Honey bee health
Honey bee health covers the survival of managed and wild Apis mellifera colonies, threatened chiefly by Varroa destructor mites, pathogens, poor nutrition, and pesticides, with US annual losses averaging about 30 percent since 2006.
Honey bee life cycle
Honey bee life cycle: complete metamorphosis of Apis mellifera through egg, larva, pupa, and adult. Queen 16 days, worker 21, drone 24; royal jelly feeding determines queen caste; brood nest kept at 34–36°C.
Honey bee subspecies and races
Honey bee subspecies and races: geographically distinct, interfertile populations of Apis mellifera, grouped into lineages A, C, M, O, Y; 20 to 33 recognized; identified by wing morphometrics and DNA; examples include ligustica, mellifera, carnica, scutellata.
Honey extraction
Honey extraction removes liquid honey from the comb by uncapping cells and spinning frames in a centrifugal extractor, invented by Francesco de Hruschka in 1865; alternatives include crush-and-strain and pressing.
Honey extractor
Honey extractor: machine using centrifugal force to spin honey out of uncapped combs, invented by Franz Hruschka, demonstrated at Brno in September 1865 and first built by Bollinger in Vienna; tangential and radial types preserve the comb for reuse.
Honey locust
Honey locust (Gleditsia triacanthos), also called sweet-locust or thorny-locust, is a thorned North American legume tree with sweet pods, thornless urban cultivars, and invasive populations in Argentina, Europe, and Australia.
Honey Nut Cheerios
Honey Nut Cheerios is a sweetened whole-grain oat breakfast cereal made by General Mills, introduced in 1979 as the second flavored Cheerios extension and the best-selling US cereal since 2009.
Honey Queen Program
Honey Queen Program: American Beekeeping Federation ambassador program (first queen Kay Seidelman, 1959) in which women 18-25, usually former state honey queens, serve a year promoting beekeeping and honey nationwide.
Honeycomb
Honeycomb: the hexagonal beeswax cell structure built by Apis honey bees for brood and honey storage; worker cells 5.2–5.4 mm, drone cells 6.2–6.4 mm, hexagon proved wax-efficient by Hales in 2001.
Honeycrisp
Honeycrisp (MN 1711) is a crisp, juicy apple cultivar released by the University of Minnesota in 1991; DNA later confirmed parentage Keepsake × MN1627. It became a top US variety, Minnesota State Fruit in 2006, and parent of Cosmic Crisp, SweeTango, and others.
Honeydew (melon)
Honeydew melon (Cucumis melo var. inodorus), a smooth-rinded winter melon with sweet green flesh; stored at 7-10°C, harvested at 10° Brix minimum, also called the Wallace melon in China.
Honeydew (secretion)
Honeydew is the sugar-rich liquid excreted by phloem-feeding hemipterans such as aphids, scale insects, mealybugs, whiteflies, and psyllids; it contains melezitose and erlose, feeds ants in trophobiotic mutualisms, and yields honeydew honey.
Honeyguide
Honeyguides (Indicatoridae), about 16–17 African and Asian near-passerine birds related to woodpeckers; the greater honeyguide guides humans to bees' nests for wax, and all species are brood parasites whose chicks kill host young with bill hooks.
Honeynut squash
Honeynut squash, a personal-sized butternut-type winter squash (Cucurbita moschata hybrid), bred at Cornell by Robinson, Jahn, and Mazourek with chef Dan Barber; released 2015, sweeter with 2-3x the beta-carotene of butternut and edible thin skin.
Honeypot ant
Honeypot ants, chiefly the North American genus Myrmecocystus and the Australian Camponotus inflatus, keep replete workers whose swollen crops store liquid food for months, feeding colonies through drought via trophallaxis.
Honeysuckle
Honeysuckle, genus Lonicera (Caprifoliaceae), about 160 Northern Hemisphere species of fragrant vines and shrubs; Japanese honeysuckle (Lonicera japonica) is a major invasive vine in North America, while Lonicera sempervirens is a native alternative.
Hong Kong flu
Hong Kong flu: the 1968-1970 influenza pandemic caused by influenza A subtype H3N2, a reassortant with an avian H3 hemagglutinin and the 1957 H2N2 N2 neuraminidase; about 1 million deaths worldwide, 100,000 in the US, mostly among people 65 and older.
