Abstract: Abstract Most honey bee (Apis mellifera Linnaeus, 1758) (Hymenoptera: Apidae) colonies in the United States have been exposed to the beekeeper-applied miticides amitraz, coumaphos, and tau-fluvalinate. Colonies are also often exposed to agrochemicals, which bees… read more here.

Abstract: Peroxiredoxins (PRDXs) are antioxidant enzymes proven to control the levels of reactive oxygen species (ROS) and to avoid oxidative damage in the spermatozoon. Previously, we have shown that low amounts of PRDXs are associated with… read more here.

DOI: 10.1371/journal.pone.0208630
Abstract: Honey bee (Apis mellifera) colonies invest a substantial amount of colony resources in the production of drones during the reproductive season to enable mating with virgin queens from nearby colonies. Recent studies have shown significant… read more here.

Abstract: The accurate prediction of bull fertility is of major economic importance in the dairy breeding industry. Sperm fertilizing potential is determined by their ability to reach the oocyte, complete fertilization, and sustain embryogenesis, which is… read more here.

DOI: 10.3389/fphys.2023.1107660
Abstract: Developing effective long-term sperm storage strategies to maintain activity requires an understanding of the underlying spermatophore developmental phase in drones. Here we compared the developmental processes and metabolites about seminal vesicles of drones from different… read more here.
