Ovicidal and Larvicidal activity of Schanginia aegyptiaca leaf extracts against Dialerodus citri (Ashmead) (Homoptera: Aleyrodida)

Abstract

Methanolic and hexane extracts of Schanginia aegyptiaca were tested against different developmental stages of Dialerodus citri in laboratory bioassays . The obtained results revealed that methanol and hexane extracts significantly affected the mortality of different developmental stages of Dialerodus citri . The results of the present study suggested that the hexane extract were less effective than the methanolic extract atdifferent concentrations (2 , 1 , 0.5 ) % .
