Abstract

Survival rates to pupal and adult stages, development rates, and pupal weights were determined for larvae of Mouralia tinctoides (Guenée) placed on six species of Commelinaceae. Larvae developed successfully on the dayflower, Commelina diffusa Burmeister, on two wandering jew species, Tradescantia zebrina G. G. Bosse and Tradescantia fluminensis Velloso, and on the spiderwort, Tradescantia ohiensis Raffinesque. Poor survival and lower pupal weights occurred with larvae placed on foliage of purple queen Tradescantia pallida (Rose) D. Hunt and on Callisia repens L. Larvae of M. tinctoides did not survive on two artificial diets used as rearing media for many pest Lepidoptera or on foliage of cotton, Gossypium hirsutum L. /// Se determinaron las tasas de supervivencia de las etapas pupales y imaginales, tasas de desarrollo, y pesos pupales para larvas de Mouralia tinctoides (Guenée) colocadas sobre seis especies de Commelinaceae. Las larvas se lograron de desarrollar con éxito sobre canutillo, Commelina diffusa Burmeister, y sobre Tradescantia zebrina G. C. Bosse y T. fluminensis Velloso y sobre T. ohiensis Raffinesque. Supervivencia deficiente y peso pupal más bajo ocurrió en las larvas colocadas sobre follaje de T. pallida (Rose) D. Hunt y sobre canutillo rastrero, Callisia repens L. Las larvas de M. tinctoides no sobrevivieron ni sobre dós dietas artificiales usadas como medios de criar para muchos lepidópteros plagas, ni sobre el follaje de algodón, Gosypium hirsutum L.
