Re. Osmia Cocoons from Yugoslavia
 
    L.Z. Stanisavljevic reported on the work done re. O. rufa and O.
    cornata.  I also noticed that he offered coccoons to anyone interested.
    I am not sure the wisdom of shipping Osmia coccons and nesting material
    possibly all over the world.  For many countries, such importation is
    downright illegal but more importantly for us interested and
    conscientious about bees and pollinators, are we wise in distributing
    Osmia species to areas where they may not native and hence, affecting
    existing pollinator populations?  Also, Osmia is known to act as host to
    a range of organisms (not necessarily parasites) including fungi
    (Ascospheara spp.), mites, flies, etc.  The intro of Osmia in a given
    area may not have any affect but the associated organisms may.
 
    I would advise caution to any proposed shipment of Osmia until more
    information is available.
