Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	True
B	False
C	Either A or B
D	None of the above

Explanation:

Detailed explanation-1: -Worldwide, more than 500 species of insects and related arthropods are resistant to insecticides. To search a registry of resistant insect pests, log onto the Arthropod Pesticide Resistance Database.

Detailed explanation-2: -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-3: -Resistance is defined as a change in the sensitivity of a pest population to a pesticide, resulting in the failure of a correct application of the pesticide to control the pest. Resistance can develop when the same pesticide or similar ones with the same mode of action are used over and over again.
