Schemical Detection by GC-MS Technology of Asclepias Curassavica and the Effect of Chloroform Extract on the Stages of Tribolium Castaneum (Coleoptera Tenebrionidae)

Abstract

The active compounds were detected using gas chromatography-mass spectrometry GC-MS of Turkish oleander plant Asclepias curassavica and their effect on the life stages of the red flour beetle Tribolium castaneum. The results showed that Turkish oleander contains 19 active compounds, including Phytol and Hexadecane, which It has an insecticide effect and many therapeutic properties. The effect of chloroform extract of oleander leaves was tested using direct and indirect spraying methods on the percentage of death of red flour beetle phases in concentrations (10%, 20%, and 30%). The study also showed the superiority of the direct method on The indirect method where the killing rate reached 84.8% and 81.9%, respectively, for the stages of the insect, and the concentration of 30% gave the highest killing rate of 94.4%. The results also showed that the most affected by the chloroform extract is the adult insect.
