ABSTRACT

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.
