Forum: Suitability of Six Species of Commelinaceae as Larval Hosts of Mouralia Tinctoides (Lepidoptera: Noctuidae, Plusiinae)

Peter J. Landolt


Survival rates to pupal and adult stages, development rates, and pupal weights were determined for larvae of Mouralia tinctoides (Guenee) 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.
