Sometimes, less is more. Case in point: the mass-rearing program that produces millions of sterile Mexican fruit flies (Anastrepha ludens) for managing wild populations. Scientists refining the effort find that a lower ratio of males to females in mating cages leads to higher fecundity and fertility in the females—and higher cost-effectiveness for the operation.
LeafByte is a free, open-source mobile app for quickly measuring leaf damage caused by herbivorous insect pests. If you've ever considered building a mobile app to aid in your research, here's a first-hand account from the Cornell entomology student who took LeafByte from idea to action.
By using the brown marmorated stink bugs' own aggregation pheromone, the pests can be lured into a condensed area, thereby reducing the area that a grower must spray with insecticide. A two-year study in apple orchards suggests the method could soon become economically feasible.
Boric acid dust is a common tool in urban pest management, but a new study shows external exposure is minimally effective against bed bugs. When bed bugs ingest boric acid, though, few survive.
New research on brown marmorated stink bug behavior indicates they prefer darker surfaces, doorways, and the north and east sides of homes—and that insecticide-treated netting offers potential as a means of nuisance control.
A new termite-control method currently in development looks to combine the advantages of a liquid insecticide application with the comprehensive impact of existing solid termite bait systems.
So, you want to know what that bug is. Here at the Entomological Society of America, we know the experts. Check out this list for a variety of resources for bug and insect identification.
The sting bug species Bagrada hilaris, sometimes known as the painted bug or bagrada bug, arrived in Chile in 2016 and has quickly become a pest of crops—but, for the first time, it has also begun to infest homes, as reported this month in the Journal of Medical Entomology.
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 […]
