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.
Bumble bee nests can be hard to find and study, so researchers hope they can create artificial nest boxes for them to use and be observed more easily. But will bumble bees use such boxes? New research offers some clues about optimal design and placement of bumble bee "domiciles."
A review of existing research on floral resource competition between managed honey bees and wild bees shows gaps in our knowledge about such interactions and calls for further research to better inform decisions on honey bee management and pollinator protection.
