Nictemeral variations for pacu Caranha, Piaractus mesopotamicus (Holmberg, 1887) culture in single - phase BABT
Barreto,Luiz Eduardo Guimarães de Sá; Igarashi,Marco Antonio; Hayashi,Carmino.
Studies related to nictemeral variation were executed in a fish growing pond, during all the seasons of the year, collecting data for dissolved oxygen; temperature; pH and electrical conductivity at the feeding channel on pond's surface, bottom and at streamlet bed. The results showed that Autumn was the season which had the lowest values of water temperature, the interval points, during Spring time, had superior average values of temperature when compared to the ones that were observed at external points. The lowest and highest index of pH were during Autumn season. The electrical conductivity didn't show significant differences during Autumn season. The samples obtained from the streamlet had very high significant differences with the samples of fish...

Comparison of artificial diets for rearing Corcyra cephalonica (Stainton, 1865) (Lep., Pyralidae) for Trichogramma mass production BJB
BERNARDI,E. B.; HADDAD,M. L.; PARRA,J. R. P..
The objective of this research was, based on biological studies, to determine and adequate diet for rearing Corcyra cephalonica (Stainton, 1865) in the laboratory so as to permit the rearing of this factitious host for Trichogramma mass production. The research was conducted at 25 ± 1ºC, RH 60 ± 10% and photophase of 14 hours. Six artificial diets were compared: a) whole wheat flour (48.5%), ground rice (48.5%) and sugar (3%); b) ground rice (97%) and sugar (3%); c) whole wheat flour (48.5%), rice flour (48.5%) an sugar (3%); d) whole wheat flour (97%) and yeast (3%); e) wheat germ (97%) and yeast (3%); f) rice bran (94%), sugar (3%) and yeast (3%); f) rice bran (94%), sugar (3%) and yeast (3%). All of the diets studied permitted the development of C....
