Effectiveness of some botanical insecticides against Spodoptera littoralis Boisduvala (Lepidoptera: Noctudiae), Myzus persicae Sulzer (Hemiptera: Aphididae) and Tetranychus urticae Koch (Acari: Tetranychidae)

Abstract

Biological efficiency of botanical insecticides was determined that were obtained from <i>Pongamia glabra</i>, <i>Azadirachta indica</i> and <i>Chrysanthemum cinerariifolium</i> against <i>Spodoptera littoralis</i>, <i>Myzus persicae</i> and <i>Tetranychus urticae</i> on greenhouse plants. In all the tested extracts, the highest concentration caused 100% mortality. In the other tested concentrations, a conclusive difference in efficiency was found; on day 12 after application, the highest efficiency was determined for <i>M. persicae</i> pongam oil, for <i>T. urticae</i> and <i>S. littoralis</i> neem oil.
