New, Fast DNA Method Spots Pesticide-Resistant Ticks

In its effort to keep cattle fever ticks from escaping quarantine in five counties along the southern Texas border, researchers at the U.S. Department of Agriculture have developed an overnight DNA test that can detect ticks' genetic indicators of resistance to permethrin, a common pesticide used to manage ticks.

Study Details Mechanics of Flea Beetles’ Big Jumps

The tribe of leaf beetles known for their incredible jumping strength use a powerful catapult-like mechanism to spring away from looming predators. A team of Chinese and U.S. scientists illustrate the biomechanics of these beetles' jumps in a new study and say the findings could hold lessons for bio-inspired robotics.

Spotted Lanternfly: Large Potential Range in U.S. and Beyond

A new study published today in the Journal of Economic Entomology models potential suitable habitat for the invasive spotted lanternfly and shows large swaths of the United States and beyond are likely to be vulnerable should the spotted lanternfly continue to spread.

Assay Array: Entomologists’ Lab Tests Expose Insect Secrets

Entomologists can find out a lot about an insect through some simple chemical reactions in a lab. A new review offers a guide to the wide variety of tests, or assays, that can be conducted to measure the fats, sugars, and other compounds in an insect's body—thereby revealing useful clues about how it stores and uses energy.

Organic Dust Takes a Bite Out of Ticks

Researchers at the USDA-Agricultural Research Service find promising results using clay and silicate dusts to combat lone star ticks. They hope the dusts could be a useful tool against tick species that transmit deadly pathogens to livestock.

New and Easy Marking Method Tracks Bees Without Killing Them

A new study published in the Journal of Insect Science outlines a new technique that quickly, simply, and inexpensively marks bees to track their movement—and it's non-lethal, too. It could make for an valuable improvement for mark-and-recapture methods for these pollinators.
