Mother Nature to provide an environmentally friendly method for reducing mosquitoes
Date:7/21/2010

using mosquito repellents applied to the human skin. Prof. Blaustein points out that options for all three lines of defense are often chemicals that negatively affect the environment and are of health concerns to humans. Moreover, mosquitoes often develop resistance to chemical pesticides so there is always a need to find new weapons against mosquitoes. A bacterial pesticide, Bacillus thuringiensis israeIensis, can be very effective in killing mosquito larvae in breeding habitats while having relatively minor non-target effects, but it is rather expensive and is not effective in highly organic-polluted water.

This research group's new findings of chemical identification of predator-released egg-laying repellants can be a breakthrough in providing a natural, environmentally friendly and inexpensive option to the arsenal in the first line of defense.

Blaustein adds, "While we see this as a potentially large breakthrough in developing another weapon against mosquitoes, the work, is not over. We hope this breakthrough will spur further research to chemically determine other effective predator-released chemicals, particularly ones that are long lasting and then tested for their efficacy."
