A Jenter kit or Karl Jenter kit is a piece of equipment used by beekeepers to raise large numbers of queen honeybees. Rival techniques for rearing queen bees generally require grafting the honeybee larvae by hand. As such, the development of this kit by Karl Jenter is a significantly useful tool to assist in beekeeping.
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.
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 ...
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.
Microsociology is one of the main levels of analysis (or focuses) of sociology, concerning the nature of everyday human social interactions and agency on a small scale: face to face. [ 1 ] : 5 Microsociology is based on subjective interpretative analysis rather than statistical or empirical observation, [ 2 ] : 18–21 and shares close ...
Q methodology is a research method used in psychology and in social sciences to study people's "subjectivity"—that is, their viewpoint. Q was developed by psychologist William Stephenson. It has been used both in clinical settings for assessing a patient's progress over time (intra-rater comparison), as well as in research settings to examine ...
The first adoption study on schizophrenia published in 1966 by Leonard Heston demonstrated that the biological children of parents with schizophrenia were just as likely to develop schizophrenia whether they were reared by their parents or adopted [5] and was essential in establishing schizophrenia as being largely genetic instead of being a result of child rearing methods.
