I have many pairs of reading glasses, including those compact ones which I love because they are so low-profile I can wear them and still drive my forklift without crashing into things. The reason I made the point I did is that I found them inadequate for getting a truly accurate count of mites on drop boards when accuracy is important (not always). The closest I have come to a real count, done right, is around 80% using just reading glasses, and sometimes poorer than that. That is after counting scrupulously and also after much practice, too. I always use a magnifier light now. Now, what degree of accuracy do we really need? I assume that if we are to going use the recommendations of researchers as a benchmark, that they did their homework and know exactly which mites to count and which not to count and don' miss many that are on edge or in debris -- so I assume that they are counting more mites than most beekeepers. Maybe twice as many or more. They also have grad students to do the grunt work like counting, and we all know that grad students are very studious and have nothing better to do than count each board twice. As a result, when researchers say, "25 mites" is borderline (or some such) and the beekeeper looks at the same board and sees 5 of the 25 (no kidding), what is going to happen? Of course a prudent beekeeper is not going to allow his/her hives within 50% of published thresholds (right?), BUT if his/her count is off by 50% or more??? On the low side! I happen to be writing about these very topics in my diary these days and what I get around to posting here is just a portion of it and largely points I want to receive some debate on. I have much more detail at: http://www.honeybeeworld.com/diary/ BTW, my drops today are half what they were the first day -- and I used the magnifier light AND reading glasses. *********************************************** The BEE-L mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
