In mosquitoes, methoprene was reported to interrupt the lysis and re-absorption of old endocuticle, thus halted the synthesis and deposition of new, complex procuticle by the epidermal cells. Cocke, et al. (1979) concluded that the tissues examined were suggestive of possible

WebFipronil is a broad-spectrum insecticide that belongs to the phenylpyrazole chemical family. Fipronil disrupts the insect central nervous system by blocking the ligand-gated ion channel of the GABA A receptor and glutamate-gated chloride (GluCl) channels. This causes hyperexcitation of contaminated insects' nerves and muscles. WebGuideline.

WebMethoprene. Methoprene is an insect growth regulator (IGR). IGRs such as methoprene are used to disrupt and impede the life cycle of insects in the egg and larvae stage of development. The idea behind IGR use is that if a given insect cannot reach adulthood, it cannot reproduce.
