| Abstract | ||||
| The lethal effect of Melia azedarach, Duranta plumieri, Venca roses, Clerodenderon inerme, Ruta graveolens, Colocasia antiquorum, Allium cepa and Allium sativum leaves on Ostrinia nubilalis larvae were tested in the laboratory. The larvae were fed either on an artificial diet containing the paste or the powder of the tested leaves or on fresh mai-Le plants sprayed with the leaf extracts. C.inerme, D.pulmieri, V.rosea and M.azedarach leaves showed high efficiency; killed 55-100% of the newly hatched larvae and reduced the weights of the survivals with 41.8-94.3%. On the other hand, C.antiquorum, A.cepa, A.sativum and R.graveolens leaves represented the least toxicants against 0.nubilalis larvae. The acetonic extracts were more toxic than those of diethylether. | ||||
