Abstract

A delivery system of insecticides induces active ingredient having desirable for pest control and nanotechnology may be improve of pesticide efficiency. Chlropyrofos as an organophosphate insecticide is used to control many different type of agricultural pest such as termites, mosquitoes, cockroaches. Termites, one of the important pests, cause a lot of damages to many field of agricultutre and in the south of Iran, subterranean termite, is popularly damages many products. In this research, chlropyrofos was loaded onto poly(ethylene glycol) and chitosan decorated nanoparticles (silver/PEG/Cts NPs) and evaluated its insecticidal (termiticide) study. Silver nitrate was used as the silver source and chitosan and PEG were used as the polymeric supporter and stabilizer and chlropyrofos as insecticide. The developed Ag/PEG/Cts NPs-chlropyrofos were then characterized by a UV-VIS spectrophotometer, Fourier transform infrared, transmission electron microscope, confirmed the formation of spherical nanoparticles with the size of 15-25 nm. The insecticidal activity of nanoparticle was tested in vitro against termite (Microcerotermes gabrielis W. (Isoptera: Termitidae)). The result showed the effectiveness of the target nanoparticles after 48 h at 50 ppm on the insects.
