Abstract

The feeding damage caused by the southern corn billbug, Sphenophorus callosus (Olivier), to corn seedlings was studied under selected cultural treatments during 1983 - 84. The growth and development of light, medium, and severely damaged seedlings was observed until harvest. Significantly lower feeding damage and higher yields occurred in conventional tillage as compared with no-tillage treatments. Planting time applications of terbufos at 0.2 kg ai/1000 linear m produced significant control of infestations in 1983 when moisture was higher than normal, but not 1984. Mortality of the plants categorized as severely damaged was significantly lower for subsoiling, insecticide, and conventional tillage treatments than for no subsoiling, no insecticide, and no-tillage treatments in 1984.
