I have been asked by Matt Allan, editor of BEE BIZ to ask the following questions of members in BEE-L. They are queries which have been submitted to him by readers of Bee Biz, to which he cannot find imediate solutions. Any replies will be sent on to him by return Apistan and Bayvarol kill braula as well as varroa. This is an advantage to commercial honey producers. What is the period of the egg to pupal stages of braula? Is six or eight weeks enough to ensure that all braula are exposed to the acaricide? What is the specific heat of beeswax the latent heat of fusion of beeswax the specific heat of honey. Many thanks to BEE-L members in advance for the help offered.
