What is the function of insect growth regulators (IGRs)?

• A. To attract more pests
• B. To interrupt the life cycle of pests
• C. To eliminate adult pests only
• D. To stimulate rapid growth of pest populations

Answer: (B)

The function of insect growth regulators (IGRs) is to interrupt the life cycle of pests. IGRs work by mimicking hormones in insects, which helps to disrupt their normal developmental processes. This interruption can prevent larvae from maturing into adults, inhibit molting, or prevent successful reproduction. Because IGRs target specific developmental stages of insects, they are particularly effective at managing pest populations over time by reducing their ability to reproduce and grow into mature, reproductive adults. This method of pest control is advantageous because it can reduce pest populations without the immediate lethal effects that many traditional insecticides have on adult insects. As a result, using IGRs can lead to a more sustainable approach to pest management, lowering the chances of resistance developing in pest populations, since these products work at the developmental stage rather than killing adults outright.
