The ant population will be more likely to survive a drought.

|
|
The population of ants will be able to be sprayed with the insecticide and remain unaffected.
|
|
|
The grasshoppers will learn to feed in areas where no insecticides are being used.
|
|
|
The insects will use more energy to resist the insecticide which will cause a decline in their population.

Detailed explanation-1: -Genetics and intensive application of insecticides are responsible for the rapid development of resistance in many insects and mites. Selection by an insecticide allows some insects with resistance genes to survive and pass the resistance trait on to their offspring.
Detailed explanation-2: -When a pesticide is sprayed on a field most of the insects are killed because they are sensitive to the pesticide. A few of the insects survive because they have variations which made them resistant against the pesticide, such that the pesticide has no effect on these insects.
Detailed explanation-3: -Subsequent uses of the pesticide increase the proportion of less-susceptible individuals in the population. Through this process of selection, the population gradually develops resistance to the pesticide. Worldwide, more than 500 species of insects, mites, and spiders have developed some level of pesticide resistance.
