Bison Grazing Increases Arthropod Diversity and Abundance in Tallgrass Prairie

American bison are big. They can weigh as much as 2,000 pounds and they eat a lot — so much in fact that they can change the ecosystems where they graze. Dr. Matthew D. Moran, a professor at Hendrix College, decided to find out how bison grazing affects insects and other arthropods at the Tallgrass […]

NEXRAD Radar Can Track Insect Pest Migrations

A couple of weeks ago, the U.S. National Weather Service posted satellite photos of large clouds of monarch butterflies to their Facebook page. Now scientists at the U.S. Department of Agriculture are also using radar, but this time they’re employing it to track the spread of bollworms (Helicoverpa zea), which cost cotton producers $200 million […]

Add Sunspots to the List of Possible Causes of Honey Bee Colony Collapse Disorder

In 2006 a phenomenon called Colony Collapse Disorder (CCD) emerged. Beekeepers and scientists noticed that large numbers of adult honey bees were leaving their hives and failing to return, which had large implications for farmers and growers who use honey bees as pollinators. To this day, scientists are unable to identify any single cause for […]

National Weather Service Predicts Strong Chances of Monarch Butterflies

Last week the U.S. National Weather Service posted satellite photos to their Facebook page of large clouds over the St. Louis area, which they identified as monarch butterflies. “High differential reflectivity values as well as low correlation coefficient values indicate these are most likely biological targets,” they wrote about the clouds. “High differential reflectivity indicates […]

Entomovectoring Uses Bees to Fight Fungus with Fungus

A disease called brown rot, which is caused by a fungus, costs the Australian cherry industry $150 million per year. To combat the disease, University of Adelaide researchers are trying a method called “entomovectoring,” which uses bees to deliver spores of a parasitic fungus to prevent the fungus that causes the brown rot from colonizing […]
