West Nile Virus Infections Can Be Estimated by Observing Rainfall and Temperatures

culex-pipiens3

By Alan Bolds A study by researchers at the University of Illinois Urbana-Champaign (UIUC) found that mosquito infection rates (MIR) for West Nile virus can be estimated with statistical models based on rainfall and temperature. The study, “Predicting West Nile Virus Infection Risk From the Synergistic Effects of Rainfall and Temperature,” was published in the […]

Mowing Grass in Water-Detention Basins Increases Mosquito Populations

Culex-pipiens

Mowing grass and weeds is a useful way of managing some pests. For example, clearing yards and fields is one way of managing ticks without using insecticides because mowing discourages rodents — on which some ticks feed on. However, for other situations it may have the opposite effect. A study of the West Nile virus […]

West Nile Virus Enhanced by Wolbachia in Culex tarsalis Mosquito

Culex-tarsalis-wp

Wolbachia, a genus of bacteria that infects insects and other arthropods, has been used in the past to control mosquitoes and to hinder their ability to spread diseases such as dengue virus. However, researchers who wanted to know whether the bacteria could be used as a tool against West Nile virus have found that Wolbachia […]

X-rays Can be Used to Sterilize Mosquitoes

CDC-Aedes-albopictus

Since the 1950s, scientists have used radiation to sterilize insects, which are then released into the wild to mate, but no offspring are produced. Known as the sterile insect technique (SIT), this insect-control method has traditionally relied on gamma rays to sterilize the insects. However, due to concerns about terrorism, gamma-ray irradiators have become increasingly […]

Warmer Climate Does not Necessarily Mean More Mosquitoes and Diseases

mosq435

In recent years, some reports have claimed that as global temperatures rise, more areas will be affected by diseases that are spread by mosquitoes, such as malaria, dengue, and yellow fever. As temperatures rise, the logic goes, the mosquito habitat will increase and more people will be exposed to them, making them potential disease victims. […]

Study is Testing Mosquito Biting Rates and Control Methods

Grayson Brown, an entomologist at the University of Kentucky and Past President of the Entomological Society of America, is testing the biting rate of mosquitoes in residential backyards in Lexington, KY, and is also monitoring the effectiveness of mosquito control products. Due to a very wet summer and an early spring, the mosquito biting rate […]
