Stan Standler and all: Just checked my mail before going to bed, 5A.M. comes early. The only research I could find with neem and varroa is being done by: Adony Melathopoulos <[log in to unmask]> Or Eric Mussen at Davis California. Eric Mussen <[log in to unmask]> Will post a complete list of findings of neem net search tommorrow. Later Jeffrey 33600 Navion Paynes Creek Ca. 96075
