Honey bees at a hive entrance: one is about to land and another is fanning. Colony collapse disorder (CCD) is an abnormal phenomenon that occurs when the majority of worker bees in a honey bee colony disappear, leaving behind a queen, plenty of food, and a few nurse bees to care for the remaining immature bees. [1]
This leads to collapse of the bee colony. Within a few years, a strongly increased propagation of Nosema was observed, and its occurrence was happening all year round due to the higher resistance of N. ceranae. A higher reinfection rate of the bee colonies is assumed, since the pathogen survives longer in the external environment.
Various technologies can be applied for monitoring the bee colony and implementation of data collection phase. [2] The data collection process in PB can be classified into three groups [3] 1) apiary-level parameters (meteorological parameters and video observation); 2) colony-level parameters (temperature, humidity, gas content, sound, video, vibration of hive and weight); 3) individual bee ...
Here’s a bummer of a statistic for you: Around 30% of bee colonies disappear every year. Scientists coined the phrase "colony collapse disorder" (CCD) to describe what’s been a devastating ...
Census data shows that the number of bee colony operations rose much faster than honey production—and is up 160% since 2007. Pollination—not honey—is why the U.S. needs more bees
Nosema ceranae was first described in 1996 and was identified as a disease of Apis mellifera in 2004 in Taiwan. [4] Since its emergence in honeybees, N. ceranae has been identified in bumblebee species in South America, [5] China, [6] and England where infection studies indicate N. ceranae has a higher virulence in bumblebees than honeybees.
Chronic bee paralysis virus infection is a factor that can contribute to or cause the sudden collapse of honeybee colonies. [2] Since honeybees serve a vital role in ecological resilience , it is important to understand factors and diseases that threaten them.
Acarapis woodi is a parasitic mite that infests the trachea that lead from the first pair of thoracic spiracles. An unidentified bee illness was first reported on the Isle of Wight in England in 1904, becoming known as the 'Isle of Wight disease' (IoWD), which was initially thought to be caused by Acarapis woodi when it was identified in 1921 by Rennie.
