Development of cryopreservation protocols for honey bee semen is hampered by the lack of validated laboratory tests that allow the prediction of in vivo performance of frozen-thawed semen. Here we analyzed correlations between seven in vitro tests and indicators of semen performance after insemination. These tests included measures of motility, cell(More)
Honeybee biodiversity is under massive threat, and improved methods for gamete cryopreservation could be a precious tool for both the in situ- and ex situ-conservation of subspecies and ecotypes. Recent cryoprotocols for drone semen have improved the viability and fertility of frozen-thawed semen by using increased diluent:semen-ratios, but there is still(More)
Centrifugation of Apis mellifera L. drone semen is a necessary step in the homogenization of semen pools for the enlargement of the effective breeding population, as well as in the collection of semen by the so-called washing technique. It is also of interest for the removal of cryoprotectants after cryopreservation. The adoption of methods involving semen(More)
