Modelling long-term effects of IGRs on honey bee colonies.

Systems have been developed to monitor the direct effects of insect growth regulator (IGR) pesticide exposure on honey bee development, but there has been little work on the longer-term impact of exposure on the colony. A honey bee population model provided the opportunity to investigate the effects of short-term mortality of brood and of sublethal changes in behaviour of the surviving adults o...

Metatranscriptomic analyses of honey bee colonies

Honey bees face numerous biotic threats from viruses to bacteria, fungi, protists, and mites. Here we describe a thorough analysis of microbes harbored by worker honey bees collected from field colonies in geographically distinct regions of Turkey. Turkey is one of the World's most important centers of apiculture, harboring five subspecies of Apis mellifera L., approximately 20% of the honey be...

Honey Bee Colonies Remote Monitoring System

Bees are very important for terrestrial ecosystems and, above all, for the subsistence of many crops, due to their ability to pollinate flowers. Currently, the honey bee populations are decreasing due to colony collapse disorder (CCD). The reasons for CCD are not fully known, and as a result, it is essential to obtain all possible information on the environmental conditions surrounding the beeh...

Pathogen Webs in Collapsing Honey Bee Colonies

Recent losses in honey bee colonies are unusual in their severity, geographical distribution, and, in some cases, failure to present recognized characteristics of known disease. Domesticated honey bees face numerous pests and pathogens, tempting hypotheses that colony collapses arise from exposure to new or resurgent pathogens. Here we explore the incidence and abundance of currently known hone...

Factors Affecting Global Bee Health Honey Bee Health and Population Losses in Managed Bee Colonies

Retrospective study of the Nosema ceranae infection of honey bee colonies in Iran (2004-2013)

Nosemosis is the most common disease in adult bees. Nosema apis and Nosema ceranae species are agents of important economic losses to beekeepers around the world. The severity of disease at various area is different. Previously, N. apis was observed in areas with a long winter, especially in late winter and early spring. But in recent years, disease has been reported in the warm seasons. The st...
