This is the first study where the systematic application of theories and techniques used in mammalian sperm cryopreservation have been applied to honey bee (Apis mellifera L.) semen as a means to improve postthaw viability of cryopreserved sperm. Six newly designed diluents, three cryoprotectants (dimethyl sulfoxide, DMA, glycerol), and five diluent:semen ratios (1:1, 3:1, 6:1, 9:1, and 12:1) were...
This study was conducted to determine if European, Africanized, and hybrid honeybees differ in susceptibility to Varroa infestation and to determine if Varroa differentially reproduce on different types of brood.
