  abstract = {{I}n addition to destroying the leaves, stems, pods, and grains of soybean ({G}lycine max), {S}podoptera frugiperda larvae may also have the cut off behavior in the seedlings close to the ground, harming the establishment of the soybean crop. {T}herefore, this study aimed to evaluate the consequences of the fall armyworm attack by adopting the cut off behavior, which has been similarly documented for black cutworm ({A}grotis ipsilon) in newly emerged soybean plants. {T}he treatments were five levels of infestation with 0, 5, 10, 20 and 40 larvae per m2. {T}hree variables were assessed: (1) stand (relationship between attacked and initial number of plants), (2) types and amounts of injured structures, such as hypocotyl (embryonic shoot), and the cotyledons (seed leaves), and (3) level of defoliation. {T}he variables were collected every 24 hours until the pupal stage. {A}dditionally, the final stand of the seedlings was quantified, with the highest injury intensity observed in the plots that contained the highest number of larvae. {I}n the second experiment, the dynamics of movement and attacks of plants by {S}. frugiperda larvae at the following times of the day: 07:00, 10:00, 13:00, 16:00, 19:00 and 21:00 were analyzed with supervised machine learning models. {T}he injury caused by {S}. frugiperda with the behavior of the cut off and the voracity of the larvae were evident in the structures (hypocotyl and cotyledons) of the evaluated plants. {T}he results of the present study emphasize the need to manage {S}. frugiperda during the preplanting phase of soybean.},
