Pest Control Technician Practice Exam

Insect Growth Regulators (IGRs) are specifically designed to disrupt the normal development of insects. The correct description of their operation is related to their ability to interfere with the formation of reproductive organs. IGRs work by mimicking hormones that are essential for the processes involved in insect growth and development, particularly across various life stages. When an insect is exposed to an IGR, it can prevent the insect from maturing into an adult or disrupt its ability to reproduce effectively, thus influencing the population dynamics of the pest. This targeted approach minimizes the impact on non-target species and the environment, making IGRs a valuable tool in integrated pest management strategies. By focusing on the developmental stages and reproductive capabilities of pests, IGRs can significantly reduce pest populations over time without relying on toxic substances that kill adult insects on contact.
