Table 1. Mean ± standard error of mite infestation rates, daily mite fall and percentage of damaged mites on adult honeybee workers in colonies of A. m. scutellata and A. mellifera hybrids of European origin.

			Mean ± SE
Sites	Honeybee species	Number of colonies	Mite infestation rate/100 adult worker bees (3 replicates/colony)	Daily mite fall/colony	% damaged mites
Kenya	Apis mellifera scutellata	14	5.0 ± 1.4	18 .1 ± 2.8	21.3 ± 1.7
USA	Apis mellifera hybrids of European origin	20	14 ± 2.3	15.8 ± 3.9	21.3 ± 2.4
