(wils0888@...)Aside from direct resin use, he's also interested in the leaves used by leafcutter bees. I know that leafcutter bees have definite preferences for leaves from certain plants--but do those preferences have anything to do with resins in the leaf or other antimicrobial properties?Mike Wilson, a fellow graduate student here at the University of Minnesota who works on honey bees and specifically propolis use, is interested in possible antimicrobial properties of resins used by other bees.I knew about A.C. Messer's work with tropical Chalicodoma and gave him citations for that. A brief literature search did not turn up any really promising articles for other bees, though. So I thought I would ask the beemonitoring group if you know about any other articles regarding antimicrobial properties of resins used by solitary bees.
Mike- I ll send along my paper from decades ago that showed antimicrobial effects of representative mandibular gland secretions of bees. What was needed thenMessage 2 of 2 , Oct 17View Source
Mike- I’ll send along my paper from decades ago that showed antimicrobial effects of representative mandibular gland secretions of bees. What was needed then and still needed now is quantification of chemicals in the nest cell atmosphere to relate to concentrations needed to inhibit growth of known pathogens of bees. As they say ”the dose is the toxin”. That becomes much easier today with SPME sampling technologies. I think you will also find much more literature looking for individual components, at least of conifer resins (e.g. alpha-pinene) or the tree disease literature.
