Abstract

Currently, Hyphantira cunea Drury, the fall webworms (FWW), is one of the most severe insect pest for various landscaping trees and mulberry trees. In this study, we investigated whether FWW might be managed by Sodium saccharin (SAC) which is a food additive and not toxic to humans and environment. We found that FWW larvae treated with various concentrations of SAC showed dose-dependent delayed development and low survival rates. The lethal-concentration 50% of FWW larvae to SAC was 0.03 M. We also confirmed that SAC can be used to control FWW larvae attacking mulberry trees in the field. Compared to not-treated or tap-water-spraying control groups, SAC-spraying groups showed significantly higher mortality rates of FWW larvae (56.2%). Thus, SAC can be used for control FWW larvae in mulberry trees.
