Queen bees are secretly dumping pesticide toxins into their eggs — a shocking new survival tactic that could be silently sabotaging entire colonies. When worker bees fail to filter out chemicals, the queen steps in with a risky move called maternal offloading, sacrificing her offspring’s health to protect herself. This is the first time such behavior has been documented in honeybees, and it may explain why pesticides linger in colonies even after exposure ends — potentially accelerating colony collapse during critical foraging seasons. Scientists tracked the process using nanocolonies and…
