野生黑腹果蝇培养条件的优化试验

Optimization Culture Condition Test of Wild Drosophila Melanogaster

在实验条件下,设计了温度、光照、酵母浸粉、蔗糖比例培养条件,对野生黑腹果蝇发育和繁殖的影响.结果表明:除光照时间外,其他因素对黑腹果蝇的生长、繁殖都有较明显的影响.野生黑腹果蝇最适培养温度为25-28℃,饲料中酵母浸粉最适用量为常规用量0.6 g,糖含量过高或过低都不利于果蝇的发育和繁殖.

In the experimental condition, the influence of temperature, illumination, yeast powder, su- crose culture conditions on wild Drosophila melanogaster developmental and reproductive effects was studied. The results showed that all factors have influence on Drosophila melanogaster growth except the illumination time. The influence of reproduction is more apparent. The suitable culture temperature for wild drosophila melanogaster is 25 ~ 28℃, the most suitable amount of feed yeast powder in conventional dosage is 0.6g. Too high or too low sugar content is detrimental to the development and reproduction of Drosophila melanogaster. Key words： Drosophila melanogaster ; culture condition; life history; optimization test
