New Container Aids in Biocontrol of Hemlock Woolly Adelgid

Researchers deploying predator insects to attack an invasive forest pest need to monitor how well those predators' populations are growing. A new specially designed container speeds up that work by collecting and separating two different predator species at the same time.

McPhail trap

Researchers Use Simulation Model to Optimize Delimitation Trapping Surveys

When an invasive insect appears, responders must quickly set monitoring traps in the area to determine the extent of the pest outbreak. A collaboration between USDA-APHIS and USDA-ARS is working to improve such delimitation trapping survey designs and will publish new guidelines after field experiments are completed later this year.

The 2021 Brood X Cicada Emergence: A Recap

When the world's largest brood of 17-year periodical cicadas rose from the ground in spring 2021, the eastern U.S. (and beyond) was ready. Half a million crowdsourced observations later, the entomologists who followed the Brood X 2021 emergence reflect on the experience.

Zophobas morio larvae

Superworms: The Bigger, Brawnier, Hungrier Cousins of Yellow Mealworms

Larvae of the darkling beetle species Zophobas morio have earned the nickname "superworms" for their larger size and increased nutritional potential as food and feed compared to yellow mealworms. And yet less research and regulatory consideration has focused on Z. morio, something a pair of researchers in Greece hope to change.

The Promise—and Limits—of Bt Maize to Manage Fall Armyworm in Africa

As fall armyworm continues to threaten food security in Africa, the use of Bt maize offers significant potential to manage the pest. But it will be critical to manage resistance via multi-toxin crop varieties and appropriate use of refuge planting—all in forms accessible to the smallholder farmers that grow nearly all of Africa's maize.

Clues in the Clay: Decoy Insect Larvae Reveal Predator Presence in Turfgrass

Researchers at the University of Georgia are studying how clay models of caterpillars and other insect larvae can attract predator insects and arthropods in turfgrass and reveal their presence by the marks they leave behind. Their latest study fine-tunes the method by evaluating the colors, shapes, and sizes of the decoys that work best.

A Guide to Conducting Research on Commercial Farms: Advantages and Challenges

Graduate students in entomology often conduct research on commercial farms during their degree programs. This experience can be valuable for a variety of career paths, both within and beyond agricultural settings. Here's a look at some of the benefits of conducting on-farm research and tips for overcoming challenges, as well.

How Flea-Killing Fungus Could Keep Prairie Dogs From Spreading Plague

Prairie dogs in the western U.S. can carry the bacterium that causes bubonic plague, and their fleas play a primary role in spreading it among prairie dogs and to other animals. A group of scientists say insect-pathogenic fungi that target those fleas could be a useful tool in interrupting that transmission route.

A Budding Problem: Managing Corn Earworm in Commercial Hemp Production

The corn earworm is an emerging pest of commercial hemp production throughout the U.S. Boring through stalks and feeding on reproductive structures, this pest presents several management challenges for hemp producers. While integrated pest management strategies for more traditional agricultural crops are established, much work is still needed to develop effective IPM for the corn earworm in hemp.
