Abstract : The efficacy of postharvest dips and sprays of dimethoate and fenthion at 400 mg/litre against the tephritid Dacus tryoni on stored tomatoes and mangoes was investigated in Australia. These treatments achieved quarantine security levels of 99.99% mortality for tomato and 99.5% mortality for mango. Residues on tomato did not exceed the maximum residue limits prescribed by regulation in Australia of 1 mg/kg for dimethoate and 2 mg/kg for fenthion. Residues on mango were below the maximum residue limit at all times. It is concluded that dimethoate and fenithion are viable alternatives to ethylene dibromide for fruit fly-susceptible commodities traded within Australia.
