Field resistance to fenitrothion in Oryzaephilus surinamensis was recorded for the first time from Queensland during 1979 in samples from 8 bulk storages where control failures had occurred. Resistance levels at the LC 99,9 ranged from 53x to 62x in tests with treated grain. For the strain most resistant overall, tests using the FAO impregnated‐paper method and treated grain assays showed resistance at the LC 50 to fenitrothion (159x and 53x), malathion (48x and 32x), pirimiphos‐methyl (37x and 19x), methacrifos (1.8x and 5.7x) and permethrin (3.2x and 4.0x).
