> Subj: trap-nests and carpenter bees > Hello, Doug Yanega told me about your inquiry. I have played around with trap nests for Xylocopa. Are you interested in making them so you can observe the in-nest behavior or do you simply want a bunch of nests? Both types are possible. I will look up some of the nest dimension information for you this weekend and get back to you. But because my work was done in Arizona you will want to modify the entrance and tunnel dimensions to the species you plan on studying. I can tell you that we had the best luck using sugar maple as the wood probably because the tunnels were very smooth, not rough as softer woods seem to create. I'll write later this weekend with more information. Bob Minckley Univ. of Kansas-- -------(please include "RM" in subj header of mail to this user)-------- Robert L.
