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.
Honey bees are in high demand for pollinating crops, and hives are often trucked thousands of miles a year to serve different crops in different regions and seasons. But researchers say honey bees show signs of stress from all that travel.
New Zealand is working hard to keep the invasive brown marmorated stink bug from reaching its shores, and researchers there are working with colleagues at the U.S. Department of Agriculture to understand the dynamics of the pest's ocean voyage aboard cargo ships bound for the island nation, in hopes of finding new ways to detect and prevent its arrival.
Some researchers willing to question conventional wisdom, some crafty experimentation, and some high-tech microscopic imagery all add up to a discovery about the Varroa destructor mite that upends years of understanding about how it parasitizes honey bees.
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.
A new study shows that long-lasting insecticide netting could have promising applications in stored-product facilities to protect foods like wheat, corn, and soybeans from insect pests.
Assessing the potential risk of minor, sporadic early-season pests is challenging. A new collection of profiles in the Journal of Integrated Pest Management aims to help growers and IPM professionals make more-informed decisions about whether methods such as preventative insecticide seed treatments are warranted.
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.
The return of the screwworm to Florida in 2016 was a surprise, but entomologists with the USDA and local, state, and international partners were prepared to respond. A new, in-depth report in the Journal of Medical Entomology shares a detailed account of their work re-eradicating the pest via the sterile insect technique—plus new lessons learned along the way.
