I believe you just answered it yourself. they development an immunity to insecticides the more they are exposed to it.
<span>The
answer is allelic frequency. This is also the fraction
of a particular allele of a gene in the population. Allelic
frequency in a population of diploid individuals is calculated using the Hardy Weinberg equation
of p2 + 2pq + q2 = 1. Allelic frequency of all the alleles of the genes must add up to 1 (one).</span>

Herbivores are those animals that feed only on plants. Herbivores are food for carnivores, which feed on other animals. If a particular herbivore is over hunted by man, the particular carnivore that feed on that over hunted herbivore will be affected, because its source of food has been wiped out. Thus, it will have one less choice when it comes to food and it will have to concentrate on other type of herbivore as source of food. Thus, other herbivores in that particular ecosystem will be affected too.
