The attack's intensity was carried out by counting the number of leaves showing symptoms of an attack on the top leaves. Calculation of the proportion of attacks was carried out by the Davis method. The results showed that the highest S. frugiperda population at the age of 14 days after planting. The intensity of S. frugiperda attack on maize was relatively high at the age of 42 days after planting, with an average attack of 65.24%.
