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 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.
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.
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.
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 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 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.
A new study in Connecticut finds that residential habitats harbor a greater diversity of animal hosts for blacklegged ticks, many of which don't transmit the Lyme disease pathogen Borrelia burgdorferi to ticks as well as white-footed mice do, thereby leading to lower levels of the pathogen's presence in residential areas compared to woodland habitats.
A new study shows that fertilizer present in water where mosquitoes breed can boost growth of bacteria, algae, and fungi, which mosquito larvae feed on, resulting in accelerated larval development and greater survival rates to adulthood.
A naturally occurring botanical compound found in anise, fennel, vanilla, and cranberries might be effective in deterring the larval stage of the lone star tick
Light traps are useful collecting devices to sample large numbers and species of insects, but they also may mask infestations of some insect-borne illnesses and even expose humans to disease vectors.
Millions of years of evolution have made ticks highly specialized bloodsuckers. In fact, researchers who have studied tick saliva have found a range of compounds that fight back host defenses […]
Indigenous cultures in Colombia have known for a long time that stings from the little fire ant, Wasmannia auropunctata, can cause corneal lesions. Medical doctors are just figuring it out.
Three-quarters of counties in the contiguous United States present suitable environmental conditions for at least part of the year for either Aedes aegypti or Aedes albopictus mosquitoes to survive if introduced, according to researchers […]
