Insect Growth Regulators (IGRs)

In recent years many of the conventional methods of insect control by broadspectrum synthetic chemicals have come under assault and scrutiny because of their undesirable effects on human health and the environment. As a consequence, new approaches have been tested and implemented. One of these approaches which has captured worldwide attention is the use of analogs and antagonists of insect growth regulators (IGR) such as juvenile hormones (JH), ecdysones, chitin synthesis inhibitors, and related compounds. It must be understood that compounds of this type are also chemicals, but because of their low toxicity to mammals, their selective toxicity toward insect species, and their safety to the environment they can assume a prominent role in the “integrated pest management” program.
