Now the entire population is resistant. Here is an example of how to make a population of insects pesticide resistant (micro-organisms respond similarly to antibiotics): Assumption: Insect Population I has a 99% mortality when exposed to Pesticide P Stage 1: 100,000 Population I insects are treated with Pesticide P Stage 2: Pesticide P treatment kills 99% of Population P Stage 3: 1,000 insects survive and reproduce Stage 4: Population R is 100% resistant to Pesticide P
