Behaviour desorption study of the essential oil of Cedrus atlantica in a porous clay versus insecticidal activity against Sitophilus granarius: explanation of the phenomenon by statistical studies

Abstract

Substances of natural origin and more particularly essential oils currently represent an alternative solution in the fight for the protection of stored foodstuffs. The way to use these essential oils and the storage conditions remain the main handicap in dealing with this subject. This article develops the use of porous supports as a medium for the study of the behavior of essential oils with respect to insecticidal activities. The process relates to the fixing and/or grafting of essential oils in porous clay media in a well-defined geometric form included in the storage methods. The study of transfers of the essential oil of Cedrus atlantica in a porous clay medium in the case of desorption was made by analytical and numerical models of diffusion process, to know the behavior of the oil and to determine some physical parameters (diffusivity Dz, activation energy Ea, evaporation rate F and constant of evaporation K) which explain the mechanisms involved and to try to exploit them in parallel with the insecticidal activities against of Sitophilus granarius the main cereal pest by statistical approaches such as: design of experiments and principal component analysis.

Essential Oils of Ocimum basilicum L. and Ocimum americanum L. from Djibouti: Chemical Composition, Antimicrobial and Cytotoxicity Evaluations

“…The global demand for essential oils has currently risen in several industrial sectors [1][2][3][4]. Essential oils are part of the extract of aromatic plants that are distributed in all countries of the world, where they are considered an imperative element of traditional medicine systems [5,6].…”

Assessment and Optimization of the Insecticidal Properties of γ-Al2O3 Nanoparticles Derived from Mentha pulegium By-Products to Xylosandrus crassiusculus (Carob Beetle)

“…Principal Component Analysis (PCA), a multivariate statistical technique [ 59 , 60 ], was utilized to investigate the relationship between the insecticidal properties of the synthesized nanoparticles and the mechanical attributes of the carob beetle panels affected by insects concerning the geographical origin of the strains under study. The research monitoring was carried out on the resulting matrices obtained during the optimization phase in the seven regions of Khenifra.…”

Correlation of the Diffusion Parameters and the Biological Activities in the Formulation of Pinus halepensis Essential Oil in Phosphogypsum Material

“…A specific volume of essential oil (EO) was combined with a measured amount of phosphogypsum powder (PG) at concentrations ranging from 10% to 50% (v/w) to ensure complete absorption of the oil by the powder. The resulting EO-PG formulations were then transferred to metal cylinders with diameters of 1 cm for subsequent experimental analysis [21].…”
