Separate studies on bumble bees and mason bees exposed to imidacloprid add to the body of evidence that wild bees may be particularly vulnerable to neonicotinoid insecticides.
In a recent study, flower shape played a role in defecation patterns for common eastern bumble bees (Bombus impatiens). Researchers say this could reveal a disease transmission route affecting bee populations.
New research shows traps with eugenol and phenethyl propionate—and leaving out geraniol—remain effective in catching Japanese beetles but significantly reduce bycatch of native bees. Plus, entirely green, brown, black, or red traps are least attractive to native bees.
