  abstract = {{I}nteractions within and between species sharing the same resources are characterised by competition or facilitation, and can be influenced by factors such as larval numbers and phenotypic plasticity of the interactions. {T}he effect of larval density on the survival and relative growth rate of the stemborers {B}usseola fusca ({F}uller) and {S}esamia calamistis {H}ampson (both {L}epidoptera: {N}octuidae), and {C}hilo partellus ({S}winhoe) ({L}epidoptera: {C}rambidae) were studied, as well as the temporal plasticity of their competitive interactions. {T}hese stemborers attack maize crops ({Z}ea mays {L}.) ({P}oaceae) in sub-{S}aharan {A}frica. {E}xperiments were conducted in the laboratory under controlled conditions at the optimum development temperature (25 degrees {C}) for the three species. {S}urrogate stems filled with artificial diet were intra- and interspecifically infested with larvae of each species. {T}he effect of larval density on competition was studied at low (six larvae) and high (12 larvae) levels of infestation, whereas the temporal plasticity of competition was evaluated at 7, 14, 21, or 28days after infestation. {T}he two experiments involved single- and multi-species infestation treatments. {L}arval numbers and wet mass in each artificial stem were recorded in each experiment. {S}urvival and relative growth rate of the three species were significantly higher at low-infestation levels when facing either intra- or interspecific competition. {T}he intensity of competition was also temporally plastic among the species and increased as the duration of competition increased. {T}hese results are discussed in terms of general infestations of cereal crops by borers.},
