Furthermore bees specifically are particularly efficient with it being estimated that they are the sole pollinators for 50% of the approximate 80% of flowering plants which rely on insects for pollination (Bradbear, 2009). Their efficiency is further illustrated by the fact that a single colony containing 25,000 forager bees is able to pollinate 250 million flowers per day (Bradbear, 2009). As a result of this it can be seen that bees are hugely important as pollinators with many species of flower being completely dependent on them. Furthermore, the importance of bees extends beyond ecological diversity; certain types of bees are hugely important economically. In addition to pollinating a large variety of fruit and vegetables, bees produce Honey; together this results in them having an estimated value of service of £200m a year in the UK (National Audit Office (NAO), 2009). Overall it can be seen that bees are of significant importance that any decrease in population should be treated with concern, as a result of this a large quantity of research has been conducted into identifying possible

This recent outbreak of widespread bee deaths is not the first depletion of bee colonies in recorded history, which makes the source of CCD less, rather than more

In the book “ The Secret Life Of Bees “ by Sue Monk Kidd , shows a lot a

Bee decline is an increasing issue in the United states of America. An article written by the University of Vermont reveals a map of over 139 troubled zones for the population of bees and why they might be endangered. The University of Vermont is a well-respected establishment when it comes to research and Agriculture.

Of particular interest is the fact that, despite the risk to native fauna and flora, honey produced by the European honey bee is a major industry

According to the article, Honey Bee Heath and Colony Collapse Disorder, honey bees around the U.S are slowly and puzzlingly disappearing. This slow disappearance of the honey bee population is caused by a disorder known as Colony Collapse Disorder (CCD.) Colony Collapse Disorder causes adult honey bees to completely “vanish” leaving behind only the queen bee along with immature bees. Although this disease is receiving a lot of attention and research on CCD is taking place, the causes and treatments for Colony Collapse Disorder are still undefinable as well. Some may ask, “Who cares? Why is it important that bees are disappearing?” It is important because bees are the foundation to U.S agriculture and they are vital to worldwide economic stability which is why finding the cause and treatment for CCD is a top priority for scientists and researchers around the world.

Debates have been that the use of neonicotinoids began to deteriorate bee hives bee keepers are dependent on. The decline in productivity may have been caused by neonic, however an explanation has yet to be confirmed. It is believed that media have

Bees are important pollinators of many plants in the ecosystem (2). Recently, the decline in the number of bees in North America and Europe has shifted the research focus of many ecologists towards pesticide use (2). The impacts of pesticides on bees and other pollinators can have a major influence on honey production and biodiversity.

From around the year 2006, many bee farmers in the U.S.A and some parts of Europe started reporting sharp declines in their bee stocks. The reason for this declining numbers was not known and therefore scientists named it colony collapse disorder (CCD). Colony collapse disorder (CCD) is a not a very old phenomena and it became popular when large number of bee colonies started disappearing. The disappearing was mysterious since no dead bees were found in or around the beehives after a colony’s number was reported to have gone down or vanished. This prompted a lot of study and investigations to uncover the mystery and to establish possible remedies. Among the many reasons for the causes of the CCD

One of the largest responsibility for any beekeeper is to ensure that their bees are healthy. This means that Integrated Pest Management is a necessity to ensure a healthy beehive. The pros of Integrated Pest Management are decreased use of chemicals in the beehive, more sustainable, more economical in long run, less chance of hive product contamination, less exposure by beekeeper to chemicals and extends the useful life of chemicals used by lengthening time between applications. The cons of Integrated Pest Control are additional time and commitment required to implement, often requires multiple strategies and evaluation required. One disease and one pest that are extremely devastating to any beehive is American Foulbrood and wax moths.

“There is a strong scientific consensus that bees are exposed to neonicotinoid pesticides in the fields and suffer harm from the doses received, according to a new analysis of all the scientific evidence to date.” (Carrington, 2015). I will argue the idea that the exposure to the neonicotinoid insecticides are one of the key causes of the population declination in bees. According to many studies, neonicotinoid insecticides physically harm bees as they inhibit their nervous system and they can no longer navigate their way home (Fischer et al, 2014). Bees are also crucial for the pollination of many crops around the world, without them, a great percent of our agricultural practices would suffer

The method used to acquire the data is appropriate because the phenomenon is being observed in a wide range of areas and not only one area. Furthermore, a large sample was used 200-500 bees were used therefore suggesting that the data is reliable. By doing this sort of sampling they wanted to observe whether there were common factors, which are present in CCD, present in bee colonies separated by large distances

To understand the relative changes in toxic metal content between bee bread, propolis and honey in regard to pollen (outside environment), we need to have an insight into the process of food preparation for larvae and pupae, and to know how the bee's themselves develop in their larval and pupal forms.

Epigenetics can be hereditable or environmental factors that affect the expression of genes and lead to changes in gene expression. Unlike genetics, epigenetics does not only have to do with which genes are passed down to the offspring and the DNA sequence. The environmental conditions of the offspring’s parents impact the genes in their eggs and sperms by “switching on” certain genes and “switching of” others (Dowshen). Since the genes expression of the gametes are affect, the phenotypes of the offspring will change. Even in a person’s lifetime, environmental factors such as stress, chemical exposure, and diet can continue to impact gene expression through DNA methylation. During DNA methylation, a methyl group is randomly added to a 5-carbon cytosine ring, making 5-methylcytosine and these groups inhibit transcription. (Cheriyedath). Due the fact that transcription is not possible, the expressing of the genes in that section of the DNA strand will be suppressed. The attachment of the methyl group to DNA is not determined, which means that

Honey bees, feared by the misinformed and admired by the intelligent, are dying. The interest in bees from many environmentalists is not for a sudden cause, as this issue is not new to the world. Honey bees as a population have been in decline for years but have yet to reach the endangered species list anywhere in the United States except for Hawaii. Many people kill bees that buzz around joyfully, simply because they are afraid of being stung by them; however, a vast majority of bees do not sting and the others do not care. This unfortunate commonality is not even one of the top causes of the worldwide epidemic of honey bees. Although bees are jokingly idolized on the internet in pictures and videos as a result of a popular children’s movie, their population decline is in fact quite serious. Honey bees and other pollinators like birds and insects ensure the pollination of flowering plants and crops all around the globe. Not only do honey bees pollinate plants that produce the foods that humans eat, but they also pollinate trees that produce clean oxygen for Earth. Without honey bees, the world as we know it could soon end, due to carbon dioxide pollution and lack of farmable foods. The population of honeybees and other important pollinator-bee species is dwindling due to a dilemma known to scientists as colony collapse disorder (CCD) because of the use of bee-killing pesticides, known as neonicotinoids, the decrease of flower meadows in the world, and the general increase
