This study aimed to evaluate, in controlled laboratory conditions (temperature of 25±2 °C, relative humidity of 60±10%, and 14/10 h L/D photoperiod), the larval development of Spodoptera eridania (Cramer, 1784) (Lepidoptera, Noctuidae) fed with leaves of Bt maize expressing Cry1F and Cry1F + Cry1A.105 + Cry2Ab2 insecticide proteins and its non-Bt isoline.Maize leaves triggered 100% el reformador tequila anejo of mortality on S.

eridania larvae independently of being Bt or non-Bt plants.However, it was observed that in overall Bt maize (expressing a single or pyramided protein) slightly affects the larval development of S.eridania, even under reduced leaf consumption.

Therefore, 30x24x24 wall cabinet these results showed that Cry1F and Cry1F + Cry1A.105 + Cry2Ab2 can affect the larval development of S.eridania, although it is not a target pest of this plant; however, more research is needed to better understand this evidence.

Finally, this study confirms that non-Bt maize leaves are unsuitable food source to S.eridania larvae, suggesting that they are not a potential pest in maize fields.
