how do insecticides kill insects??

Question

plz answer soon.... i have a project to work on about this.

Answer 1

Depends on the type of pesticide.

Many of the big name pesticides, such as parathion and malathion, are organophosphorus cholinesterase inhibitors. They block the action of acetylcholine in the body of the insect.

Carbamate insecticides, such as Aldicarb, Carbofuran, and Carbaryl, are also cholinesterase inhibitors, though not quite as powerful as the organophosphorus compounds.

Then there are the organochlorine pesticides -- Aldrin, Dieldrin, DDT, Chlordane, etc -- are neurotoxins. They also stop nerve function in insects, but by a different mechanism.

If you can find it in a library, check out the referenced text. Lots of good info there. I own a copy of the Second Edition, copyrighted 1999.

Answer 2

Different kinds of insecticides kill in different ways. I would suggest that you actually do some research on specific insecticides and see what you can find. I'd probably suggest picking 2-4 different compounds and doing a google search on them. You should be able to find out how each one works.

Answer 3

Some attack their nervous system. The kind that cause Gopal India disaster.

Some poison them in other ways.

Some suffocate them.

There are some that make them sterile, this is use to sterilise male this works because lots of them mate once and die. So they mate and die, female live out the life but do not produce off springs, so they cannot propagate.

Answer 4

The same way they can kill you or I. They should be refered to as biocides as Rachel Carson once suggested.
