The effect of infection by a fungal epiphyte (Ephelis japonica Hennings), presents on Digitaria eriantha Stent and Cynodon pletostachyrus (K. Schm.) Pilger on the feeding of two insects, an armyworm, Mythimna (Pseudaletia) separata (Walker), and a grasshopper, Aiolopus thalassinus tamulus (Fabricius), was investigated. M. sepatara larvae significantly preferred E. japonica-free leaves compared to E. japonica-infected leaves of D. eriantha, but no significant difference on the feeding preference on E. japonica-infected leaves of C. pletostachyrus. While the adults of A. t. tamulus preferred E. japonica -free to E. japonica-infected leaves of D. eriantha and C. pletostachyrus. Adults of A. t. tamulus that fed on E. japonica-free D. eriantha leaves survived over a significantly longer period of time than those that fed on E. japonica-infected leaves. These sutudies indicate the presence of some factor (s) associated with leaves of the two E. japonica - infected grasses.
