BAVARESCO, Alvimar et al. Adaptation of an artificial diet for Spodoptera cosmioides (Walk.) (Lepidoptera: Noctuidae) laboratory rearing. Neotrop. Entomol. [online]. 2004, vol.33, n.2, pp.155-161. ISSN 1519-566X.

The biology of Spodoptera cosmioides (Walk.) was studied on three artificial diets with different protein sources (d1 = white bean, yeast extract, soybean flour, powder milk and wheat germ; d2 = 'carioca' bean and yeast extract; d3 = corn flour, wheat germ and yeast extract). The objective of this research was to determine the most suitable diet for mass rearing S. cosmioides in laboratory. The species is highly polyphagous, and for this reason we hypothesized that diets that are suitable for other Lepidoptera can allow its development and fulfill the minimum requirements of biological quality, quantity and economy. Although S. cosmioides has completed the biological cycle on the three diets, the d1 was the most suitable for its rearing and produced the fastest development, higher total survival and pupae weight, as well as higher net reproduction rate (Ro), intrinsic rate of natural increase (rm) and finite rate of natural increase (l). The number of instars varied from six to seven, predominating six in d1 and d3; in d2, half the population presented six instars and half seven. Females presented pupae duration significantly lower that the males in all diets, thus emerging earlier. Adult longevity was not affected by the diets, while total fecundity was higher in d1 and d2. In conclusion, the diet 1 is recommended to mass rearing S. cosmioides in the laboratory.
