Abstract
In view of the increased interest that has been shown in maize stalk borers on the coast of Kenya, it seems desirable to summarize the work that was done at Mtwapa Research Station in 1961 and 1962 on the more basic aspects of these pests. The different species are described by Wheatley (1961). Contrary to his findings, however, more recent experience has shown that the coastal stalk borer Chilo argyrolepia (Hmps.) can be a major pest. In 1961 approximately 95 per cent of all caterpillars bred out from samples taken in the field at low altitudes were the spotted stalk borer Chilo partellus (Swinh.) but in 1962, that proportion consisted of C. argyrolepia. Sesumia calami.ltes (Hmps.),the pink stalk borer, was rare in both years.
