Efficacy of Bt‐(Cry1Ab + Cry2Ab + Cry1Fa) maize against Spodoptera frugiperda and other lepidopteran migratory pests in tropical Asia

The invasive fall armyworm Spodoptera frugiperda and other lepidopteran migratory pests significantly threaten maize production in tropical Asia, a key year‐round breeding region and source of spring or summer migrants across the broader Asian region. The strategic deployment of genetically modified maize expressing pyramided Bacillus thuringiensis (Bt) toxins offers a promising approach for managing multiple pests and delaying resistance evolution in this region. This study evaluated the insecticidal efficacy of Bt maize (LP026‐2 event, Cry1Ab + Cry2Ab + Cry1Fa) against six major lepidopteran pests: S. frugiperda, Mythimna separata, Spodoptera exigua, Spodoptera litura, Helicoverpa armigera, and Ostrinia furnacalis.
