BOH to probe mosquito control questions

At its meeting on December 9 the Board of Health (BOH) felt that they still have too many questions about the safety and efficacy of mosquito control methods and decided to put off a town vote until at least March 2009.

A primary question is whether lowering the mosquito population actually has a significant effect on reducing incidences of West Nile virus and Eastern equine encephalitis. Another question concerns the medium for spreading Bacillus thuringiensis israelensis (Bti), the bacterium used to kill mosquito larvae. The most common medium is corn, which is used so that the material will drop straight to the ground rather than blowing around in the wind. However, if the corn is genetically modified (GM) corn, organic farmers may be concerned that it will contaminate their crops.

The board will engage an expert on mosquito control to help them answer these and other questions. ∆
