Busseola segeta, a Potential New Pest of Maize in Western Kenya

Abstract

In sub-Saharan Africa, Busseola fusca (Fuller) (Lepidoptera, Noctuidae) is considered as one of the major stem borer pests of maize (Zea mays) and sorghum (Sorghum bicolor) [1]. Recent surveys in Western Kenya indicated the presence of another Busseola species on maize, Busseola segeta Bowden (Lepidoptera, Noctuidae) [2,3]. Busseola segeta can develop on at least nine host plants, including Napier grass (Pennisetum purpureum), maize and sorghum spp. [4]. We investigated the composition of stem borer pest communities in a cultivated plot in Western Kenya in a location known to cultivate maize continuously throughout the year.
