Wild bee colonies face multiple threats including pesticide exposure, habitat loss and disease, with individual and colony-level welfare affected by neonicotinoids and other agrochemicals.
Wild bee colony welfare depends on access to pesticide-free foraging habitat. Sub-lethal neonicotinoid exposure impairs learning and navigation that bees depend on for foraging success, reducing colony nutrition and fitness without causing obvious deaths. Pesticide reduction through integrated pest management and organic farming, combined with wildflower habitat creation, directly benefits individual bee welfare and colony survival.
