What distinguishes Russian bees from other honeybee breeds in terms of mite resistance?

Russian bees are recognized for their remarkable ability to resist parasitic mites, particularly Varroa destructor, which poses a significant threat to honeybee populations. This heightened level of resistance is attributed to several factors, including their behavioral traits such as grooming and the ability to detect and remove infested brood. Research has shown that Russian bees can demonstrate more than double the resistance to these parasitic mites compared to other honeybee breeds, making them a valuable option for beekeepers seeking to manage mite populations effectively.

In contrast, the other options do not accurately reflect the well-documented strengths of Russian bees regarding mite resistance. They are not less resistant or without any resistance at all, nor do they have an equal level of resistance when compared to other breeds. This distinctive trait is one reason why Russian bees are often preferred in areas where mite infestations are a major concern.
