  abstract = {{C}ompetition or facilitation characterises intra-and interspecific interactions within communities of species that utilize the same resources. {T}emperature is an important factor influencing those interactions and eventual outcomes. {T}he noctuid stemborers, {B}usseola fusca and {S}esamia calamistis and the crambid {C}hilo partellus attack maize in sub-{S}aharan {A}frica. {T}hey often occur as a community of interacting species in the same field and plant at all elevations. {T}he influence of temperature on the intra-and interspecific interactions among larvae of these species, was studied using potted maize plants exposed to varying temperatures in a greenhouse and artificial stems kept at different constant temperatures (15 degrees {C}, 20 degrees {C}, 25 degrees {C} and 30 degrees {C}) in an incubator. {T}he experiments involved single-and multispecies infestation treatments. {S}urvival and relative growth rates of each species were assessed. {B}oth intra-and interspecific competitions were observed among all three species. {I}nterspecific competition was stronger between the noctuids and the crambid than between the two noctuids. {T}emperature affected both survival and relative growth rates of the three species. {P}articularly at high temperatures, {C}. partellus was superior in interspecific interactions shown by higher larval survival and relative growth rates. {I}n contrast, low temperatures favoured survival of {B}. fusca and {S}. calamistis but affected the relative growth rates of all three species. {S}urvival and relative growth rates of {B}. fusca and {S}. calamistis in interspecific interactions did not differ significantly across temperatures. {T}emperature increase caused by future climate change is likely to confer an advantage on {C}. partellus over the noctuids in the utilization of resources (crops).},
