Good for you, Zhiyong. Yes, the dead bee trap bashing was amusing but
not exactly informative.
 
The most important use of dead bee traps has been in the field monitoring
of pesticide poisoning on honeybees. The methods outlined in the papers
cited by Kirk and Seppo for the construction of such traps are sufficient
to have a competent sheet-metal worker make them up. We have had quite
a few made up here for pesticide trials on crops in Ontario and they have
worked well. These traps also collect Psithyrus "hotelling" in honeybee
hives.
