"As an insect grows it molts, growing a new exoskeleton under its old one and then shedding the old one to allow the new one to swell to a new size and harden. IGRs prevent an insect from reaching maturity by interfering with the molting process. This in turn curbs infestations because immature insects cannot reproduce. Because these IGRs work by interfering with an insect's molting process, they kill insects more slowly than traditional insecticides. Death typically occurs within … " - Chitin synthesis

Chitin synthesis

WebChitin is the second most abundant biological polymer after cellulose. It is widely distributed in arthropods, fungi and nematodes. Although the first benzoylphenylurea chitin synthesis inhibitor (diflubenzuron) was introduced to control various insect pests about three decades ago, the exact mechanism of action of this class of compounds has also not been resolved. WebThe chitin structure in native environments and cell walls of algae and fungi, for example, is much more complicated than the simplified models, which are determined using high-crystallinity and purified chitin materials. This is due to the complexity of chitin synthesis and the complex environments of chitin and other cell-wall components [12,24].
