Synthesis and Characterization of Some Chitosan-Quinoline Nanocomposites as Potential Insecticidal Agents

Abstract

The quinoline-acid hydrazide derivative was synthesized and transformed into a variety of interesting N-heterocycles like pyridazinone, oxadiazole, triazolopyridazine, and triazole derivatives. These N-heterocycles interacted with chitosan nanoparticles to produce different chitosan-heterocyclic nanocomposites. The nanocomposites obtained were characterized using Transmission electron microscopy, X-ray diffraction, and Fourier-transform infrared techniques and exhibited a somewhat narrow size distribution with an average particle size of 10-53 nm. The insecticidal activity for some of the synthesized N-heterocycles and their nanocomposites obtained were screened against Mythimna separata and Nilaparvata lugens. The obtained chitosan-N-heterocycles nanocomposites enhanced the insecticidal activity.
