Insecticides essays

Insecticides essays 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). Chlorinated hydrocarbon insecticides, also know as "organic chlorines", contain chlorine atoms (World Book 1999). Common members of this group are Acaralate, Acarol, Aldrin, BHC, Chlordance, Chlorobenzilate, DDT, dicofol, dieldrin, endosulfan, endrin, heptachlor, kepone, lindane, methoxychlor, mirex, perthen, TDE, and toxaphene (Hamm 1982). They're persistant because after being used once, they can still affect living things for several years. This is because they don't break down chemically so they're found in soil, animal and fish tissue, plants, and water (Hamm, 1982). These, and all persistant insecticides, are trying to be replaced and restricted because they kill bird, fish, and other animals (World Book, 1999). Organophospahte Insecticides contain phosphorus atom (World Book, 1999). Common members o...
