Cover Story: The fall armyworm (Spodoptera frugiperda) is a devastating pest for multiple crops, especially corn. Transgenic corn producing insecticidal proteins from Bacillus thuringiensis (Bt corn) controls S. frugiperda, although practical resistance exists in the Western Hemisphere. The long-distance flight capacity of S. frugiperda is of concern given its ongoing global spread and possible resistance dispersal. We used rotational flight mills in testing exposure to Bt insecticidal proteins on flight tendency in S. frugiperda moths, including susceptible and resistant populations. Results support that a generally lethal exposure of S. frugiperda larvae to Bt proteins increases the tendency for longer female moth flights in susceptible but not resistant moths. This information helps understand factors affecting the migratory spread of S. frugiperda and its implications for resistance management. View this paper
