Numbers of individuals (adults + nymphs) per locations ranged from 0 to 12. The highest density was 0.3 per stalk in a field in St. Mary Parish. When the sugarcane delphacid was initially found in Florida, densities ranged from 0.5 per stalk to 35.7 per stalk (Sosa 1985). No oviposition was detected; oviposition was obviously occurring but apparently at such low
levels that it was not detected.
