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.
Suzanne Batra introduced the term "eusocial" [1] after studying nesting in Halictid bees including Halictus latisignatus, [2] pictured.. The term "eusocial" was introduced in 1966 by Suzanne Batra, who used it to describe nesting behavior in Halictid bees, on a scale of subsocial/solitary, colonial/communal, semisocial, and eusocial, where a colony is started by a single individual.
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".
Gesell asserted that all children go through the same stages of development in the same sequence, although each child may move through these stages at their own rate [3] Gesell's Maturational Theory has influenced child-rearing and primary education methods since it was introduced. [4] [5]
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.
In 2013 she published a chapter entitled "Infant Rearing in the Context of Contemporary Neuroscience" in the Handbook of Child Wellbeing, eds. Korbin and Asher, published by Springer. She is a senior research fellow of the Institute for the Study of Children, Families and Social Issues, Birkbeck , University of London , and of the Tavistock and ...
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.
