Eastern Larch Beetle Outbreak Just Keeps Going When Winter’s Not So Cold

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.

Mites Emerge as Key Vector in Encephalitis Outbreaks in India

Larval mites, known as "chiggers," from the family Trombiculidae are vectors of the bacteria that causes scrub typhus. The infection has been implicated as a common cause of acute encephalitis syndrome in India, where public health professionals are looking to better understand the variety of mite species present on rodents and their rates of infection.

Bactrocera dorsalis

Gut Microbes Can Help Insects Beat Pesticides

Insects have evolved a variety of mechanisms to try to overcome the effects of insecticides—including, in some cases, help from the bacteria and other microbes living in insects' guts. A growing number of studies indicate a link between symbiotic microbes and insecticide resistance in a diverse range of insects.

lone star tick - Amblyomma americanum

Landscape Terrain Provides New Angle for Measuring Tick Abundance

A study of lone star ticks in the forested Missouri Ozarks found that nymphs and adults were more abundant in valleys and on north-facing hills than in other areas. Meanwhile, nymphs appeared less often in the areas of greater temperature variability, while adults were less prevalent with increased elevation.

Study Shines a (Fluorescent) Light on Invasive Fruit Fly Trapping

To estimate the catch rate of traps for invasive spotted-wing drosophila fruit flies in tart cherry orchards, researchers at Michigan State University first marked thousands of flies with fluorescent dust and released them. Then they counted the recaptured flies under ultraviolet light.

Pepper with European corn borer larva

Bt Corn Adoption Benefits Other Crops, Too

A new study of 40 years' worth of data from the mid-Atlantic region of the United States finds that widespread adoption of insect-resistant Bt corn has reduced pest damage and the need for insecticide applications in offsite, non-Bt crops such as pepper, green beans, and sweet corn, as well.

Got Aphids? Call in the Reinforcements With Banker Plants

To manage pest infestations in greenhouses, banker plants draw in different insect species that don’t feed on the main crop but do serve as hosts for predator insects that will also attack the pest on the main crop—a useful (and green) tool for integrated pest management.

This is What 2,000 Termites Eating a Model House Looks Like

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.

spotted lanternfly - Lycorma delicatula

Spotted Lanternfly: States Urge Citizens to Report Sightings of Invasive Insect Hitchhiker

First encountered in the United States in Pennsylvania in 2014, the spotted lanternfly had spread to New York, Delaware, and Virginia by early 2018. The invasive insect threatens Tree of Heaven as well as grapes, hops, and fruit trees, and it has a penchant for hitchhiking. Anyone sighting spotted lanternfly is urged to report it to their state agriculture department or local extension office.
