Abstract:

Survey were conducted to collect storage pests such as red flour beetle, Tribolium castaneum and rice weevil, Sitophilus oryzae from twenty three different government storage warehouses of the Tamil Nadu. Phosphine resistance in T. castaneum ranged from 91.67 to 100 per cent while in S. oryzae ranged from 66.67 to 90 per cent. About 91.67 per cent of maximum phosphine resistance was recorded in Nagarkoil, TNCSC. Considering S. oryzae, highest resistance level (90%) was recorded in Trichy, TNCSC while Pudukkottai, TNCSC showed lowest resistance level (66.67 %). Improper sealing with sub-lethal dosage of phosphine leads to phosphine resistance. Poor sanitation made the few resistant population to breed with susceptible population to develop heterogenous population over the period leading to development of resistance.
