Environmental friendly pesticides with a natural origin can be used as an alternative to chemicals in plant pests control programs. Lentil weevil, Bruchus lentis Frӧlich, is one of the important pests of stored gram and pulses. Lentil weevil, B. lentis has developed resistance against fumigants and synthetic insecticides in developing countries. These chemicals are a big source of environmental pollution and also affect the non target animals. This study was carried out in order to find alternate control program for management of insect pests seen in stored pulses. Therefore, the present project was conducted in order to evaluate the effect of different doses of Melia azedarach L. (White cedar), Achillea wilhelmsii L. (Yarrow) and Allium sativum L. (Garlic) powders on adult population of B. lentis. The triply replicated experiment, using Completely Randomized Design (CRD), was carried out in the Agricultural and Natural Research Center of Yasouj, Iran. Three different doses (2.0g, 3.0g and 4.0g per 100g of grains) of each plant powder were used. The data for percent mortality was collected after three different exposure times (20, 40 and 60 days). Collected data was analysed statistically using Statistical software. Results indicated that among the different extracts, maximum mortality of adult lentil weevil was caused by powder of white cedar compared to other studied plants such as garlic and yarrow. Garlic showed maximum reduction of lentil weevil compared to yarrow.
