Cotton stem borer, Eudnobothurs brasiliensis damage showed a graded distribution from Lhe margin of the field to the middle. Infestation was considerably higher in the border rows than in the center of the field. The study documented the behavior of this pest during the period when it migrates from overwintering sites around the field to cotton. The results confirm former observations that the levels of infestation are higher near humid overwintering areas with permanent vegetation, Early planted blocks of cotton had the highest rates of infestation, often reaching 70% of plant mortality. In later plantings a 20% reduction in plant mortality was observed every time planting was delayed for ten days. The data suggest that this pest may be co...
