Spare the bees

New research may make for better-targeted pesticides that do their job but don’t hurt beneficial insects

By
Pyrethroid pesticides could be modified with a few molecular tweaks to eliminate pests while preserving beneficial insects like bees. Those are the findings of researchers at Michigan State University’s entomology department in a study featured in the current issue of Proceedings of the National Academy of Sciences. These pesticides target a protein known as the
New research may eventually see plants created that can shake off insect damage on their own.
