Abstract

This study aimed to evaluate different diets effects on the biological parameters of plodia interpunctella (Hubner). Three hosts namely; date, almond and peanut. Results showed that the hatchability percentage, weight per larva, pupation percentage and adult emergence percentage were the highest on almonds diet. Incubation period, generation time and life cycle were shortest in almonds. Also data indicated that almonds were the most preferred host. The efficacy of three microwave powers was investigated against two plodia interpunctella stages. The result cleared that the increase in microwave power and exposure times caused an increase in eggs and larvae reduction rate % and accordingly the microwave power more effective in larvae than egg stage. Also, results showed that there is no harmful effect on the chemical fruits characteristics under microwave treatment.
