After a 100-year flood struck south central Oklahoma in 2015, a study of the insects, arthropods, and other invertebrates in the area revealed striking declines of most invertebrates in the local ecosystem, a result that researchers say illustrates the hidden impacts of natural disasters.
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.
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.
The allium leafminer damages crops such as onions, garlic, shallots, and leeks through larval feeding and adult egg-laying in plant tissue. Native to Europe, the invasive species was first discovered in North America in December 2015 in Lancaster County, Pennsylvania.
A study in Quebec highlights the value of reporting tick bites and submitting tick specimens to public health agencies. Such "passive surveillance" outpaces field collection of ticks in identifying areas of emerging risk for Lyme disease.
When Michael Skvarla, Ph.D., joined Penn State University's entomology extension program in 2017, it wasn't long before he had a mystery on his hands: A wasp specimen from an infestation of a residence that appeared to be of a genus not previously known to invade homes in North America.
A wide variety of insects (such as mosquitoes, shown here) are raised in the laboratory. A new review of research on lab-reared insects shows that they evolve rapidly as they progress through generations raised in artificial environments.
A scanning electron micrograph shows an engorged female Ixodes angustus tick with a male I. angustus attached to its underside in typical feeding mode—a case of hyperparasitism presumed uncommon in the species.
The Aedes aegypti mosquito typically prefers humid climates, but it has gained a foothold in the arid southwestern U.S. by using manmade containers for breeding sites—in particular, flower pots and the saucers underneath them.
Researchers at the National University of Singapore have identified the gene transcription factors in butterflies that give rise to their different color patterns on the top and bottom sides of their wings.
In 2017, specimens of an "unusual-looking" tick were discovered in New Jersey and determined to be a species, Haemaphysalis longicornis, native to Asia. No established population of the species has ever been previously documented in the United States.
A newly described genus of true bug from Papua New Guinea has been dubbed "Kaytuesso," so named for a perceived resemblance to K-2SO, a droid character from the movie "Rogue One: A Star Wars Story."
American cockroaches show different individual "personalities" that relate to their fleeing behavior and preference for venturing into open spaces or remaining close to walls or other objects. A new study suggests these differences could be an evolutionary benefit for their collective fleeing response.
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.
In Pennsylvania, where emerald ash borer has been present since 2007, municipalities have found successful ash-management plans under guidance of the state's Department of Conservation and Natural Resources, and they offer a model for other regions to follow.
Evaluation of the collapsible passive trap for mosquitoes shows performs as well as other commonly used traps but in a lighter, easier-to-carry design, making it an attractive option for mosquito monitoring in remote areas.
