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.
Lauren Diepenbrock, Ph.D., a postdoctoral researcher at North Carolina State University and soon to be an assistant professor at the University of Florida, says she enjoys "figuring out how insects, particularly invasive species, make use of the available resources to be successful."
The current outbreak of eastern larch beetle in northern Minnesota is going into its 18th year, and researchers have found that at least some eastern larch beetles are able to reach maturity without requiring an overwintering period. In short, warmer winters mean eastern larch beetle is killing trees faster than it can be managed.
A recent study at the University of Florida found that termites baited with an insecticide known as a chitin synthesis inhibitor will still follow their natural compulsion to return to their central nest to molt, an important factor in the efficacy of such baits.
A visual analogy created by termite researcher Thomas Chouvenc, Ph.D., illustrates the damage termites can wreak upon a house. Given a small, two-dimensional wooden replica of a house (30x20 cm, 2 mm thick), a colony of 2,000 Formosan subterranean termites took only three weeks to consume it.
Travelers' luggage is an attractive harbor for bed bugs, which then hitch a ride to new locations. In the search for effective bed bug repellents, researchers at Connecticut Agricultural Experiment Station and Bedoukian Research, Inc., have found that DEET as well as several naturally derived compounds could protect luggage from attracting stowaway bed bugs.
Most Essential oils don't work to control bed bugs, although there are a few exceptions
High tunnels are a common sight in farm fields in temperate zones, where growers use them to lengthen the growing season of cold-sensitive crops. Also known as hoop houses, the […]
