In the present study essential oils like neem-azal, clove oil and acorus oil were tested at different concentrations for the management of red flour beetle, Tribolium castaneum (Herbst). Neem-azal at 2.0 per cent was found to be effective with LC50 value of 1.11 per cent and LT50 value of 2.4 days followed by acorus oil 15.0 per cent with LC50 value of 16.43 and LT50 value of 4.30 days against Tribolium larvae. Neem-azal at 2 per cent was found effective with LC50 of 0.99 per cent and LT50 value of 15.78 hours followed by clove oil 15.0 per cent with LC50 of 11.30 per cent and LT50 value of 45.07 hours against Tribolium adults.
