Honey bees utilize hygienic and grooming behaviors as critical social defenses to manage colony health and limit the spread of diseases. Research from the University of Guelph demonstrates that sublethal exposure to clothianidin, a common neonicotinoid pesticide, significantly impairs these essential survival activities. The study reveals that while the Varroa destructor mite is a devastating parasite on its own, its interaction with chemical insecticides further reduces the frequency of intense grooming. This combined pressure from biotic and abiotic stressors creates a dangerous synergy that compromises the insects’ immune responses and physical stamina. Ultimately, the source emphasizes that protecting honey bee populations requires mitigating chemical exposure to preserve the natural behaviors that prevent colony collapse. #honeybees #valleybeekeeping
