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.
A wasp species native to Asia was discovered in North America for the first time and shows promise as a potential biological control for kudzu bug.
A new review of 30 years' worth of research concludes that, while lone star ticks are guilty of transmitting bacteria that cause several human illnesses, Lyme disease is not one of them.
Researchers at New Mexico State University have found that bed bugs are capable of hosting the pathogen that causes Chagas disease for up to 97 days, and the pathogen can persist even through the bed bug's molting process.
A new "IPM Criteria Guidance Document" provides integrated pest management professionals, extension entomologists, and growers a common set of criteria to compare pesticides and make a selection based on compatibility within a given IPM plan.
Sightings of the brown recluse are rare outside its known range, but if its presence is confirmed, here's what to do about it.
Extension entomologists at Texas A&M have used short instructional videos to supplement face-to-face education sessions for growers on integrated pest management, and analysis of their use shows the videos are improving learning outcomes.
In a study on three commonly cited natural spider repellents, both chestnut and peppermint oil showed apparent repellent effects on two species of spider but not on a third. Meanwhile, lemon oil did not have a significant effect on any of the three species included in the study.
A new study in the Journal of Medical Entomology offers the best look yet at the Haller's organ, a small sensory pit on the forelegs of ticks that they use to detect heat and chemical odors emitted by potential hosts.
