...was renamed after the abrupt and disturbing vanishing of Western honeybee colonies here in North America, yet the same occurrence was noticed in Europe in areas such as France and the Netherlands (Wikipedia, 2014). The shortage in honeybees and their natural pollination services has led to an increase in farmers having to rent pollination services to service their crops. There are many factors to blame for the shortage of honey bees, for example, pesticides and insecticides such as neonicotinoids, malnutrition, pathogens, genetic factors, immunodeficiencies, loss of habitats, and declining beekeeping practices, antibiotics, and miticides. Some other causes of CCD are contamination, parasite loads in bees and brood, nutritional fitness of adult bees, stress levels, and a total lack of genetic diversity (Sutphin, 2014). The focus for this particular case study will be on neonicotinoids, antibiotics, and they were developed because at the time, they showed less of a toxic effect on humans and crops, as compared to organophosphate and carbonate insecticides. The mysterious, yet abrupt disappearance of honey bees from the beehive is known as colony collapse disorder or CCD. The disorder used to be known as disappearing disease, May disease, and even fall dwindle disease yet was given its current name, Colony Collapse Disorder, late in 2006. It was renamed after the abrupt and disturbing vanishing of Western honeybee colonies here in North America, yet the same occurrence was noticed...

...Using Instrumental Insemination to Fight Colony Collapse of Honey Bees What Is Colony Collapse • Colony collapse disorder (CCD) is a phenomenon in which worker bees from a European honey bee colony abruptly disappear. • While such disappearances have occurred throughout the history of apiculture, and were known by various names o Disappearing disease o Spring dwindle o May disease o Autumn collapse o and fall dwindle disease), • The syndrome was renamed colony collapse disorder in late 2006 in conjunction with a drastic rise in the number of disappearances of western honey bee colonies in North America. • Colony collapse disorder is significant economically because many agricultural crops worldwide are pollinated by European honey bees. • According to the Agriculture and Consumer Protection Department of the Food and Agriculture Organization of the United Nations, the worth of global crops with honeybee’s pollination was estimated to be close to $200 billion in 2005. Honey Bee and Colony Design • In each colony the three different types of bees each have the same basic structure. • Worker Bees are sterile females responsible for maintaining the health and sanitation of the hive. • Clean and maintain cells and hive – Remove dead – Dispatch and/or expel excess drones after breeding – Fan the beehive to regulate temperature ...

...for the food or ecosystem aspect, but for jobs for hundreds of thousands of people. The bee population is dropping too fast and humans are partially to blame for that. A third of all honeybee colonies were wiped out in the U.S. in 2007 due to the colony collapse disorder (Benjamin, Alison). The disorder is still not fully understood, but many people think that things like pesticide use on farms is one of a few main reasons why this disorder started. Pesticide that are used on farms, meant to kill pests can harm the honey bees needed for pollination (NRDC). While global warming may not be believed by everyone, studies show that “global warming has caused flowers to bloom earlier or later than usual, when the pollinators come out of hibernation, the flowers that provide the food they need to start the season have already bloomed” (NRDC). When this happens the bees are unable to get the food they need to survive the beginning of the season which causes some of them to die due to starvation. The final cause for the colony collapse disorder is habitat loss, “which is brought about by development, abandoned farms, growing crops without leaving habitat for wildlife, and growing gardens with flowers that are not friendly to pollinators” (NRDC). The colony collapse disorder is a big problem for the loss of bee population, while we cannot be completely at fault, it seems as if human errors are a main cause for the massive decline in the honey bee population in the last fifteen years. Without...

...This happened ,because inserting foreign gene in an existing DNA sample might damage the parental DNA by interference with gene expression ( Smith 15). However a different analytic study and data were collected on European honeybee, Apis mellifera, which is an important pollinator to a lot of plants in Europe ( Fairbrother, et al. 3 ). In 2006 a report was made about thousands of bees being lost and colonies are collapsing, therefore scientists wanted to take a closer look to analyse the problem.Scientists suggested a range of causes to this loss of bees to name a few, pesticides, genetically modified plants, habitat fragmentation as was studied in the monarch butterflies, and introduced diseases or predators( Fairbrother, et al 4). After the analysis it was found that Neonicotinoid insecticides are the primary cause of their death, which are a neurotoxic drugs that lead to paralysis and death of insects for crops protection( Fairbrother, et al 5). The biological mechanism behind it is that acetylcholine receptors (nAChRs), blocking the neural receptors and causing paralysis and death to insects. The secondary cause of death was GM food, which is engineered...

...INTRODUCTION Our ecosystem shows interaction between different organisms. Every living organism has a vital role in functioning of ecosystem. Three most common participants in the ecosystem are Plants, Insects and Birds. The common birds that are found in my locality are cuckoo, common house sparrow, parrot, eagle, owl and blue rock pigeon. The common plants that are found in our area are tamarind, gulmohar, papaya, tulsi, neem, banyan, and banana. The common insects that are found are earthworms, caterpillars, butterflies, housefly, dragon flies, ants, cockroach, mosquitoes, grasshopper, ladybug, honeybee and spiders. Grass is eaten by insects which are in turn eaten by birds. This represents a food chain. Plants provide a home for birds and insects provide food for birds. In other words birds are associated with plants and feed on insects - insects feed on plants and are preyed upon by birds. Apart from these two way associations there also exists an intriguing three way association among birds, plants and insects. PLANTS Plants are one of five big groups (kingdoms) of living things. Plants include familiar types such as trees, herbs, bushes, grasses, vines, ferns, mosses, and green algae. The scientific study of plants is known as botany. A plant needs sunlight, carbon dioxide, minerals and water to make food. A green substance in plants called chlorophyll traps the energy from the Sun needed to make food. Chlorophyll is mostly found in leaves. Following are the...

...lifehistory traits as regards temperature and the environment shows that the species possesses such plasticity and genetic variability that this could give rise to the selection of development cycles suited to new environmental conditions. Although we do not know the precise impact of potential environmental changes on honey bees as a result of climate change, there is a large body of data at our disposal indicating that environmental changes have a direct influence on honey bee development. In this article, the authors examine the potential impact of climate change on honey bee behaviour, physiology and distribution, as well as on the evolution of the honey bee’s interaction with diseases. Conservation measures will be needed to prevent the loss of this rich genetic diversity of honey...

AGRICULTURE TAKES A BIG BITE: THE ECOLOGICAL FOOTPRINT OF THE GLOBAL FOOD SYSTEM After air and water, food is the most essential resource people require to sustain themselves. These resources are provided by the layer of interconnected life that covers our planet: the biosphere. Yet the way the food system provides food often severely damages the health of the biosphere through soil and aquifer depletion, deforestation, aggressive use of agrochemicals, fishery collapses, and the loss of biodiversity in crops, livestock, and wild species. The global food system has become such a dominant force shaping the surface of this planet and its ecosystems that we can no longer achieve sustainability without revamping the food system. At the same time sustainable food systems provide great hope for building a sustainable future—a future in which all can lead satisfying lives within the means of the biosphere. In this brief, we use Ecological Footprint analysis to document the current food system’s demand on the biosphere. Ecological Footprint accounts track the area of biologically productive land and water needed to produce the resources consumed by a given population and to absorb its waste. The Ecological Footprint...

But in agriculture, unlike other industries where women were viewed as temporary workers, women’s employment did not end with the war. Instead, the expansion of agriculture and a steady decrease in the number of male farmworkers combined to cause the industry to hire more women in the postwar years...
