Estudio complementario de la fecundidad y ciclo evolutivo de Corcyra cepholonica (Stainton) (Lepidoptera Galleriinaea), con vistas a su utilización en la cría artificial del Trichogramma (Hymenoptera, Trichogrammatidae)

Abstract

The fertility of the Corcyra cephalonica (Stainton) Moth increases significantly when rice powder is used as feeding material for the larvae, provided that temperature and relative humidity are maintained under optimal conditions, as was reported at the Conference of the Association of Cuban Sugar Cane Technicians (ATAC) (Torre, 197 a). It was also observed that the life cycle is shortened when rice powder to used. The index of development obtained by the use of this feeding material is higher than that obtained by the use of corn powder, as was reported at the same Conference (Torre, 197 b). It was noted that the duration of the life cycle is not affected by the amount of food available to the larvae, where as the size of the specimens, as well as the natality period, are indeed affected. It has been determined that the minimal amount of food- needed for. the complete development of this Moth is 0 .04 g.
