Grafting, 1870, by Winslow Homer — an example of grafting. Fruit tree propagation is usually carried out vegetatively (non-sexually) by grafting or budding a desired variety onto a suitable rootstock. Perennial plants can be propagated either by sexual or vegetative means.
The queen is the only bee in a colony that has fully developed ovaries; she secretes a pheromone that suppresses the normal development of ovaries in all of her workers. [97] Beekeepers use the ability of the bees to produce new queens to increase their colonies in a procedure called splitting a colony. [98]
Artificial bee colony (ABC) algorithm is an optimization technique that simulates the foraging behavior of honey bees, and has been successfully applied to various practical problems [citation needed]. ABC belongs to the group of swarm intelligence algorithms and was proposed by Karaboga in 2005.
Each time an artificial bee visits a flower (lands on a solution), it evaluates its profitability (fitness). The bees algorithm consists of an initialisation procedure and a main search cycle which is iterated for a given number T of times, or until a solution of acceptable fitness is found. Each search cycle is composed of five procedures ...
They can be separated from other bee families by the presence of two subantennal sutures on the face, a primitive trait shared with the sphecoid wasps. Many groups also have depressions or grooves called "foveae" on the head near the upper margin of the eyes, another feature seen in sphecoids , and also shared by some Colletidae .
A frame taken out of a Langstroth hive seen on the left of the picture. Before the dimensions of bee space were discovered, bees were mostly hived in skeps (conical straw baskets) or gums (hollowed-out logs that approximated the natural dwellings of bees), or in box hives (a thin-walled wooden box with no internal structure).
Swarming is a honey bee colony's natural means of reproduction.In the process of swarming, a single colony splits into two or more distinct colonies. [1]Swarming is mainly a spring phenomenon, usually within a two- or three-week period depending on the locale, but occasional swarms can happen throughout the producing season.
A beehive is an enclosed structure where some honey bee species of the subgenus Apis live and raise their young. Though the word beehive is used to describe the nest of any bee colony, scientific and professional literature distinguishes nest from hive.
