Hi Teresa and All: >I know there are people from all over the world in this list, and I >would like to ask if somebody has ever used the "Neem tree" for >controlling Varroa? Adony Melathopoulos at Simon Fraser University in Canada was studying this. He used to be a regular contributor to this list, but he has not posted for a long time so I am not sure if he still is. The last time we communicated I believe he said that neem DID have control effects on the mites, but that the levels that bees could tolerate were not well enough known. Regards, Stan
