Phenomena of triptrophic interaction are well known in the agricultural area. Some specific volatiles is released from host plants after the infestation of pest insects, to attract parasitoids. Volatiles are formed during the biochemical process before released to open air. The phenomena of volatiles adsorption and desorption were investigated using spectroscopic methods. The model material was biosilica-nanocellulose which is porous and made by sol-gel processing and represented the wounded tissue plant in the tritrophic interaction. Some similar hydrocarbons from the previous study were adsorbed onto the surface and investigated. Some UV-visible and infrared spectra of adsorbed chemicals were recorded while the released gasses were captured and separated in the gas chromatography column. The result showed qualitatively molecular attachment into polar surfaces, and gas chromatography-mass spectroscopy indirectly determines the molecule desorbed from the solid interface and its pattern.
