In beekeeping, the Demaree method is a swarming prevention method. It was first published by George Demaree (1832–1915) in an article in the American Bee Journal in 1892. [ 1 ] Demaree also described a swarm prevention method in 1884, but that was a two-hive system that is unrelated to modern "demareeing".
Being nudged by the queen may help to inhibit ovarian development; in addition, the queen eats any eggs laid by workers. [84] Furthermore, temporally discrete production of workers and gynes (actual or potential queens) can cause size dimorphisms between different castes, as size is strongly influenced by the season during which the individual ...
Queen rearing is the process by which beekeepers raise queen bees from young fertilized worker bee larvae. The most commonly used method is known as the Doolittle method. [ 16 ] In the Doolittle method, the beekeeper grafts larvae, which are 24 hours or less of age, into a bar of queen cell cups.
There is little advantage in adaptations that permit successful competition with other organisms, because the environment is likely to change again. Among the traits that are thought to characterize r-selection are high fecundity, small body size, early maturity onset, short generation time, and the ability to disperse offspring widely.
In evolutionary biology, parental investment is the expenditure of time and effort towards rearing offspring that benefits the offspring's evolutionary fitness at a cost to parents' ability to invest in other components of the species' fitness. Parental care requires resources from one or both parents that increases the fitness of their ...
The queen excluder continues to retain the laying queen in the lower colony while the combined colony incubates the grafted queens. The queen cells will be removed before they hatch and transferred to mating nucs. Following the removal of the ripe queen cells the cloake board can be removed to re-establish the single united colony.
New queens can be killed by the hive. Therefore, the death of a queen in winter is dangerous for a hive and can be expensive for a beekeeper. Queen excluders are used with some queen breeding methods, especially as a way to allow queen cells to be built in the same hive with an existing queen, or as a way to house multiple queens in the same hive.
Charles Darwin considered the evolution of eusociality a major problem for his theory of natural selection.In The Origin of Species, he described the existence of sterile worker castes in the social insects as "the one special difficulty, which at first appeared to me insuperable and actually fatal to my whole theory".
