Detrimental effect of rutin on Anticarsia gemmatalis PAB
Hoffmann-Campo,Clara Beatriz; Ramos Neto,José Augusto; Oliveira,Maria Cristina Neves de; Oliveira,Lenita Jacob.
Behavioral and nutritional effect of rutin (quercetin 3-O-rutinosídeo) on Anticarsia gemmatalis Hübner (Lep.: Noctuidae), a major soybean defoliator in Brazil, was evaluated from the third instar to pupation. Rutin is one of the flavonol glycosides identified in the leaves of the wild soybean PI 227687. Larval weight and amount of ingested food decreased as rutin concentration in the diet increase. An interactive effect between feeding time and diet (treatment) was observed on insect growth; when larvae fed on pure-diet, feeding time elongation resulted in heavier pupae. Differently, the weight of larvae fed on rutin-diet remained almost stable, in spite of eating for longer. A. gemmatalis growth was negatively influenced by rutin-diet not only by feeding...

New protein sources in adults diet for mass-rearing of Anastrepha fraterculus (Diptera:Tephritidae) BABT
Morelli,Renata; Costa,Karen Zamboni; Fagioni,Kenya Martins; Costa,Maria de Lourdes Zamboni; Nascimento,Antônio Souza do; Pimentel,Rodrigo Meirelles de Azevedo; Walder,Julio Marcos Melges.
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.
