Pers.) was carried out. The diets used determined changes in diverse parameters such as duration of life cycle, number of larval instars, sex ratio, life expectancy, fertility and/or fecundity. Regarding to the life cycle duration, significant differences among host plants were recorded for the different developmental stages. Females fed on a corn diet showed a fertility of 92.1%, while those breeding on a diet based on Guineagrass showed 96.4% and 99.8% on Bermudagrass. Mean daily egg production ranged within 99.4 (fed on Bermudagrass) and 187.8 (fed on Guineagrass). Total mean egg production also varied with larval diet; maximum value was recorded for females fed on Guineagrass leaves (0 1282.7 ± 38.6 eggs/females). Results suggest that individuals bred on this grasses during final winter could play an important rolein FAW population dynamic performance affecting corn crops in Argentina´s Norther Region. 2004 artículo científico 0065-1737 https://www.redalyc.org/articulo.oa?id=57520115 en http://www.redalyc.org/revista.oa?id=575 Acta Zoológica Mexicana (nueva serie) application/pdf Instituto de Ecología, A.C.
