Abstract:  [Objectives]  In order to determine the effective pesticide to control Megabruchidius dorsalis (Fahraeus). [Methods] Three pesticides, chlorfluazuron, chlorpyrifos and methomyl, were applied to adults, newly hatched larvae and eggs of M. dorsalis at field-recommended concentrations. [Results]  Chlorfluazuron, chlorpyrifos and methomyl killed larvae effectively with mortality rates of 96.59%, 100.00% and 100.00%, respectively after 72 h. Chlorpyrifos and methomyl killed 100.00% and 94.38% of adults after 72 h. Chlorfluazuron was not effective with respect to eggs and adults. [Conclusion]  Field-recommended concentrations of methomyl is the most toxic insecticide to M. dorsalis.
