Abstract

Atualmente são crescentes as publicações apontando a composição da dieta como um fator que pode afetar o tempo de vida e o envelhecimento dos seres vivos, no entanto ainda não são claras as relações entre proporções adequadas de macronutrientes na dieta. O objetivo principal desse estudo foi validar em nosso laboratório o método Continuos Liquid Feeding (CLF) para alimentação de Drosophila melanogaster e verificar como diferentes concentrações de macronutrientes afetam o tempo de vida do inseto. Desenvolvemos os aparatos para CLF, aplicamos dietas com diferentes concentrações de carboidrato: proteína e avaliamos seus efeitos na longevidade e resistência ao frio e fome. Tomados em conjunto nossos dados sugerem que interações metabólicas associadas ao aumento no consumo de açúcar por Drosophila melanogaster afetam sua capacidade de sobreviver em condições críticas.
