The Effects Of Pesticides On The Ecosystem Of Agricultural Organisms

Carson clarifies that “the sprays, dust, and aerosols are now applied almost universally to farms, gardens, forests, and homes-nonselective chemicals that have the power to kill every insect, the “good” and the “bad”.” In contemporary world today many people use these mankind chemicals without understanding the effects of nature. For example, the reproduction of bees are dropping traumatically because of the pesticides effects on the insects. According to CNN “How Pesticides are killing the bees “Recent data published in science, Nature and other un journals show that bees are dying from some pesticides that are found in our food supply.” The damaged the chemicals are doing to the bees have worries many scientists. The New York Times wrote, pesticide linked to honeybee deaths, “a group of pesticide believed to contribute to mass deaths of honeybees.” Another example of the harmful chemicals affecting the good insects are by destroying favorable insects such as lady bugs and butterflies, which are another great alternative way to pollinate flower. These beneficial insects are very important for human wellbeing; therefore, we should minimize the use of

Insecticides, fungicides, pesticides, and herbicides were the real cause for the bee population decline. The harmful chemicals that were sprayed

The bees never seem to catch a break which is putting the bees under “stress” which is a factor. Furthermore, when they are pollinating all these different plants some are not nutritious as others, for example cucumbers aren’t as healthy as some of the other plants but there is still a demand for them, so the bees still have to work and eventually become unhealthy if they aren’t getting the right nutrients. Another factor is pesticides, which has many different points of view but overall it has come to decided it is not the pesticides themselves that are killing masses of bees but it is lowering their immune system and making it easier for them to get sick, for example with the common parasite Nosema. Nosema is a parasite in the digestive track of the honey bee that attacks the entire hive and can eventually wipe out the whole hive. The effects of the pesticides are ultimately never letting the hives reach their maximum potential, which in the end could render the hives weak and lethargic. There are so many pesticides out there it is hard to tell exactly what component in the pesticide is hurting the bees. It is recently found that the inert ingredients used often to boost the effectiveness of the pesticide are actually more harmful than the actual toxic ingredients

Recently I read an article in the Hill Country Observer titled “Hives of Controversy” by Tracy Frisch (http://www.hillcountryobserver.com/2015news/Sept2015bees1.htm). The article talks about colony collapse disorder and the causes. The tests that have been done and continue to proceed mention that the insecticide neonicotinoids can be a major cause for the loss of bees. As with most if not all chemical insecticides they don't readily break

The bees are dying because of humans. Global warming, habitat destruction, pesticides, and air pollution are just some of the ways that humans are actively destroying the global bee population. The insecticide neonicotinoids are the most widely used, and also one of the most hurtful. Neonicotinoids can affect the bees’ ability to navigate back to their hive, and also can lead to a decline in queen bees. The insecticides weaken the bees’ immune system which allows them to be much more susceptible to getting sick, and dying. However, honey colony collapse Disorder is not exclusively caused by neonicotinoids, viral pathogens and parasite mites are also fatal to the bee population. “Wild bee habitat shrinks every year as industrial agribusiness

The effects of these pesticides are not killing the bees instantaneously but impairing their behavior and development. However, some pesticides are very lethal since the honey bees do not even go back to their hives and most of them die after ingesting small amounts of these chemicals from plants that have been sprayed with them. These pesticides clearly have a huge role to play in CCD, given that bee farmers in organic gardens have not reported this phenomenon. According to Timbrell (2002), the pesticides reduce the immunity of bees and are therefore susceptible to literally all kinds of pathogens. A dissection of the dead

Goulson shows a battle in whether pesticides , which are regarded as the materials that can harm crop pollinator should be forbidden.According to his research ,the chemicals in the pesticides can spread widely through pollinators , and little of the toxin may lead to the death of the bees. What's more ,if the exposure of the chemical to very low levels of neonicotinoids that are not sufficient to kill the bees but can influence the abilities and the behaviors .There are also some other researches but they are not convincing because of some obvious shortcomings.On the other hand , neonicotinoids can provide economic benefits and those are difficult to substitute. As a result, it is still a controversy should those pesticides can be

Although there have been improvements in the safety of fungicides, many still contain potentially dangerous compounds. Although commercial mercury has been replaced in fungicides, "the possibility of exposure to environmental sources of organic methylmercury still exists," which can negatively impact upon human health, such as when fish that have accumulated the toxin within their body are consumed (Hasan 2010: 358). Because fungicides are often used in combinations with other chemicals, the toxicity of the fungicide may be unexpectedly high (Hasan 2010: 358). For example, "recommended field application rates of Propiconazole are considered too low to kill a substantial number of bees, but when mixed with

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.

In the last century, the domestic honey bee population has declined by roughly 50 percent, and researchers have been grappled with the understanding what is exactly is causing the decline in the bee population. The main reasons for global bee decline are linked to industrial agriculture, parasites, pathogens and climate change. Scientists now believe at least some of these pesticides play a major role in Colony Collapse Disorder (CCD), the ongoing demise of honeybee colonies. There used to be “6 million honey bee colonies in the U.S. 60 years ago, now there are just 2.5 million. ”(Here

Being used worldwide, neonicontinoids which have a similar chemical structure/properties as nicotine have been used as an insecticide that attacks insect’s nervous systems for many years now. Being infused within the seed of the crop, bees can be in direct contact with the chemical from the pollen of the plant, “…neonicotinoids, or neonics, a nicotine-based pesticide that coats seeds and infuses all parts of a crop as it matures, are "a key factor in the decline of bees” (“Save the bees, save ourselves”). Experts statistically noticed that one hundred percent of corn seeds and sixty percent of soybean seeds in Ontario are treated with this chemical (“Save the bees, save ourselves”). Presence of these toxins in a bee’s system lead to weakness and eventual death themselves, or play a role in multiple disruptions to their bodies. With the chemical in their body the bee’s health begins to deteriorate as scientifically proven, “Exposure to thiamethoxam appears to impair bees’ homing ability, with consequences for colony survival” (“Save the bees, save ourselves”). Neonicotinoids amongst other chemicals have been linked to causing problems in the bee’s homing capabilities as well as introducing the possibility of the deformed wing virus. A neuroethologist at Newcastle University, discovered that the neonic-tained nectar possesses seemingly addictive

What these studies have not observed is the distinct differences between the specific neonicotinoids used, so the following sections will discuss what has been found and what we still need to understand before finalizing a decision on the reason behind honeybee colony death. By understanding these differences, a qualitative analysis may be created for neonicotinoids and agricultural sectors across the globe can use safer alternatives for their

As scientists and beekeepers keep on looking into the situation that they are all facing, one conclusion is definite, pesticides do have a lethal effect on the bees. Some symptoms that would lead to a bee’s death would be the weakened immune system, disrupted digestion, and the result of the brain failing. In Science Magazine, an article was written about oh the European countries have been effected by the decrease of bees, “Confused honey bees huddled trembling outside

Although insecticides aren’t sprayed directly to get rid of bees, the plants that bees have to pollinate are more likely farm crops instead of wild flowers found in their natural habitats. Some of the problems that chemicals present include reduced physical capabilities, a gradual decline in function, and loss of a queen bee. Because bees were being treated for the chemicals, their natural defense systems were impaired. Bees that were sick or infected stayed in the hive with the colony for longer periods of time. When the hive got too tainted, the queen would leave and the bees would have no eggs for future bees. The colony would either have to find a new queen or wait for an eventual end of the

In the past few week some beekeepers are reporting death of bees. This is occurring in southeastern United States where there are reports of the bees dying. The beekeepers are saying millions of their bees are dying because of the spraying of an insecticide meant to control the outbreak of the Zika virus. The Zika virus is spread by mosquitos. This spray used to kill the Zika infected mosquitos is a neurotoxin and it is also toxic to bees. Bees are important in pollination. This insecticide is being sprayed from the sky by government officials. It is meant to control the spread of the Zika virus.
