摘　　要：研究了饲养空间、温度、光照和饲料成分等生态因子对野生型黑腹果蝇发育和繁殖的影响．结果表明：除光照时间外，其他因子对果蝇的生长、繁殖都有明显的影响．果蝇繁殖的子代数量随饲养空间的增大而增加，最适培养温度为25—28℃，饲料中酵母粉最适用量为常规用量的3．4倍，糖含量高或低都不利于果蝇的发育和繁殖．Effects of rearing space, temperature, light, contents of yeast powder and sucrose in the diet on development and reproduction of fruit fly（Drosophila melanogaster）were investigated. The results showed that all these factors except for light time obviously influenced the fly growth and fecundity. The filial generation produced by the fly increased as cultured space increased, suitable temperature for breeding the fly ranged from 25 ℃ to 28 ℃, 34 times the yeast powder as much as routine usual and moderate content of sucrose in the diet were necessary in order to get better rearing effectiveness.
