Life Cycles: Egg to Bee Free
FREE LIFE CYCLES: EGG TO BEE PDF Camilla de La Bedoyere | 24 pages | 01 Mar 2012 | QED PUBLISHING | 9781848355859 | English | London, United Kingdom Tracking the Life Cycle of a Honey Bee - dummies As we remove the frames, glance over the thousands of busy bees, check for brood, check for capped honey, maybe spot the queen… then the frames go back in their slots and the hive is sealed up again. But in the hours spent away from our hives, thousands of tiny miracles are happening everyday. Within the hexagonal wax cells little lives are hatching out and joining the hive family. The whole process from egg to adult worker bee takes around 18 days. During the laying season late spring to summer the Queen bee is capable of laying over eggs per day. Her worker bees help direct her to the best prepared comb and she lays a single egg in each hexagon shaped cell. The size of the cell prepared determines the type of egg she lays. If the worker bees have prepared a worker size cell, she Life Cycles: Egg to Bee lay a fertilized egg. This egg will produce a female worker bee. If the worker bees have prepared a slightly larger cell, the queen will recognize this as a drone cell and lay an unfertilized egg. This will produce a male drone bee. It is the workers and not the queen that determine the ratio of workers to drones within the hive. In three days the egg hatches and a larva emerges. It looks very similar to a small maggot. -

Colony Collapse Disorder in relation to human-produced toxins: What’s the buzz all about? Available at: http://www.sawyoo.com/postpic/2013/09/honey-bee-hives_77452.jpg Last accessed: 17/04/2017 Abstract: p2 Introduction: p3 Insecticides: p5 Herbicides & fungicides: p7 Miticides & other preventative measures: p9 “Inactive” ingredients: p10 Synergies between pesticides: p11 Conclusions: p12 Discussion: p12 References: p14 1 Abstract In recent years, the global population of pollinating animals has been in decline. The honey bee in particular is one of the most important and well known pollinators and is no exception.The Western honey bee Apis mellifera, the most globally spread honey bee species suffers from one problem in particular. Colony Collapse Disorder (CCD), which causes the almost all the worker bees to abandon a seemingly healthy and food rich hive during the winter. One possible explanation for this disorder is that it is because of the several human produced toxins, such as insecticides, herbicides, fungicides and miticides. So the main question is: Are human-produced toxins the primary cause of CCD? It seems that insecticides and, in particular, neonicotinoid insecticides caused increased mortality and even recreated CCD-like symptoms by feeding the bees with neonicotinoids. Herbicides seem relatively safe for bees, though they do indirectly reduce the pollen diversity, which can cause the hive to suffer from malnutrition. Fungicides are more dangerous, causing several sublethal effects, including a reduced immune response and changing the bacterial gut community. The levels of one fungicide in particular, chlorothalonil, tends to be high in hives. Miticides levels tend to be high in treated hives and can cause result in bees having a reduced lifespan. -
Hanson's Garden Village Edible Fruit Trees
Hanson’s Garden Village Edible Fruit Trees *** = Available in Bare Root for 2020 All Fruit Trees Available in Pots, Except Where Noted APPLE TREES Apple trees are not self fertile and must have a pollination partner of a different variety of apple that has the same or overlapping bloom period. Apple trees are classified as having either early, mid or late bloom periods. An early bloom apple tree can be pollinated by a mid bloom tree but not a late bloom tree. A mid bloom period apple could be used to pollinate either an early or late bloom period apple tree. Do not combine a late bloomer with an early bloom period apple. Apple trees are available in two sizes: 1) Standard – mature size 20’-25’ in height and 25’-30’ width 2) Semi-Dwarf (S-M7) – mature size 12’-15’ in height and 15’-18’ width —————————————————————–EARLY BLOOM—————————————————————— Hazen (Malus ‘Hazen’): Standard (Natural semi-dwarf). Fruit large and dark red. Flesh green-yellow, juicy. Ripens in late August. Flavor is sweet but mild, pleasant for eating, cooking and as a dessert apple. An annual bearer. Short storage life. Hardy variety. Does very well without spraying. Resistant to fire blight. Zones 3-6. KinderKrisp (Malus ‘KinderKrisp’ PP25,453): S-M7 (Semi-Dwarf) & Standard. Exceptional flavor and crisp texture, much like its parent Honeycrisp, this early ripening variety features much smaller fruit. Perfect size for snacking or kid's lunches, with a good balance of sweet flavors and a crisp, juicy bite. Outstanding variety for homeowners, flowering early in the season and ripening in late August, the fruit is best fresh from the tree, hanging on for an extended period. -

www.nature.com/scientificreports OPEN Mitochondrial genomes illuminate the evolutionary history of the Western honey bee (Apis mellifera) Erik Tihelka1*, Chenyang Cai2,3*, Davide Pisani3,4 & Philip C. J. Donoghue3 Western honey bees (Apis mellifera) are one of the most important pollinators of agricultural crops and wild plants. Despite the growth in the availability of sequence data for honey bees, the phylogeny of the species remains a subject of controversy. Most notably, the geographic origin of honey bees is uncertain, as are the relationships among its constituent lineages and subspecies. We aim to infer the evolutionary and biogeographical history of the honey bee from mitochondrial genomes. Here we analyse the full mitochondrial genomes of 18 A. mellifera subspecies, belonging to all major lineages, using a range of gene sampling strategies and inference models to identify factors that may have contributed to the recovery of incongruent results in previous studies. Our analyses support a northern African or Middle Eastern origin of A. mellifera. We show that the previously suggested European and Afrotropical cradles of honey bees are the result of phylogenetic error. Monophyly of the M, C, and O lineages is strongly supported, but the A lineage appears paraphyletic. A. mellifera colonised Europe through at least two pathways, across the Strait of Gibraltar and via Asia Minor. As probably the single most signifcant pollinator of agricultural crops and wild plants and as a producer of a variety of foodstufs with nutritional, medical, and cosmetic uses such as honey and propolis, the importance of understanding the evolutionary history of Apis mellifera Linnaeus, 1758 cannot be overstated. -
Honey Bees and Climate Change
Abstract of final report Honey Bees and Climate Change Prof. Dr. Frank-M. Chmielewski, Sophie Godow For the western honey bee (Apis mellifera), weather conditions (especially air temperature, but also global radiation, precipitation intensity and wind speed) and availability of nectar are, next to factors like breeding traits and colony health, essential in determining flight activity and with it for pollination and honey yield. Thus, climate changes could affect flight conditions for bees. In Hesse, an increase in the air temperature of 0.6 K was detected compared from the period 1951-1980 to 1981-2010 (HLNUG, 2016). Climate scenarios predict a further increase of 3.9 K on average for the period 2071-2100 compared to the reference period 1971-2000 (REKLIES, 2017). This study examines the impact of a changing climate on honey bee flight and honey yield. The model BIENE, developed by the German Weather Service (Deutscher Wetterdienst, DWD, FRIESLAND, 1998), allows the classification of hours according to their (weather-related) suitability for bee flight (none at all, bad, moderate, good) as well as the calculation of a measure of potential bee flight for freely chosen periods. This purely weather-driven model, however, was not suitable for the assessment of the bee flight during the whole year, because crucial parameters were omitted from the model, especially the phenology of honey plants. The effects of climatic changes of the last decades are clearly visible on the development of these plants, especially in spring. For example, the beginning fruit tree blossom (apple, sweet cherry, sour cherry, pear) in Germany since 1961 has advanced by about 3 days per decade. -
