Meaning and Definition
A synthetic chemical compound used as an insect growth regulator.
Methoprene is a juvenile hormone analog that interferes with the normal development and maturation of insects, particularly in their larval stages. It is widely used as an insecticide in pest control for mosquitoes, fleas, and various stored product pests, as it prevents them from reaching reproductive adulthood. While not immediately lethal, it offers long-term control by breaking the reproductive cycle.

It mimics the juvenile hormone in insects. When larvae are exposed to it, they cannot moult into normal, reproductive adults, effectively sterilising the population over time.
No, methoprene has no effect on adult insects. It only affects the larval stages. It is often combined with an adulticide for immediate knockdown and long-term control.
It is an active ingredient in many flea sprays, foggers, and pet collars, mosquito larvicides (e.g., in standing water), and products used to protect stored grains and tobacco from pests.
