Mosquito takeover in Michigan caused by heavy rainfall
Michigan is having an unusual summer for mosquitoes. They are swarming the parks, waiting for you outside of your car and even making their way into your home. "I've been in the mosquito business for almost 40 years now this is really an impressive population," said Ned Walker, a professor of microbiology and entomology at Michigan State University. Walker is interested in the mosquito problem from a pest point of view and also from a disease point of view.
Bite back: Understanding West Nile virus in urban populations
MSU Today online
Edward “Ned” Walker, Michigan State University (MSU) professor of microbiology and molecular genetics, is examining how emerging infections behave in time and space. He will use this information to further basic biology and to develop predictive models that guide community and public health responses to emerging diseases. “Humanity seems to be facing a constant march of emerging infections,” Walker said. “Some of these diseases arrive so quickly, and many of them create social issues in addition to health challenges. When these emerging infections arrive, my colleagues and I want to know where they set up, what will be high- risk years, and if it’s possible to predict how they will behave.” Walker selected West Nile virus (WNV) to study. This virus, which is part of the Flaviviridae family, appeared in New York City in 1999 and very rapidly spread across the continental United States, reaching the West Coast by 2004. Even though it’s not discussed in the media as often as it once was, Walker said that the disease still causes serious epidemics in the United States.

Assessment of Mortality (Lc50) Of Cythion and Dieldrine by Filter Paper Contact Test on Earthworm Esenia FeotidaInternational Journal of Advance Research, Ideas and Innovations in Technology
2017 We used filter paper contact test method for obtaining LC50 for cythion and dieldrin. This Organophosphate is very poisonous, which affects the body and Growth of Earthworm.
Spatiotemporal Patterns of Host-Seeking Ixodes scapularis Nymphs (Acari: Ixodidae) in the United StatesJournal of Medical Entomology
2014 The risk of Lyme disease for humans in the eastern United States is dependent on the density of host-seeking Ixodes scapularis Say nymphal stage ticks infected with Borrelia burgdorferi. Although many local and regional studies have estimated Lyme disease risk using these parameters, this is the first large-scale study using a standardized methodology.
Toxicity of organophosphate insecticide on relative body and liver weights of miceInternational Journal of Science and Research
2013 The present study deals with the changes in relative body and liver weights of mice treated with different doses of cythion (Organophosphate insecticide) ranging from 10, 50, 100 and 500mg/kg/day diet. Cythion concentration of 500 mg/kg/day diet at 90 days produced a significant increased in body weight as compared to untreated mice.
Impact of insecticide-treated bed nets on malaria transmission indices on the south coast of KenyaMalaria Journal
2011 Besides significantly reducing malaria vector densities, prolonged usage of bed nets has been linked to decline of Anopheles gambiae ss relative to Anopheles arabiensis, changes in host feeding preference of malaria vectors, and behavioural shifts to exophagy (outdoor biting) for the two important malaria vectors in Africa, An. gambiae sl and Anopheles funestus.
Ecology and transmission of Buruli ulcer disease: a systematic reviewPLoS neglected tropical diseases
2010 Buruli ulcer is a neglected emerging disease that has recently been reported in some countries as the second most frequent mycobacterial disease in humans after tuberculosis. Cases have been reported from at least 32 countries in Africa (mainly west), Australia, Southeast Asia, China, Central and South America, and the Western Pacific.
