  abstract = {{T}he fall armyworm ({FAW}), {S}podoptera frugiperda ({J}. {E}. {S}mith; {L}epidoptera: {N}octuidae), is an invasive pest that has recently become a major worldwide threat for maize production. {G}reatest crop yield reductions occur following damage by {FAW} larvae at early vegetative plant stages, between the first and second week after plant emergence. {I}n this study, field and semi-field experiments were carried out to assess the effect of cyantraniliprole-based seed treatment on the protection of early stages of maize plants against {FAW} and the associated mechanisms. {I}n the field, maize seed treatment using cyantraniliprole ({F}ortenza ({R})) significantly reduced the percentage of infested seedlings (77%) and the percentage of seedlings with severe damage (86%) up to 3 weeks after emergence. {I}n a choice situation, semi-field experiments showed that gravid moths preferred to lay eggs on plants from untreated seeds (68%) rather than on plants from treated seeds. {T}o the best of our knowledge, this is the first evidence that insecticide residues present in plant tissues deter oviposition of {N}octuid moths. {S}eed treatment with cyantraniliprole also reduced plant infestation (65%) 10 days after artificial inoculation of neonate larvae at 3 weeks after plant emergence, reducing the severity of leaf damage (by 67%). {I}nsecticide seed treatment is a relevant tool for the integrated pest management of the {FAW} in high-value crops such as sweet corn, especially for reducing foliar applications of insecticides during the most susceptible stages of the crop, as far as the risk of impacts on non-target organisms is low and no alternative biocontrol option is available.},
