  abstract = {{L}epidopteran stem-borers in {A}frica are attacked by diverse natural enemies in natural and cultivated environments. {F}ield surveys of stem-borer natural enemies and associated host plants were conducted during the austral summers of 2014/15 and 2015/16 on natural and cultivated habitats across {B}otswana to determine their diversity and relative abundance. {I}n cultivated habitats, the most common parasitoids of larvae were {C}otesia flavipes {C}ameron, {C}. sesamiae ({C}ameron), and of pupae, {P}ediobius furvus {G}ahan and {G}ambroides nimbipennis {S}eyrig. {I}n natural habitats, the larval parasitoids {C}helonus curvimaculatus {C}ameron and {G}oniozus indicus {A}shmead were recorded, along with the pupal parasitoid, {D}entichasmias busseolae {H}einrich. {F}urthermore, the predatory ants {L}inepithema humile {M}ayr, {C}rematogaster peringueyi {E}mery and {A}enictus species were recorded in both cultivated and natural habitats. {T}he major cultivated plants hosting stem-borers and related natural enemies were maize, sorghum, sweet sorghum, and the major wild plants were {E}chinochloa pyramidalis, {T}ypha latifolia, {S}choenopkctus corymbosus and {C}yperus dives. {C}hilo partellus {S}winhoe and {S}esamia spp. were the major hosts for parasitoids, with {C}. partellus predominating in cultivated habitats and {S}esamia jansei {T}ams & {B}owden in natural habitats. {L}arval parasitism ranged from 2.1 to 34.7% and 3.3 to 14.3% in cultivated and natural habitats respectively, whereas pupal parasitism ranged from 6.1 to 10.6% and 6.7 to 9.1%, respectively. {P}arasitoid percentage abundance ranged from 1.1 to 41.6% and 4.8 to 38.1% in cultivated and natural habitats respectively, with {C}. flavipes dominating in cultivated and {C}. curvimaculatus in natural habitats. {O}ur results show that cultivated and natural environments in {B}otswana harbor a diverse natural enemy community worthy of conserving for stem-borer biological control.},
