Abstract : Eldana saccharina Walker (Lepidoptera: Pyralidae) is the major pest of the South African sugarcane industry. Pest and Disease field teams based in each mill area of the industry monitor population levels and assess levels of damage in different parts of the industry. This information is used during the season to detect areas of high infestation that can be harvested to help reduce the detrimental effects of this pest. The survey data from 3 years of routine monitoring were summarized to show: (1) long-term population trends; (2) differences in cultivar susceptibility; (3) crop-age influences on E. saccharina. Additionally, these data provide baseline E. saccharina levels in different geographical localities within the industry. Generally, E. saccharina infestations are more serious in rain-fed areas than in irrigated sugarcane, some sugarcane cultivars are more susceptible than others, and infestations are usually higher in older crops. This paper illustrates the important points arising from the analysis of these survey data, and discusses the main factors that are known to influence infestation and damage levels of this pest in this industry.
