MORELLI, Renata et al. New protein sources in adults diet for mass-rearing of Anastrepha fraterculus (Diptera:Tephritidae). Braz. arch. biol. technol. [online]. 2012, vol.55, n.6, pp.827-833. ISSN 1516-8913.

The aim of this study was to find alternatives to reduce the cost of mass production of the South American fruit fly (A. fraterculus) by looking for locally available products as protein source in the diet of adults to replace the imported product without changing the quality parameters. Two yeast from a Brazilian company were evaluated. The quality parameters showed that the imported hydrolyzed yeast used in the adult diet could be perfectly replaced by the local products tested, with a reduction of over 80% of the cost of the diet. The quality of the produced insects remained the same and there were improvements in some quality parameters such as the volume of eggs produced, number of adults flying and longevity under the stress.

Palavras-chave : South American fruit fly; yeasts; aminoacids; insect nutrition; quality control.
