  abstract = {{T}he noctuid stem borer {B}usseola fusca is an important pest of maize and sorghum in {S}ub-{S}aharan {A}frica. {T}he presence of this species occurred mostly on cultivated than on wild habitats. {B}usseola fusca is oligophagous having a narrow range of a wild grass species. {T}his might be due, in part, to differences in silicon ({S}i) content in plant tissues between cultivated and wild grasses. {I}n the present study, we have tested this hypothesis by studying the survival and the relative growth rate ({RGR}) expressed as daily weight gains of {B}. fusca larvae on maize and six wild host plants, mostly present in the natural habitat where {B}. fusca occurred, and correlated with their {S}i contents. {S}urvival and {RGR} of {B}. fusca larvae were considerably higher on maize and wild sorghum than on the other grass species, and they were negatively related to plant {S}i content. {T}his was corroborated with results on {RGR} from artificial diets amended with increasing levels of {S}i. {I}n addition, if {S}i was added to maize growing substrate {B}. fusca larval growth was significantly reduced confirming the involvement of {S}i in {B}. fusca larvae - {P}oaceae interactions. {T}he results provide insight into the possible mechanisms of oligophagy of {B}. fusca and provide a correlative support for a physical role of plant endogenous {S}i in impeding feeding of {B}. fusca larvae.},
