What are the long time affects?

Resistance means that the pesticide doesn't work and the long term effect is that whatever you are trying to protect from those pests will be destroyed by them because the pesticide doesn't kill them. Say for example, you buy a pesticide to protect your veggies in your yard from being eaten by bugs, you spray it, but the bugs won't die, they eat your tomatoes and zuccinis---and you pollute the air with the pesticide.

Pesticides are developed to kill pests.
There is a specific mechanism by which they kill the pests.
Several types of bio-molecules of the pest are involved in this interaction.
Now, when there is change in one or more bio-molecules of the pest, this interaction does not take place.
And hence the pest becomes resistant to the pesticide.
The pesticides are toxic chemicals developed by man.
Some of them are not degraded easily in nature.
They keep on accumulating in the bodies of plants, pests, birds, and animals.
These toxic chemicals cause a variety of physiological diseases such as allergy, cancer, diabetes, impotency etc.
Somehow, one must control the pests to get good agricultural produce.
So the scientists who believe in the use of toxic chemical pesticides, develop further toxic material (once they find that the pests are resistant to previous version).
This increases the hazards.
One good example is a project run on several hundred acres in Bangladesh on use of pesticides in paddy.
They have shown that even after reduction in toxic chemical pesticides by 90% and 99% there was no significant decrease in the yield.
This means there are alternate ways.
Are we geared up?

Pesticide resistance is the ability of a pest population, such as insects, fungi, weeds or rodents, to evolve a tolerance to a pesticide that it was previously susceptible to.

Resistance to pesticides...Duh!
The long term "E"ffects for the insects would be...LIFE.

It means that some insects have built up a resistance to bug killer sprays. It is not good because insects carry disease and we need a way to kill them. Bedbugs, cockroaches and lice are particularly bad insects.

New and stronger pesticides would need to be developed and used....impact on the environment??????
