通常用作老年学实验材料的是黑腹果蝇(Drosophila melanogaste)。用果蝇作模型有许多优点。 在以果蝇作老年学研究的动物模型的实验中,饲料是一极其重要的基本因素。因为,饲料中的成分影响果蝇的生长、发育和衰老速度从而也影响其寿命;饲料用的某些成分在某些条件下会干扰抗衰老药物作用的发挥。常用的果蝇人工饲料主要有以活酵母为主和不含活酵母两类。自然界中的果蝇喜食腐烂水果上的活酵母。
The commonly used gerontology experimental material is Drosophila melanogaste. There are many advantages to using the fruit fly as a model. In experiments with fruit flies as an animal model for gerontology, feed was an extremely important basic factor. Because the ingredients in feed affect the speed of growth, development, and aging of fruit flies and thus their lifespan; certain ingredients used in feeds can interfere with the effects of anti-aging drugs under certain conditions. Commonly used fruit fly artificial diets mainly live yeast and live yeast two categories. Drosophila in nature eats live yeast on rotted fruits.
