Beyond DEET: new-age mosquito control.
One mosquito genus, Culex, has been shown to transmit both WNV and SLE. ARS scientists have discovered and patented a new baculovirus--a virus specific to arthropods, called CuniNPV--that kills Culex mosquitoes. Stable and persistent, the virus is a promising candidate for development as a larvicide. The patent includes a method for transmitting a virus to the mosquitoes. The baculovirus is activated by mixing with magnesium. When the mixture is added into any body of water where mosquitoes breed, the larvae ingest it: the result is 85 to 95 percent kill after 2 to 3 days. There is no harm to other organisms or to the water. James J.
