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 ...
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
The bees algorithm [2] [9] mimics the foraging strategy of honey bees to look for the best solution to an optimisation problem. Each candidate solution is thought of as a food source (flower), and a population (colony) of n agents (bees) is used to search the solution space.
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 ...
The host has evolved some strategies to cope with the colony damage, such as imprisonment of the invader, patrolling and removal of beetle's eggs. [5] [6] Small hive beetle can cause significant economic loss on bee colony, stored honey and package bee production. [7] Biological control method includes uses of fungi and fire ant.
