The worldwide losses of honey bee colonies continue to puzzle researchers and the beekeeping industry. Over the past few years, the media have frequently reported deaths of honey bee (Apis mellifera L.) colonies in the United States, Europe, and Japan. Most reports express opinions but little hard science. A recent historical survey (1) pointed out that extensive colony losses are not unusual and have occurred repeatedly over many centuries and locations. Concern for honey bees in the United… 

Colony Collapse Disorder in context

Despite an almost 50% increase in world honey bee stocks over the last century, beekeepers have not kept pace with the >300% increase with pollinator-dependent crops, and has led to great uncertainty surrounding the recent large-scale die-offs.

This review will focus on selected bee pathogens and parasites which have been demonstrated to be involved in colony losses in different regions of the world and which, therefore, are considered current threats to honey bees and beekeeping.

Colony Collapse Disorder of Honey Bee: A Neoteric Ruction in Global Apiculture

The study was undertaken to make a detailed idea on CCD, its impact, probable causes, economic importance, controversy etc by assembling the inferences of a number of global researchers.

Parasites and pesticides act antagonistically on honey bee health

Declines in honey bee populations appear to have multiple causes, the most important of which are increased exposure to parasites and pesticides, and threatens the sustainability of agricultural systems that rely on honey bee pollination.

Colony Collapse and the Consequences of Bee Disease: Market Adaptation to Environmental Change

Economic indicators of input and output markets related to managed honey bee operations and remarkably little to suggest dramatic and widespread economic effects from CCD are analyzed.

Viral impacts on honey bee populations: A review

An Overview on Honeybee Colony Losses in Buenos Aires Province, Argentina

The samples were screened for presence of several pathogens and the determination of maternal lineages was also performed, and seven out of ten colonies were positive for pathogens, but there was no high prevalence of any of them.

The puzzle of honey bee losses: a brief review.

It is insufficient to explain CCD with only bee pathology studies, so research must be conducted on a wider series of causes to understand the fate of pesticide blends and to determine ways to enhance honey bee defence to diseases and parasites.

Honey bee colony losses

Examination of the historical record shows that such extensive colony losses are not unusual, and it is crucial to make beekeeping a more attractive hobby and a less laborious profession, in order to encourage local apiculture and pollination.

A Metagenomic Survey of Microbes in Honey Bee Colony Collapse Disorder

The observation that irradiated combs from affected colonies can be repopulated with naive bees suggests that infection may contribute to colony collapse disorder (CCD).

Does infection by Nosema ceranae cause “Colony Collapse Disorder” in honey bees (Apis mellifera)?

N. ceranae is an emergent and potentially virulent pathogen of the honey bee (Apis meiiiferai) that has spread across the world in the last 10 or so years and observations of naturally infected colonies suggest that it leads to colony collapse in Spain.

Colony Collapse Disorder: A Descriptive Study

This is the first comprehensive survey of CCD-affected bee populations that suggests CCD involves an interaction between pathogens and other stress factors, and presents evidence that this condition is contagious or the result of exposure to a common risk factor.

Changes in transcript abundance relating to colony collapse disorder in honey bees (Apis mellifera)

Ribosomal fragment abundance and presence of multiple viruses may prove to be useful diagnostic markers for colonies afflicted with CCD.

The role of Varroa and viral pathogens in the collapse of honeybee colonies: a modelling approach

The model revealed that DWV initially had little effect on the colony but during late summer, as the population of DWV-transmitting mites increased, the virus caused a reduction in the number of healthy young bees entering the overwintering population, resulting in the eventual death of the colony during the winter or spring.

Effects of transgene products on honey bees (Apis mellifera) and bumblebees (Bombus sp.)

Current findings suggest that transgenic plant impacts on pollinators will depend on a case-by-case analysis of the gene concerned and its expression in the parts of the plant ingested by bees.

What's Killing American Honey Bees?

American beekeepers reported unusually high rates of colony loss in early 2007 as bees broke from their overwintering clusters. Researchers are struggling to explain what's behind this mysterious
