Good design ideas, Trevor.
Also contact the USDA Bee Lab in Tucson, Arizona for design
specifics of the Todd dead bee trap, tested and published in the
1950s-60s by Frank Todd, S.E. McGregor, and many others. It was
used extensively to verify insecticide kills in many field and
pollination studies. It is made entirely of galvanized metal
sheeting, with a double wire screen to relieve the bee of her dead
companion on flying through it, and metal louvers covering a box
at the bottom to prevent the bees from retrieving the dead.
I will copy this message to Gloria Hoffman, local
chief-in-charge.
