Močan pojav ameriške koruzne sovke (Spodoptera frugiperda [J. E. Smith, 1797]) kmetom v Nigeriji od leta 2016 povzroča resne socio-ekonomske težave. V pričujoči raziskavi je bilo ovrednotenih dvajset sort koruze, prilagojenih agro-ekološkim razmeram v Nigeriji. Na petih lokacijah so preučevali odpornost sort na škodljivca, z namenom njihovega izboljšanja in uvajanja v pridelavo. Ocenjevanja so potekala v letih 2017 in 2018 v naravnih razmerah in v rastlinjaku. Podatki o pojavu škodljivca, obsegu poškodb zaradi gosenic in višini rastlin so se zbirali tedensko. Vsi poskusi so bili končani šest tednov po setvi. Sorte kot so SUWAN 1 SR, BR LNTP-Y C6, AMA TZBR-W C4 in TZBR ELD 4 C2 so se izkazale kot dober vir odpornosti na škodljivca in bi lahko bile uporabljene v programih za izboljšanje učinkovitosti zatiranja ameriške koruzne sovke.
