Description and Uses

Methoprene is the common name for a racemic mixture of two enantiomers (R and S in a ratio of 1:1). The activity of the compound as a juvenile hormone (JH) mimic is restricted to the S enantiomer. Methoprene was the first insect growth regulator approved in the 1970s by the US Environmental Protection Agency after extensive studies showing low toxicity to vertebrates and rapid natural chemical degradation in the environment and through organism metabolism. Nowadays, it is one of the most widely used and successful insect growth regulators. Different products containing methoprene (e.g., pesticides, veterinary drugs) are commercially available in different forms (emulsifiable concentrates, granules, pellets, briquettes, aerosols, or sustained-release formulations). Some of these are applied to water for mosquito control whereas others are sprayed in areas where foods are stored to prevent insect infestations. Methoprene may be used in combination with other active insecticides to optimize pest control.
