This is the best news I've heard for a long time. No kidding..... a way to spare us the onslaught of more bad bugs. I'm hopeful that this will work the same for grasshoppers and maybe there can be something along these lines done for the bees but that may be too big a hope. It is extremely vital that we know what to do about Those bugs that hinder or help our food supply.
