Reading the PA Outdoor news here, and an article reports that 22k acres will be sprayed with the bacteria Bacillus thuringiensis(Bt)-it will cost half a million.
Reading about it on Wikipedia looking to understand how it operates and if it will kill other insect life. Found this, "The toxicity of each Bt type is limited to one or two insect orders, and is nontoxic to vertebrates and many beneficial arthropods. The reason is that Bt works by binding to the appropriate receptor on the surface of midgut epithelial cells. Any organism that lacks the appropriate receptors in its gut cannot be affected by Bt"
Uh, aren't some insect orders pretty huge????
