François Huber
François Huber (2 July 175022 December 1831), also known as Francis in English publications and Franz in German publications, was a Swiss entomologist who specialized in honey bees. His pioneering work was recognized all across Europe and based on thorough observation with the help of several assistants due to his blindness. Life Early life François Huber was born in Geneva on 2 July 1750 in a well respected and well-off family of merchants and bankers with important ties to Geneva, Lyon and Paris. The Huber family had members in the highest institutions in the local community and was linked to other prominent local families. The family made significant contributions to the scientific and theological literature. His great-aunt, Marie Huber, was known as a voluminous writer on religious and theological subjects, and as the translator and epitomizer of The Spectator (Amsterdam, 3 vols., 1753). His father Jean Huber (1721–1786) was a prominent member of the coterie at Ferney ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oviparity
Oviparous animals are animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, most reptiles, and all pterosaurs, dinosaurs (including birds), and monotremes. In traditional usage, most insects (one being ''Culex pipiens'', or the common house mosquito), molluscs, and arachnids are also described as oviparous. Modes of reproduction The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or fertilised eggs are spawned, and viviparity traditionally including any mechanism where young are born live, or where the development of the young is supported by either parent in or on any part of their body. However, the biologist Thierry Lodé recently divided the traditional category of oviparous reproduction into two modes that he named ovuliparity and (true) oviparity respectively. He distinguished the tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drone (bee)
A drone is a male honey bee. Unlike the female worker bee, drones do not have stingers. They gather neither nectar nor pollen and are unable to feed without assistance from worker bees. A drone's only role is to mate with a maiden queen in nuptial flight. Genetics Drones carry only one type of allele at each chromosomal position, because they are haploid (containing only one set of chromosomes from the mother). During the development of eggs within a queen, a diploid cell with 32 chromosomes divides to generate haploid cells called gametes with 16 chromosomes. The result is a haploid egg, with chromosomes having a new combination of alleles at the various loci. This process is called arrhenotokous parthenogenesis or simply arrhenotoky. Because the male bee technically has only a mother, and no father, its genealogical tree is unusual. The first generation has one member (the male). One generation back also has one member (the mother). Two generations back are two members (the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Jelly
Royal jelly is a honey bee secretion that is used in the nutrition of larvae and adult queens. It is secreted from the glands in the hypopharynx of nurse bees, and fed to all larvae in the colony, regardless of sex or caste.Graham, J. (ed.) (1992) ''The Hive and the Honey Bee'' (Revised Edition). Dadant & Sons. During the process of creating new queens, the workers construct special queen cells. The larvae in these cells are fed with copious amounts of royal jelly. This type of feeding triggers the development of queen morphology, including the fully developed ovaries needed to lay eggs. Royal jelly is sometimes used in alternative medicine under the category apitherapy. It is often sold as a dietary supplement for humans, but the European Food Safety Authority has concluded that current evidence does not support the claim that consuming royal jelly offers health benefits to humans. In the United States, the Food and Drug Administration has taken legal action against companies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queen Bee
A queen bee is typically an adult, mated female (gyne) that lives in a colony or hive of honey bees. With fully developed reproductive organs, the queen is usually the mother of most, if not all, of the bees in the beehive. Queens are developed from larvae selected by worker bees and specially fed in order to become sexually mature. There is normally only one adult, mated queen in a hive, in which case the bees will usually follow and fiercely protect her. The term "queen bee" can be more generally applied to any dominant reproductive female in a colony of a eusocial bee species other than honey bees. However, as in the Brazilian stingless bee ''Schwarziana quadripunctata'', a single nest may have multiple queens or even dwarf queens, ready to replace a dominant queen in a case of sudden death. Development During the warm parts of the year, female "worker" bees leave the hive every day to collect nectar and pollen. While male bees serve no architectural or pollinating purpo ...

Charles Bonnet
Charles Bonnet (; 13 March 1720 – 20 May 1793) was a Genevan naturalist and philosophical writer. He is responsible for coining the term ''phyllotaxis'' to describe the arrangement of leaves on a plant. He was among the first to notice parthenogenetic reproduction in aphids and established that insects respired through their spiracles. He was among the first to use the term "evolution" in a biological context. Deaf from an early age, he also suffered from failing eyesight and had to make use of assistants in later life to help in his research. Life and work Bonnet was born in Geneva, the son of Pierre Bonnet and Anne-Marie Lullin de Châteauvieux. Although originally from France, the family had been driven into Geneva by religious persecution of Protestants in the 16th century. At age seven he lost hearing which pushed him into an interest in the natural world. His schoolmates troubled him due to the hearing handicap and the parents took him out and had a private tutor.

René Antoine Ferchault De Réaumur
René Antoine Ferchault de Réaumur (; 28 February 1683, La Rochelle – 17 October 1757, Saint-Julien-du-Terroux) was a French entomologist and writer who contributed to many different fields, especially the study of insects. He introduced the Réaumur temperature scale. Life Réaumur was born in a prominent La Rochelle family and educated in Paris. He learned philosophy in the Jesuits' college at Poitiers, and in 1699 went to Bourges to study civil law and mathematics under the charge of an uncle, canon of La Sainte-Chapelle. In 1703 he went to Paris, where he continued the study of mathematics and physics. In 1708, at the age of 24, he was nominated by Pierre Varignon (who taught him mathematics) and elected a member of the Académie des Sciences.Egerton, F. N. 2006A History of the Ecological Sciences, Part 21: Réaumur and His History of Insects Bulletin of the Ecological Society of America 87(3):212–224.
