紫外线对黑尾果蝇的生物学效应

野生型黑尾果蝇经紫外线连续处理3代，随着照射时间延长，每代均表现显著的生物学效应。这些生物学效应主要是子代数量减少，羽化延续时间缩短，体重减轻，而且有致略效应和间接的诱变效应。但处理后的子代性别比例变化不大。

Biological effects of ultraviolet on Drosophila melanogaster Meigen

Each generation of the wild type Drosophila melanogaster Meigen continually treated showed remarkable biological effects with treated time to be cxtended. These effects were showed mainly in the following aspects: decreasc of progeny, shortenees of emergence time, reduction of weight, malformation and indirectly induced mutation. But the sexual proportion of progeny doesn't change too much after treatment.
