What role do insect growth regulators play in pest management?

• A. They enhance the growth of beneficial insects
• B. They disrupt normal insect development for control
• C. They act as a repellant to all insects
• D. They are used to increase pesticide effectiveness

Answer: (B)

Insect growth regulators (IGRs) play a crucial role in pest management by disrupting the normal development and growth processes of insects. These substances mimic hormones that are essential for insect growth and development, affecting their ability to molt, mature, or reproduce. By interfering with these natural processes, IGRs prevent pest populations from establishing, significantly reducing their numbers. The use of IGRs is beneficial because they target specific developmental stages in pests, often with minimal impact on non-target species, including beneficial insects, which helps in maintaining ecological balance. This targeted action makes IGRs an effective tool in an integrated pest management strategy, allowing for effective control of insect populations while minimizing harm to the environment and beneficial organisms.
