“…At each location, we identified the [nonnative (39)] flowering tree, Tecoma stans, a very common ornamental plant present across India which blooms throughout the year and is pollinated by A. dorsata. We therefore choose this flowering plant as our species of interest for A. dorsata visitation behavior, and made all observations and collections during morning bee visitation times for this species (40). At each site, we observed multiple colonies (SI Appendix, Table S1), but could not assign collected bees to specific colonies.…”

While the impact of air pollution on human health is well studied, mechanistic impacts of air pollution on wild systems, including those providing essential ecosystem services, are largely unknown, but directly impact our health and well-being. India is the world’s largest fruit producer, second most populous country, and contains 9 of the world’s 10 most polluted cities. Here, we sampled Giant Asian honey bees, Apis dorsata, at locations with varying air pollution levels in Bangalore, India. We observed significant correlations between increased respirable suspended particulate matter (RSPM) deposition and changes in bee survival, flower visitation, heart rate, hemocyte levels, and expression of genes related to lipid metabolism, stress, and immunity. Lab-reared Drosophila melanogaster exposed to these same sites also exhibited similar molecular and physiological differences. Our study offers a quantitative analysis on the current impacts of air pollution on insects, and indicates the urgency for more nonhuman studies to accurately assess the effects of pollution on our natural world.
