Danger to Western U.S. Lepidopteras

Contributed by Ken Philip

An entomological correspondent of mine has come up with some very disturbing information for anyone who is concerned about the long-term health of lepidoptera populations in the western U.S. Apparently the gov't is gearing up to fight gypsy moth incursions into the western states, and my correspondent said:

Although there is a species specific virus for gypsy moth, the commercial preparation of which is known as Gypchek, the USDA is planning to use the broad spectrum lepidoptericide B.t. I asked why and was told that killing at least certain other leps was considered a benefit, and that the B.t. industry is well established whereas Gypchek is not being produced in quantity.

Anyone who is worried about the impact of _collecting_ on butterfly populations should be appalled at the prospect of aerial spraying of B.t.! Obviously, Gypchek would be produced in quantity if its use were mandated, so you might consider contacting the appropriate politicians and urging them to recommend that the USDA consider switching to Gypchek.
