昆虫生长调节剂(IGRs)由于具有和常规杀虫剂不同的独特作用方式而受到人们的重视.1972年,Schafer和Wilder将IGR分成昆虫发育抑制剂(IDI)和蜕皮抑制剂(MI)两类.前者包括下面讨论的昆虫激素类似化合物,后者则包括几丁质合成抑制剂.昆虫激素在昆虫发育过程中起重要作用,其中已知的有脑激素、蜕皮激素和保幼激素.脑激素刺激前胸腺释放出蜕皮激素,蜕皮激素(α-蜕皮激素)转化为20-羟基蜕皮激素(β-蜕皮激素),刺激生成新的表皮,从而诱导蜕皮.
Insect growth regulators (IGRs) have received considerable attention due to their unique and distinct role as conventional insecticides. In 1972, Schafer and Wilder classified IGRs as two types of insect development inhibitors (IDIs) and molting inhibitors (MIs) The former includes the insect hormone analogs discussed below, while the latter includes inhibitors of chitin synthesis.Hormone hormones play an important role in insect development, among which are known brain hormones, ecdysone and juvenile hormones Stimulation of the anterior thymus releases ecdysone, which converts ecdysone (alpha-ecdysone) to 20-hydroxyecdysone (beta-ecdysone), stimulating the production of new epidermis and inducing ecdysis.
