Colony Collapse Disorder and Pesticides
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 was the use of harmful and dangerous pesticides. Timbrell (2002) provides a solid foundation on the effects of toxins in the body of animals with an aim of providing a scientific solution towards the problem. This paper focuses its study on these pesticides with an aim of establishing the effects of the toxins found in the insecticides that could be affecting the bees.
In CCD, honey bee colonies lose their workers under unclear circumstances (Cox-Foster et al., 2007, p. 283). It is not unusual for bees to die or colonies to be lost, but the nature and extent reported in the year 2006 was alarming. Statistics gathered in the United States alone show that 50-90% of the bees have been lost so far, due to this scientific phenomenon (Cox-Foster et al., 2007, p. 284).
Honeybees play a very major role in the pollination of plants and therefore these huge losses have become a serious concern. There are many reasons that have been floated and acclaimed to be behind CCD and they include pesticides, para...

...re many and interrelated although some contribute more towards the phenomena than others. The governments of the affected countries must set aside funds that will help in carrying out research to establish the causes of CCD. Countries not affected by this phenomenon must also take all the necessary precautions to prevent their stock of bees from declining in numbers. If necessary steps are not taken as early as now, then many nations risk losing millions of plants due to lack of pollination and eventually we could be a famine stricken world.

Think for a moment of a world without bees; a world without our buzzing friend. They might look like they barely do much to help our ecosystem. However, bees are a vital part of our agriculture and this makes it vital that we keep them around. The bee population decline in recent years is troubling for both us and our little friends. As their friends, we must do all we can in order to ensure their survival which in turn will ensure our own.
What can we actively take part in to stop the collapse of bee colonies? Bees are such a vital part of our everyday agriculture production, however, colonies are diminishing before our eyes. Colony Collapse Disorder is a massive decrease of bees in hives and it is greatly affecting our crops because bees are not distributing the necessary amount of pollen to crops in order for them to grow the maximum, most nutritious produce possible. There are many solutions that may help CCD, such as banning neonics, urban beekeeping, and interbreeding honey bees with African killer bees. The most effective way to decrease CCD is by interbreeding honey bees with a stronger specie of bees labeled African killer bees.

In Europe and even in China honeybee populations are decreasing. This has an impact on everyone in the market. It effects how they food gets to the dinner table and how much it cost to put it there. Fresh produces will eventually end up being fresh produce from across the ocean or fresh produce made in a lab. It wasn’t until October 2006 when Hackenburg came public about his bees vanishing that anybody noticed that the bees were dispersing, but still scientist can’t prove the exact cause to CCD. In America nothing has really been done yet to help the honeybees. Other countries, like Europe did at least tried to maintain the current population of honeybees by amending a law that prohibited certain types of pesticides that many be harmful to honeybees. The most important thing that could be done to protect the honeybees is stop using pesticides that are harmful to important creatures like honeybees. Just like Europe did, put a ban on harmful chemicals to honeybees, until the honeybees numbers start to increase. Another logical way to help the honeybee population is to give a tax credit to people who decide to become bee keepers since bees are very important to the US economic
Theses pesticides can cause “colony collapse disorder”, which devastates bee colonies and other surrounding colonies. Many doubt that these chemicals have anything to do with colony collapse disorder, but “the doubt some are casting on the role of these toxic chemicals in colony collapse is unconvincing to many beekeepers across the country, who have observed it all first-hand and know the patterns better than anyone.” (Judge) There is a pesticide called neonicotinoids or “neonics” that are not only toxic to bees and other pollinators, but can also wipe out whole colonies. There
But along with crops, comes along pests and when pests come, so do pesticides. Pesticides cannot tell the difference between pollinators and pests, because of this; the bees are suffering greatly. One of the biggest reasons for the bee population declining is the drastic use of one of the many pesticides “neonicotinoid”. A neonicotinoid, a type of
Pesticides are very soluble, which means they can dissolve easily. This is harmful because 50% of the U.S.’s water comes from groundwater. According to the U.S. Geological survey, (USGS), in 2001, pesticides were found in all samples from major rivers with mixed agricultural and urban land influences, and that 99% of samples in urban streams. In 1995, 23 different kinds of pesticides were found in the waters of the Puget Sound Basin in Washington, including 17 herbicides. The USGS also found that concentrations of insecticides in some Urban streams exceeded guidelines for aquatic life. Next, ⅓ of the food we eat is pollinated by bees. This includes almonds, peaches, grapes, coffee (plant), and chocolate (cacao plant). This year, bees have been declared an official endangered species. The main cause of the decline in the population of bees globally is the use of pesticides. Most insecticides are toxic to bees. This effects everyone eating food pollinated by honey bees, no matter who you are, or where you live. Lastly, soil is affected by pesticides. Heavy treatment of soil with pesticides can cause populations of beneficial soil microorganisms to decline. “According to the soil scientist Dr. Elaine Ingham, “If we lose both bacteria and fungi, then the soil degrades. Overuse of chemical fertilizers and pesticides have effects on the soil organisms that are similar to human overuse of antibiotics. Indiscriminate
Pesticides are very harmful to the bees. Although pesticide use can be prevented, they have still caused many honeybee deaths. In the TED talk “Why bees are disappearing” by Marla Spivak she presents the reasons why bee populations have been declining so rapidly over recent years. Spivak expresses, “If one of these neonics, we call them, is applied in a high concentration, such as in this ground application, enough of the compound moves through the plant and gets into the pollen and the nectar, where a bee can consume, in this case, a high dose of this neurotoxin that makes the bee twitch and die”. If a bee goes to pollinate a flower that has a pesticide within it the bee will become poisoned by it and end up dying. Even in lower doses it can still harm the bee to the point where it is unable to function well and navigate where it needs to go. This is the very bad since it can be prevented yet it is still a big cause of large bee
In recent years, millions of bees have been dying off leaving consequences for our environment. We rely on bees to pollinate 71 out of the 100 crops providing most food for the world. Animals such as cows need their food (plants) before we do, so we can then eat them, as well as plants, as our food. So without bees properly pollenating, we have no food. Global warming, habitat loss, and parasites are a few causes of bees slowly disappearing. A bee-killing insecticide known as neonicotinoids is one of the biggest causes of bees slowly dying off. It works its way into the pollen and nectar of plants, which is very toxic for the bees and kills them when they go to pollinate. This also stops the growth of plants for bees to pollinate in the first
At to start with, nobody knew why. In any case,the most recent couple of years researchers have aggregated a convincing heap of confirmation indicating a class of bug sprays called neonicotinoids. These chemicals are generally utilized as a part of business horticulture yet can effectively affect honey bees. Different pesticides are additionally adding to the toll. So are obtrusive parasites and a general decrease in the nature of honey bees' eating methodologies.
First at Harvard University, associate professor of environmental exposure biology in the Department of Environmental Health Chensheng (Alex) Lu, held an experiment of 5 groups of beehives, four with different doses of imidacloprid, a type of neonic, and one hive without. They monitored the hives for 23 weeks to see if the bees would experience CCD. Lu said, “After 12 weeks of imidacloprid dosing, all the bees were alive. But after 23 weeks, 15 out of 16 of the imidacloprid-treated hives—94%—had died... The characteristics of the dead hives were consistent with CCD, said Lu; the hives were empty except for food stores, some pollen, and young bees, with few dead bees nearby... Strikingly, said Lu, it took only low levels of imidacloprid to cause hive collapse—less than what is typically used in crops or in areas where bees forage” The study shows that even small doses of neonics have a huge impact on bees, which can lead to CCD. All of the hive abandoned had experienced signs of CCD because of the neonicotinoids. Moreover, in an interview by Neal Conan with Dan Charles, NPR's food and agriculture correspondent, talked about how neonics had negatively affected bumblebees behavior. Charles stated, “there were some scientific studies that came out that indicated that it might actually change their behavior in subtle ways. So there was a study done with bumblebees, where the
Threat of Pesticide Pesticides also known as neonicotinoids has been used extremely often in the fields and has impacted bees. “Overall, 75 percent of all honey samples contained at least one neonicotinoid, said the study, led by Edward Mitchell of the University of Neuchatel in Switzerland. Of these contaminated samples, 30 percent contained a single neonicotinoid, 45 percent contained two or more, and 10 percent contained four or five”(Kerry Sheridan). The plants take and soak in the Neonicotinoids which is travels into their tissues and the bees would feed on the plant and take in the neonicotinoids. However, crops were the greatest contributors of neonicotinoids for bees but wild flowers were.
Velasquez-Manoff (2007) wrote that millions of dollars was designated into finding out a main cause of CCD and Israeli Acute Paralysis Virus was pointed out to be one of the largest components. This virus spreads easily from bee to bee, causing this to be one of the most popular viruses known to bees. Similar to humans, when bees catch a sickness, they become weak and are no longer able to pollinate the flowers regularly. When this sickness advances enough, they die. Edelbaum, Gantman, Lavi, Maori, Mozes-Koch, Peretz, Sela, and Tanne conclude that “an early survey of healthy and CCD-affected colonies in the U.S. found a significant correlation between CCD-affected colonies and Israeli acute paralysis virus (IAPV).”
Another problem is that they have no available water and what water is available is contaminated. Another reason could be because of the use of some many pesticides. The author of the Bulletin of Insectology writes: “When CCD first emerged in honeybee colonies in the mid 2000’s, N. ceranae was put forward as a possible cause.
Today’s honeybee population; is rapidly decreasing and disappearing by the bulk because of habitat loss, pesticide exposure and other parasites. This rapid
