Researchers at the Georgia Institute of Technology have found that low-dose exposure to the pesticide sulfoxaflor may interfere with bumblebee reproduction by altering gene activity, particularly in reproductive tissues. The study showed that the pesticide changes gene expression in worker bumblebees, with the strongest effects observed in ovarian tissue. These molecular changes could reduce offspring production over time, potentially contributing to declines in bumblebee populations. Because pollinators support about one-third of global food production, the findings highlight the need to develop pest control strategies that protect crops without harming beneficial insects. Researchers say further studies could help improve pesticide use while safeguarding pollinators essential to agriculture.
