Persistent exposure to mite pests, poor nutrition, pesticides, and pathogens threaten honey bee survival. In healthy colonies, the interaction of the yolk precursor protein, vitellogenin (Vg), and endocrine factor, juvenile hormone (JH), functions as a pacemaker driving the sequence of behaviors that workers perform throughout their lives. Young bees perform nursing duties within the hive and h...
Abstract Managed honey bee populations have fluctuated over the past several decades in U.S. While a single factor has not been identified for these losses, interaction between multiple biotic and abiotic stressors suggested to be responsible. Of major concern are invasive parasite pathogen species as well colony management. A often suffers from harmful agents, that may act synergistically caus...
The honeybee pathogens Nosema ceranae and deformed wing virus (DWV) cause the collapse of honeybee colonies. Therefore, it is plausible that these two pathogens act synergistically to increase colony losses, since N.ceranae causes damage to the mid-gut epithelial ventricular cells and actively suppresses the honeybees' immune response, either of which could increase the virulence of viral patho...
