Abstract

Red flour beetle, T. castaneum (Herbst) is worldwide and most destructive pest of stored products and is cosmopolitan in distribution. It is the most common pest of wheat flour. It also causes serious damage upon dried fruits, pulses and prepared cereal foods. Larvae and adults of this pest were treated with ozone as a gas at three concentrations (1, 3, and 5 g/m3) for six different periods (0.5, 1, 2, 3, 4 and 5 h.) compared with untreated insects. The results indicated that increasing the concentration and exposure period led to increasing the rate of mortality for both tested stages moreover to latent effect of ozone on pupation and adult emergence of this insect pest.
