fisiológica) y bajo peso pupal, con el uso de estas dietas artificiales se incrementó la mortalidad juvenil y en los adultos obtenidos decreció la fecundidad, longevidad y fertilidad, mientras que cuando se alimentaron con huevos de S. cerealella, los anteriores parámetros biológicos se mantuvieron en un nivel constante durante la segunda y tercera generación. Al utilizar las tres dietas artificiales ensayadas en la cría de adultos de C. cubana se logró una alta fecundidad, fertilidad y longevidad, obteniéndose en promedio 490; 493 y 458 huevos/hembra/28 días.
of the precceding diets and the one used by Vanderzant, (1973). With the first diet which showed better results, the testing kept on for three consecutive generations; the average duration of development of the early stages was 35,23 days compared to 17,3 days when they were fed with S. cerealella eggs, the average pupal weight was 6,3
mg wiht diet number one compared to 8,6 mg when S. cerealella eggs were used. Besides the increase in the development duration of early phases up to maturity stages
(physiological disdjustment) under pupal weight with fictitious diets use, juvenile mortaly was increased and in the grown - ups obtained decreased the fecundity, longevity and fertility, while when feeding was with S. cerealella eggs the preceeding standards of biological nature kept a constant level during
second and third generations. In the using of three the tested artificial diets in the rearing of adults of C. cubana high fecundity was reached as well as fertily and longevity with
490, 493 and 458 eggs/female/28 days average.
