Effect Study Of Foliar Crude Essential Oils Of Colocynthis Vulgaris (l.) Schrad (cucurbitaceae) On Cholinesterase Activity Of The Imagos Of Schistocerca Gregaria (forskål, 1775)

The present work focuses on the study of the effect of toxicity on cholinesterase activity and some physiological parameters in males and females of Schistocerca gregaria bred in the laboratory and exposed to crude essential oils of the leaves of Colocynthis vulgaris. The manifestations of general intolerance at this extract appear around 30 to 60 minutes after exposure, cholinesterase activity shows a decrease compared with the witnesses, she is 8.08 ± 2.65 nmol / min / ml in males and 16.34 ± 1.15 nmol / min / ml in females of Schistocerca gregaria treated by the extract essential oils from C. vulgaris. For lots of individuals treated, the rate of protein reveals a difference between females and males. Increases in males to reach 46.11 ± 16.17 mg / ml, whereas it is 35 ± 13.22 mg / ml in female individuals. However , the specific activity of individuals treated decreased in males (0.19 ± 0.04 nmol / min / mg ), but seems stable for females treated with 0.49 ± 0.26 nmol / min / mg. Similarly, individuals Schistocerca gregaria exposed to foliar extract of crude essential oils, reveal disturbances in neurochemical and behavioral responses, from which increased toxicity of this extract of C. Vulgaris.
