Insecticidal Activity of Lantana Camara on Maize Weevils (Sitophilus Zeamais Motsch.).

Laboratory experiment was conducted in order to evaluate the toxicity potential of parts of Lantana camara (leaf, flower and mixture of leaf and flower) powder at a rate of 5 gm per 100 gm of maize grain (W: W) as a possible control of maize weevils (Sitophilus zeamais Motsch.). The study was conducted at Wolaita Sodo University Plant Sciences laboratory using CRD with three replications twice. Maize variety used for the experiment was BH540 and Malathion 5% dust and untreated check were included for comparison. The experiment revealed that all Lantana camara parts used in the experiments as a treatment caused high adult weevils mortality and reduce F1 progeny emergence. Comparatively lantana leaf powder showed better performance in its insecticidal activity against maize weevils (S. zeamais).
