be highly selective and very sensitive, targeting […]
