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 … WebChitin Synthesis Inhibitors (CSIs) As the name of these IGRs indicates, they inhibit chitin synthesis. Chitin is a major component of the insect body wall (cuticle), and it is present in the peritrophic membrane. 1291 Chitin is a linear homopolymer of the aminosugar, N-acetyl-D-glucosamine. high blood pressure allergy medication
