WebThe biosynthesis of chitin from the aminosugar is catalyzed by the enzyme “chitin synthase”. 130 ’ 321 CSIs inhibit the action of chitin synthase or interfere with insect … 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 …
