Maintaining Susceptibility to Insecticidal Traits in Populations of Corn Pests

In the course of insect resistance management, growers that use Bt crops face a question: whether to plant a separate nearby refuge field of non-insecticidal crops or to use a blended mixture of seeds that produce both in the same field. A new review of existing research on this question suggests the answer is highly dependent on the characteristics of individual pest species.

What Lies Beneath: Grape Root Borer an Under-Recognized Pest in Eastern Vineyards

As few as nine larvae of the grape root borer may be enough to fatally damage a grape plant with an 8-inch base circumference. They are slow killers but hard to detect. A new profile in the open-access Journal of Integrated Pest Management offers guidance on managing the pest.

In Search of Soybeans Resistant to the Brown Marmorated Stink Bug

The invasive brown marmorated stink bug “will eat almost anything.” Among its targets is soybean, the number-two crop in the United States. Researchers at the U.S. Department of Agriculture’s Agricultural Research Service are working to identify soybean breeds that exhibit resistance to the pest.

Entomologists Say Harassment and Bullying in Science are “#NeverOK”

NeverOK table at Entomology 2017

At Entomology 2017, a group of entomologists sought to facilitate a conversation among ESA members and conference participants about the issues of bullying and harassment in our workplaces and at ESA conferences. Whether we are eager to admit it or not, the scientific community is not free of such conflicts.

Today’s Termites Offer Clues to Ancient Migrations Across Southeast Asia

Macrotermes gilvus

How did a ground-dwelling insect such as the termite Macrotermes gilvus get from mainland Myanmar all the way out to the islands of the Philippines, Indonesia, and Malaysia? The answer lies in ancient land bridges that existed in eras when sea levels were lower, and researchers from Universiti Sains Malaysia say the genetic markers present in M. gilvus termites throughout varying Southeast Asia locales reveal the routes these termites—and many other terrestrial animals, as well as early humans—likely followed as they dispersed there over the past 2 million years.
