South American Rice Miner (SARM) - Hydrellia wirthi (Korytkowski)
Economic injury to rice plants tends to occur in young rice from emergence until the tillering stages, particularly in late-planted fields (planted in May and June in central and southwest Louisiana). Injury is caused by the larva or maggot, which causes large, elongated lesions along the margins of emerging leaves. Field damage is distributed in large patches either in the center or along the margins of the field.
