Insecticides
An insecticide is used to kill insects. There are many kinds of insecticides, but organic insecticides are the most commonly used (World Book, 1999). Organic insecticides are split into three different categories: Chlorinated hydrocarbon insecticides, organophosphate insecticides, and carbamate insecticides (World Book, 1999). In this paper, I'll explore how toxic each of these insecticides are, how they affect wildlife, humans, and the environment, and what we can do to help. Some insects, like white flies and mosquitoes, can carry deadly diseases that affect crops, animals and humans. Insects can cause about 5.5 billion dollars in crop and live stock losses every year. Some of the diseases they cause are Cattle Fever and Sheep Scab. The insecticides are used to kill insects and protect livestock (World Book, 1999). Insecticides can also be used on flea treatments for cats, dogs, and other animals (Ackerman, 1996). Organic Insecticides are the most commonly and widely used insecticides. They are synthetic substances made from carbon, hydrocarbon insecticies, organophosphate insecticides (World Book 1999).
Organophospahte Insecticides contain phosphorus atom (World Book, 1999). Common members of this group are Abate, azinphosethyl, azinphosmethyl, Bidrin, bromophos, bromophosethyl, carbophenothion, and chlorfenvinphos (Hamm, 1982). They are used on food because they don't leave harmful deposits behind (World Book, 1999). This is because the breakdown rapidly into harmless components. They also break down in the presence of water. They have less environmental danger than chlorinateed hydrocarbons which is why they've almost replaced them for side scale usage (Hamm 1982). However, they are poisoness to people. One type of organophosphate, paratheion, is used to kill mites and aphids on fruit trees and vegetables. Another kind, malathion, are less dangerous to apply, so they're widely used by farmers ( World Book, 1999). 1. Ackerman, Lowell: http://www.pet- zone.com/petzone/health/dog/10043.htm. I found that this topic was kind of hard to research. At first, I thougght it would be easy, but it wasn't. I found most of my information in books and encyclopedias because the internet and periodicals barely had anything I could use.
