Abstract

This search presents the effect of some ecological factors such as (ultraviolet –B radiation , temperature , salinity )  on stomatal index and stomatal frequency and phenolic compounds after exposure to Aloe vera L. UV-B radiation , temperature and salinity . Ultraviolet – B radiation is one of the important abiotic factors that can stimulate the production of secondary metabolites, including phenolic compounds. Aloe vera (Asphodelaceae) is a medicinal plant used in Iraq for treating sunburn, wounds, and heartburn. The flour beetle: Tribolium castaneum is one of the inset causes of loss storage food yield in the world. The study aims  the effect of some ecological factors such as (ultraviolet –B radiation , temperature , salinity )  on stomatal index and stomatal frequency and phenolic compounds after exposure to Aloe vera L. UV-B radiation , temperature and salinity and  investigate the insecticidal and repellency effect of leaf gel for Aloe vera to estimate the percentage of the insecticidal effect for concentrations 25, 50, 75, and 100 % of alcoholic extract within seven days on adult insects. The gel in leaf exposure to UV-B radiation contained a higher diversity of phenolic compounds and flavonoids. This search showed a high percent kill for an adult with 100% of the alcoholic extract compared with control and an excellent effect of Aloe vera gel at a concentration of 50 %  for a repellency effect with a value of 10.842%. Phenolic compounds showed after exposure to UV as : (dioxyflavone ,kampferol, catechuic acid, flavonol glucuronic acid, gabardine isoflavone, isoquercitrin, p-coumaric acid, hispaglabridine ) with a high percentage in the gel after exposure to UV-B compared by control.
