Explanation:
Detailed explanation-1: -Worldwide, more than 600 species of pests have developed some level of pesticide resistance. If resistance to a particular pesticide or “family” of pesticides evolves, these products can no longer be effectively used thereby reducing the options available for pest management.
Detailed explanation-2: -A classic example is the house fly. Populations of this insect that became resistant to DDT in the 1950s, also exhibited resistance, with no previous exposure, to pyrethroid insecticides used decades later. DDT and pyrethroids have the same MOA. This phenomenon is known as cross-resistance.
