Widespread use of insecticides can lead to the evolution of insecticide resistance.
In any population of insects there will be genetic variation ie individual insects are not identical; just like humans there are all different. Some individual insects will be more resistant to an insecticide than others.
When an insecticide is used the individuals which are resistant will have a better chance of surviving. They will then pass on their resistance genes to their offspring, which will in turn have a better chance of surviving. In this way the resistance genes will spread through the population.
This is an example of natural selection in action.

What is the central force driving evolution?

What are two characteristics biologists look for in new crops?
Fertilizers and Insecticides.
Is limited resources discourage the evolution of species true about evolution?
No. It is merely one of many parameters that influence the direction of evolution, and can actually be a driving force in evolution. For example, the rise of warm-blooded mammals as a result of colder climate (a clear period of limited food resources) caused by climatic or astronomical phenomena, like the impact of a meteor.
Humans have promoted the evolution of insects that are resistant to insecticides by?
trying to control pests with chemical
Explain for the loss of effectivenss of the insecticides?
It is evolution causing bugs to become resistant. Longer explanation below: Bugs that were immune to insecticides originally were rare. After the insecticides were used, only the immune bugs survived. All new bugs that were born were the children of those with immunity, and so they kept that trait.
Humans have inadvertently promoted the evolution of insects that are resistant to insecticides by?
Insects became resistant because the insecticides were used on the continuously. Most insects will die at first, but there will be some that have the right genetics to resist that insecticide. When that happens the insect will the favorable gene reproduces and creates more insects that are resistant. Humans promoted this evolution by using the same insecticide on the insects.
