Most ambrosia beetles are secondary pests on woody plants in both managed and natural landscapes. However, some of the most impactful invasive species in the world are ambrosia beetles. Megaplatypus mutatus, native to South America, has invaded other regions, and a new article in the open-access Journal of Integrated Pest Management reviews its potential impact and management strategies.
The University of Florida's Forest Entomology Lab hosts the world's largest cryo-collection of bark and ambrosia beetles. Stored at –80 degrees Celsius, the samples are critical for study of the beetles' DNA and fungal symbionts, as well as for identification of beetle outbreaks in forests.
Tiny beetles once known as tea shot hole borers are actually a group of four distinct species that appear almost exactly the same to even the trained eye. In a new study, researchers combine both physical measurements and molecular genetics to better define the members of the Euwallacea fornicatus cryptic species complex.
Advances in microscopic imaging techniques are revealing, in unprecedented detail, the structure of mycangia—the internal organs that ambrosia beetles use to store and transport the symbiotic fungi they farm.
By Meredith Swett Walker A spate of tree deaths in California has arborists, park managers, and home owners alarmed. Keen-eyed tree caretakers might notice a cluster of tiny holes in […]
