520			_aTwo indigenous maize cultivars, Inbred A and Nyamula were evaluated in a field trial for their susceptibility/resistance to Chilo partellus at the artificial infestation levels of 10 larvae/plant and 20 larvae/plant. Foliar damage was caused predominantly by C. partellus, but stem-tunnelling was caused not only by C. partellus but also by another species of borer, Eldana saccharina, which invaded the crop during the tassel emergence stage and persisted during harvest. In the 10-week old crop, the number of C. partellus recorded on Nyamula was greater than on Inbred A, but the incidence of injury to foliage and stem-tunnelling on the two cultivars was the same. At harvest the degree of damage to the two cultivars varied. At the infestation level of 20 larvae/plant, the cultivars suffered equal stem-tunnelling. There was a significant negative correlation between stem-tunnelling and yield for Inbred A, but the correlation was not significant for Nyamula. At infestation level of 10 larvae/plant, the correlation between stem-tunnelling and yield was not significant for either of the cultivars, perhaps, due to excessive activity of E. saccharina in the stalk of Inbred A
