Pyriproxyfen is a pyridine-based insecticide that functions as a juvenile hormone analog, disrupting the growth and development of insects. It is effective against a variety of pests, including whiteflies, fleas, and mosquitoes, by inhibiting the maturation of larvae into reproductive adults. Introduced in 1996, it has been widely used in agriculture to protect crops and in public health initiatives to control disease vectors.
