What is the purpose of using insect growth regulators (IGRs)?

Using insect growth regulators (IGRs) is primarily aimed at disrupting the life cycle of pests. IGRs are synthetic compounds that mimic the hormones in insects responsible for growth and development. When IGRs are introduced into an environment, they interfere with the normal processes of molting and maturation of insects, preventing them from reaching reproductive maturity. This disruption effectively reduces the population of pests over time, as they are unable to reproduce and complete their life cycles.

This method of pest control is particularly valuable because it can target specific life stages of insects and often has a lower impact on beneficial insects and the environment compared to traditional insecticides. IGRs provide a strategic approach to pest management, contributing to integrated pest management (IPM) strategies that help maintain ecological balance while managing pest populations effectively.
