تأثير مستخلص المركبات الفينولية الخام لأوراق نبات البمبر Cordia myxaفي الأداء الحياتي لبعوض الكيولكس Culex pipienes (Dipterta: Culicidae Culicinia)

Abstract

In this study,Crude phenols were extracted from the leaf parts of Cordia myxa to evaluate their biological activities on some biological aspects of Culex pipienes . Mortality rates of immature stages , developmental period and females productivity were used us biological criteria , by using different concentrations (1,7.5,5,2.5) mg⁄ml . The results of this study showed that leaves mortality significantly affected performance in some aspects of life for Culex pipienes have increased mortality larval stages of the insect and significant compared to the control group and adult reduced productivity dramatically
