The Mexican rice borer, Eoreuma loftini (Dyar), is an invasive pest of rice, Oryza sativa L., in the Gulf Coast region of the United States. This pest also damages sugarcane, Saccharum spp. hybrids; corn, Zea mays L.; and sorghum, Sorghum bicolor (L.) Moench, and feeds on weedy noncrop grasses. Multiple aspects of integrated pest management including use of pheromone traps, manipulation of planting dates, harvest cutting height, stubble management, noncrop host management, soil fertility management, host plant resistance, use of insecticides, and biological control have been studied for Mexican rice borer management. However, the current management strategy in rice primarily relies on the use of chlorantraniliprole insecticide seed treatments. This profile addresses Mexican rice borer biology and management in rice in the United States.

The sugarcane beetle, Euetheola humilis (Burmeister), is a significant pest of sweetpotato, Ipomoea batatas (L.), and corn, Zea mays L., but can also be problematic in turf, rice, Oryza sativa L., and sugarcane, Saccharum spp. hybrids, in the southeastern United States. The adult is the damaging stage in all crop production systems. Injury to sweetpotato occurs during the fall prior to harvest, whereas injury to field crops occurs in the spring. Adult beetles chew jagged lesions in the sweetpotato roots, which drastically affects marketability of the crop. Injury in corn often results in stand losses and yield reductions. We discuss the life history, ecology, plant injury, and management of the sugarcane beetle as it relates to sweetpotato and field corn production in the southeastern United States.
