It had no treatments for the 2-1/2 years I had it. Why it died, I don't know. I could not open it, and never managed it. I never saw a varroa on an entrance bee for 2 years. (I saw one 2 years ago). In case you are wondering, the cells mostly measured 5.2mm. Some measured 5.3, but I haven't done a serious post mortem, other than noting there was no brood, so I assume the queen petered out. http://www.honeybeeworld.com/diary/2001/diary032901.htm http://www.honeybeeworld.com/diary/2002/diary091002.htm http://www.honeybeeworld.com/diary/2003/diary032003.htm http://www.honeybeeworld.com/diary/2003/diary041003.htm http://www.honeybeeworld.com/diary/2003/diary061003.htm > 2.added the fogger (different method of application) That idea actually came from a post on this very forum. http://listserv.albany.edu:8080/cgi-bin/wa?A2=ind9604D&L=bee-l&P=R2836 mentions it. I was looking for the original suggestion, but maybe it was in a personal communication, anyhow... Unfortunately, Dr. Pedro did not enjoy the hard questioning he got from some members of this list, and chose to go elsewhere. I appreciate the rigour dealt to anyone making claims here, but I think we could be a bit more kind sometimes. allen http://www.honeybeeworld.com/misc/ABA2003.htm Come to Edmonton for Nov 3,4,5.
