Methanol and diethyl ether extracts of Harmal, Rhazya stricta Decne.; neem seed kernels, Azadirachta indica A.Juss; cloves, Syzygeum aromarticum (L.); citrus peel and Ramram, Heliotropium bacciferum (Forssk-) were evaluated for their deterrence to oviposition by Callosobruchus maculatus (F.) on chickpeas in choice tests. Both extracts of all materials significantly reduced oviposition on treated seeds. Maximum deterrent effects (91.8%) were obtained in the neem seed methanol extract at 0.5% concentration, citrus peel O. l% ether extract (90.9%), R stricta 0.5% methanol extract (83.9%), and clove 0. 1% ether extract (80.0%). Methanol extracts of neem seeds and R.
