Abstract - Euvarroa sinhai was collected from drone brood cells of Apis florea and introduced into cages with 5 worker bees of 3 honeybee species. After 24 h the survival rates of the mites were determined. The survival of Euvarroa sinhai on Apis mellifera was 53% compared to 70% on Apis florea and 8% on Apis cerana. Surviving Euvarroa sinhai were found under abdominal sternites of the bees. Experiments under more natural conditions are required to further explore the question of whether or not Euvarroa sinhai must be considered as a new candidate for parasitism on the Western honeybee Apis mellifera.
