Biology of European corn borer was studied under laboratory condition of 25 + 10 temperature, 75 = 10 % RH and 16 : 8 hrs, photoperiod. In addition life tables were constructed under field condition to determine the mortality of each immature stage. Under laboratory conditions, the development of egg, larvae and pupal stages were found to be 5.23 + 0.08 (4-6); 17.00 + 0.12 (16-18) and 8,67 + 0.80 (5-18) days, respectively. Life tables indicated that the mortality from the egg stage to the first instar larva varied between 58 to 92 %. The mortality observed on each generation varied between 90.60 to 97.47 %
