Brett Smith for redOrbit.com - Your Universe Online Two studies published in the Journal of Medical Entomology this month have revealed new insights into the behavior of bed bugs and possibly shown new ways to deal with these tenacious pests. One four-year study, from epidemiologists at the University of Pennsylvania’s School of Medicine, found that bed bug infestations around the city of Philadelphia tended to be at their highest in August and lowest in February. "There is...

Researchers monitored WNV in mosquitoes in the field and in the lab, and observed how the virus is transmitted between generations In California Culex mosquitoes are considered to be the principle vectors of West Nile virus (WNV), which infects birds, humans, and other mammals during the summer. In addition, these mosquitoes may also serve as overwintering reservoir hosts as the virus is passed "vertically" from female mosquito to egg, then larva, and then adult. To find out how often...

[ Watch the Video ] Scientists have created a new type of housefly control device that has proven most effective in killing an insect that carries as many as 100 types of germs, researchers from the University of Florida (UFL) announced Wednesday. Flies have been known to spread diseases such as dysentery, typhoid fever and cholera, and they are often the first pests to occur in abundance when infrastructure is disrupted due to war or natural disasters, such as hurricanes or tsunamis....

Lyme disease is the most commonly reported vector-borne disease in the United States, with the majority of cases occurring in the Northeast. It has been three decades since the agent of the disease, the spirochete Borrelia burgdorferi, and the ticks that vector it were identified. However, the number of Lyme disease cases have steadily increased. In a new article appearing in the forthcoming issuue of the Journal of Medical Entomology called "What Do We Need to Know About Disease Ecology...

A vaccine that protects cattle against East Coast fever, a destructive disease in eastern and central Africa, is being developed by scientists at the U.S. Department of Agriculture (USDA) and the International Livestock Research Institute (ILRI) in Kenya. Entomologist Glen Scoles, veterinary medical officer Massaro Ueti and research leader Don Knowles at the Agricultural Research Service (ARS) Animal Disease Research Unit (ADRU) in Pullman, Wash., have been working on the collaborative...

Head lice shrivel in study as device hits the market Four years after the LouseBuster prototype made headlines when research showed the chemical-free, warm-air device wiped out head lice on children, a new study reveals that a revamped, government-cleared model is highly effective. "For a louse, it's like sticking your head out a window at 100 miles an hour; they're going to get dried out," says University of Utah biology Professor Dale Clayton, senior author of the study and a founder of...

Emory University researchers believe they have come up with the cheapest, most efficient way yet to monitor adult mosquitoes and the deadly diseases they carry, from malaria to West Nile Virus. Emory has filed a provisional patent on the Prokopack mosquito aspirator, but the inventors have provided simple instructions for how to make it in the Journal of Medical Entomology. "This device has broad potential, not only for getting more accurate counts of mosquito populations, but for better...

A compound of the Tauroniro tree in South America has been found to be effective in deterring mosquitoes from biting and to repel ticks, researchers said. The study, published in the Journal of Medical Entomology found that isolongifolenone deters the biting of the mosquitoes -- known spreaders of diseases such as malaria, West Nile virus and Lyme disease -- more effectively than the widely used synthetic chemical repellent N,N-diethyl-3-methyl benzamide, known as DEET. It also repelled...

Isolongifolenone found as effective as DEET against mosquitoes and ticksIsolongifolenone, a natural compound found in the Tauroniro tree (Humiria balsamifera) of South America, has been found to effectively deter biting of mosquitoes and to repel ticks, both of which are known spreaders of diseases such as malaria, West Nile virus, and Lyme disease.  Derivatives of isolongifolenone have been widely and safely used as fragrances in cosmetics, perfumes, deodorants, and paper products, and...

U.S. entomologists say they've determined smaller mosquitoes are more likely to be infected with viruses causing human diseases than are larger mosquitoes. The researchers said they fed mosquitoes blood contaminated with the dengue virus and later tested them for infection at the Florida Medical Entomology Laboratory, taking into account the size of each mosquito by measuring the length of their wings. They discovered smaller-sized mosquitoes had higher infection rates and greater...
