CURIS, M. C; BERTOLACCINI, I  and  LUTZ, A. Efecto de dietas en adultos de Spodoptera cosmioides (Lepidoptera: noctuidae) sobre la fertilidad, fecundidad y longevidad del adulto. FAVE. Secc. Cienc. agrar. [online]. 2017, vol.16, n.2, pp.17-24. ISSN 1666-7719.

The occurrence of the Bt + RR2Y soybean cultivars determined the appearance of a new pest, Spodoptera cosmioides, a highly polyphagous, widely distributed pest. Insect breeding in chambers is necessary for basic and applied research. The aim of the work was to evaluate the effect of three diets rich in carbohydrates (honey solution, glucose syrup and corn syrup) in the diet of adults and to determine their effect on fertility, fecundity and survival of S. cosmioides. It was determined that, although no differences were found between the treatments, the composition of the diets sugars can affect the reproductive parameters of this pest, since the females fed with solution of natural honey, rich in organic compounds, increased fertility, reflected in greater egg laying and hatching and longevity of adults.

Keywords : Artificial breeding; Carbohydrates; Adult diets.
