Recommended: Pesticides and their harmful effects
In this investigation I am going to look into how various different types of pesticides affect the Honey Bees, and if they are the cause of the decline in honey bees.
A single honeybee visits hundreds, sometimes thousands, of flowers a day in search of nectar and pollen. Then it must find its way back to the hive, navigating distances up to five miles (eight kilometres). \previous studies have shown certain types of pesticides affect a bee's learning and memory
A pesticide is any substance used to kill or control certain forms of plant or animal life that are considered to be “pests”. Pesticides include herbicides for destroying weeds and other unwanted plants, insecticides for controlling a wide variety of insects, like Bees, fungicides used to prevent the growth of molds and mildew, disinfectants for preventing the

With pesticide consumption increasing several folds during the last four decades, the side effects are also increasing and one of which is the toxicity to honey bees. According to a study in the UK, pesticides damage the ability of bees to gather food and are also killing them in the process. Since bees are the most important pollinators of crops, the use of pesticides can considerably reduce the yield of cross pollinated crops. In addition, contamination of bee products and loss in production of honey are the other effects caused by pesticides on bees.
Unfortunately, many pesticides are harmful to bee population. There are some pesticides that kill the bees directly. This happens when bees are on the flowers at the time of application of the insecticide, and the bees die instantly. Some other types of pesticides, allow the bees to return home and then they die. Such types are easy to identify than the first ones. There are certain pesticides that do not have any effect on the adult honey bees, but cause damage to young, immature bees.
What is a pesticide?A pesticide is a chemical substance used to kill pests, especially insects. A pesticide is also refered to as a biocide. Most pesticides are applied in spray form but occasionaly you will see pesticides that are in powder or pellet form. Pesticides are used on a variety of things, anything from crops like corn, barley, and wheat, to plants like petunias, marigolds, and rhodadendrons, which are usually found in small gardens greenhouses, and even in your backyard.
Bees are known throughout the world as dangerous threats and pests to humanity. Bees when left alone are very important to the growth of all the worlds’ crops and plants; they affect the growth of all the crops plant just as much as butterflies and other pollinators. Humans rely on bees for honey and pollination of plants, but what most agricultural workers don’t know is that they are working on the extinction of the common honey bee by doing simple things in their every day jobs on the farm. With the use of pesticides and other harmful things such as an unnatural diet and cramped living spaces, bees can go extinct and without a large group of pollinators our plants ...
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.
To most, the honeybee can be an annoying insect that has a powerful sting. Yet, the honeybee is so much more than just another insect. The honeybee is arguably the most vital component in the development of our food crops. With roughly 90 percent of our food crops dependent on the pollination of our honeybees, our food system, agricultural development, and diet rest on the work and well being of these buzzing insects. Unfortunately, since 2006 there has been a major decline in the population of honeybees, and has gotten progressively worse because of colony collapse disorder. The first reported increase of CCD was documented in November 2006 in Florida. By February 2007, several states began reporting major losses associated with CCD, ranging from 30% to 90%. A little over a half decade later in 2012 the attention paid towards CCD has grown substantially with more research being done as CCD continues to get worse. The main culprit for CCD, as research has suggested, is the use of pesticides on our food crops. With major corporations such as Bayer making millions and millions of dollars in profit each year in the distribution of pesticides, it is no wonder that nothing is being done to stop this practice despite evidence linking the use of pesticides and the drastic deterioration of the health of honeybees. With the continuation of the use of deadly pesticides and the vital role bees play in the pollination and development of our food crops, both the environment and our economy will be effected directly and face the potential for catastrophic results.
The best action the public can take to improve honey bee survival is not to use pesticides indiscriminately. In particular, the public should avoid applying pesticides during mid-day hours, when honey bees are most likely to be out foraging for nectar and pollen on flowering plants. In addition, the public can plant pollinator-friendly plants—plants that are good sources of nectar and pollen such as red clover, foxglove, bee balm, joe-pye weed, and other native plants.

The worldwide eradication of honey bees may not be too far away. The reasons the honey bees are dying are linked to a number of things. The most common causes are linked to industrial agriculture, parasites/pathogens, and climate change, according to the article entitled “The Bees in Decline” on GreenPeace’s website, SOS-bees.org. However, bee-killing pesticides pose the highest risk to the pollinators (the Bees). Honey bees are not the only form of pollinators.
A question commonly associated with the word insecticides is, what are they? Well I have the answer, insecticides are chemicals that are used to eliminate insects. In the agricultural industry, insecticides are classified into different categories,and the most used is carcinogenic. A carcinogenic insecticide is a substance or agent producing or causing cancer. This is just one of the reason that I believe there are more cons then pros when dealing with a insecticide.. When I was a kid , I can remember my parents taking me and my brother an apple orchard and picking apples. I couldn't wait to eat them until I got home, but we couldn't eat an apple because of what insecticides could be on the apple
...ortation of plants, fruits, vegetables, and animals. Indiscriminate pesticide use kills the good with the bad. Long term and wide spread pesticide use poisons underground water sources, which, in turn, poison plants, animals, and humans. And, finally, by our uninformed actions, new super races of pests continue to evolve and create even greater dangers than the original.
Pesticides are used daily throughout all types of places. In rural areas, farmers are applying pesticides on their crops to protect them from the devastation that some insects can have. In urban areas families are using pesticides to protect their houses and their children from pests. There are many different sections of pesticides. Fungicides kill fungus, herbicides kill plants, rodenticide kill rodents, larvicides kill larvae, and bactericides kill bacteria. When people use pesticides, they feel as though their houses and children are protected. Many people don’t see the down fall of using such harsh chemicals. Exposure to harsh chemicals can send your body in a downward spiral.

As time has progressed, there has always been an overarching need for high amounts of crop production throughout the world. With the rapid rate of population growth, the need for crops and other sources of nutrients is only increasing. In order to meet these high demands and increase yields, farmers and other agriculturalists have started implementing the use of pesticides. These chemical mixtures are being used in order to prevent, destroy, repel or mitigate any pests from destroying growing crops. However, using pesticides on crops can create massive amounts of pollution, negatively affect an individual’s health, and can spark biodiversity loss within an ecosystem. According to Michael C.R. Alavanja, “Over 1 billion pounds of pesticides are used within the United States (US) each year and approximately 5.6 billion pounds are used worldwide”. With all this in mind, it is clear that pesticides should not be made available to farmers and agriculturalists, and should
There are 2.5 billion pounds of pesticides being applied to agricultural products each year in the United States. This is ten times more than was applied forty years ago. It is still unknown as to what type of exact effects these chemicals may have on individuals. Some farmers that have been using pesticides in their fields and developed leukemia are finding that the cause of their disease is from inhaling pesticides. These chemicals are still in use today and most of them have never been tested for the short or long-term effects that they may have on humans.
...not detrimental, and it’s always possible for people to build up a good relationship with bees. It is quite challenging, but the bees have a job to do and threatening their quality of life will consequentially threaten everyone’s. Another possible choice is to join a local beekeepers' association to become better informed about the care and keeping of honeybees and other steps you can take to stimulate colony growth and combat CCD. Scientists also have been working overtime in an attempt to determine the cause of CCD. They have linked CCD to many factors including the Varroa mite and Nosema. Recently, a Harvard biologist published a study directly linking the pesticide imidacloprid. Still the consensus is that multiple factors are to blame which is why many scientists are looking at ways to improve a honey bee’s health and immune system as the potential solution.
Pesticide is a chemical used to prevent, wipe out and control the pest problem in agriculture. The use of pesticides have become a common practice around the world, and used almost everywhere, such as agricultural fields, homes, park and school, and so on. Most pesticides are insecticides, herbicides and fungicides that have distinct purposes. Insecticides are used to control insects; herbicides are used to destroy plants; fungicides are used to prevent molds and mildews. Most commonly pesticides contain highly toxic chemical such as Acid copper chromate (ACC), Acephate and Chlorpyrifos, and so on. One of example of insecticides, Chlorpyrifos, sprays widely on a variety of food and golf courses in order to control pests in a cornfield. However, “Chlorpyrifos can cause cholinesterase inhibition in humans; that is, it can over stimulate the nervous system causing nausea, dizziness, confusion, and at very high exposures (e.g., accidents or major spills), respiratory paralysis and death.” (EPA GOV) In the market has thousands of products are similar as Chlorpyrifos.
