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]
Bees die far away from the dwellings, as when they leave they are too weak to return. 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 ...
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
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 ...
This series explores aspects of America that may soon be just a memory -- some to be missed, some gladly left behind. From the least impactful to the most, here are 25 bits of vanishing America ...
A dead carpenter bee Pollinator decline is the reduction in abundance of insect and other animal pollinators in many ecosystems worldwide that began being recorded at the end of the 20th century. Multiple lines of evidence exist for the reduction of wild pollinator populations at the regional level, especially within Europe and North America.
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.
