| Abstract The aim of this study to evaluate the effect of four concentrations (25,50,75,100% ) of stems extractions of Sonchus Oleraceus L. plant on the beetle Coccinella septempuncta L. in devouring insects from the black broad-bean and the green plums . The practical experiments show that the concentration 100% givens the highest killing ratio which reaches 80% after 48 hours in compared with the rest concentrations respectively .Theresults of the current study showed that the concentration 75% and the concentration 50% gives 40% and 30% Killing ratio respectively whereas the concentration 25%gives the lowest Killing ratio which reaches 13.3% finally the current study showed that the direct treatment of the ladybugs with Sonchus Oleraceus L. plant extraction gave the highest killing ratio with the concentration 100% which reaches 83.3% exceeding other concentration while the concentration 25% gives the lowest Killing ratio which reaches 13.3% . | ||
