  abstract = {{I}n {C}ameroon, the noctuid {B}usseola fusca is the most important pest of maize. {T}he braconid {C}otesia sesamiae, which is the most common larval parasitoid of noctuid stemborers in eastern {A}frica, was absent on {B}. fusca attacking maize. {T}hus, it is planned to introduce several strains of the parasitoid from {K}enya. {P}re-release surveys were undertaken in major maize growing areas to catalogue stemborer species, and larval and pupal parasitoids on maize and four wild host plant species. {O}n maize, {B}. fusca was the predominant borer in all ecozones except for the lowland coastal forest, usually accounting for 60-99%, followed by the pyralid {E}ldana saccharina in the forest zone and the crambid {C}hilo sp. in the mid-altitudes. {C}ontrary to what was reported before, the noctuid {P}oeonoma serrata - and not {B}. fusca - was the predominant borer on elephant grass, constituting 70-96% of all borers. {O}n wild sorghum in the forest zone, the noctuid {S}esamia poephaga was the most abundant species, while on {P}anicum sp., {C}hilo sp. predominated. {O}n {S}etaria megaphylla in the forest zone, {C}hilo sp. was the most abundant species followed by {B}usseola quadrata. {B}usseola fusca was scarce on all wild grass species, indicating that previous reports on the predominance of this pest species on wild host plants were the result of misidentifications. {T}hree tachinid and 16 hymenopteran parasitoids were obtained, most of them from {B}. fusca and {P}. serrata, on maize and {P}ennisetum purpureum respectively. {C}. sesamiae was scarce and never recovered from {B}. fusca on maize. {I}n view of the new findings, acceptability and suitability studies involving the different stemborer species identified from wild plant hosts are required to determine if they will form a reproductive sink or perennate {C}. sesamiae populations during the off-season when maize is scarce and {B}. fusca is diapausing.},
