The intensive use of broad-spectrum insecticides has caused among other undesirable effects, increase of the environmental hazards, negative effects on nontarget organism, and develops of resistance of several insect pests. For these reasons, efforts has been made during the last three decades to develop novel insecticides that act on selective biochemical sites present in specific insect groups. One of the results of this approach, which has captured worldwide attention, is the discovery of the latest class of insect growth regulators (IGRs), the ecdysone agonists or nonsteroidal ecdysteroid agonists, which affect the hormonal regulation of molting and developmental process in insects. Their narrow spectrum of activity, low ecotoxicological profile, and short persistence in the environment makes these compounds ideal for use against many economically important agronomic and forest pests. The insecticidal, ecotoxicological properties and mode of action of these important compounds are reviewed in this article.
