This study investigated the lethal and transgenerational effects of botanical synthetic insecticides on egg parasitoid Trichogramma atopovirilia, an important natural enemy Spodoptera frugiperda in Brazil beyond. The treatments were assessed for their impact parasitism, emergence, sex ratio, flight capacity adults exposed to contaminated eggs. insecticide ESAM (ethanolic seed extract Annona mucosa) significantly reduced parasitism F0 generation by 99.76%, categorizing it as toxic. Anosom® [acetogenins (annonin a major component)] Azamax® [limonoids (azadirachtin + 3-tigloilazadirachtol)] also caused substantial reductions (99.13% 92.36%, respectively) rate. EFAMON leaf montana) 62%, while Premio® (chlorantraniliprole) resulted 28.21% reduction. In F1 generation, emergence rates EFAMON, Azamax®, exceeded 70%, showing no significant differences from negative control (82%), lower rate 61.39%. No observed ratio or F2 generations. Most reached high (above 80%). These results indicate that was toxic, other showed effects. Our findings contribute understanding selectivity highlight importance such studies sustainable management S. within integrated pest programs.
