Abstract – The rich variety of native honeybee subspecies and ecotypes in Europe offers a good genetic
resource for selection towards Varroa resistance. There are some examples of mite resistance that have developed
as a consequence of natural selection in wild and managed European populations. However, most
colonies are influenced by selective breeding and are intensively managed, including the regular use of miticides.
We describe all characters used in European breeding programs to test for Varroa resistance. Some of
them (e.g., mite population growth, hygienic behavior) have been implemented in large-scale selection programs
and significant selection effects have been achieved. Survival tests of pre-selected breeder colonies
and drone selection under infestation pressure are new attempts to strengthen effects of natural selection
within selective breeding programs. Some perspectives for future breeding activities are discussed.
