　　Objective: To study the addition of L-arginine to corn agar medium, and to study the effect of L-arginine on the pupation time, appearance time, appearance rate and male-male ratio of Drosophila. Method: The experiment is divided into two groups, a control group and an experimental group. The control group is a basal medium. In the experimental group, 1?-arginine was added to the basic medium. There are 7 pairs of fruits in each tube. The flies are placed in a ratio of 1:1 to male and female. There are 12 copies in each group. After 72 hours of inoculation, the parents were taken out, and the pupation time, appearance time, number of appearances, and number of males and females were displayed respectively.

　　Results: The number of 1?-arginine pupae and the appearance of white eyes (w1118), residual feathers (CyO) and wild-type Drosophila melanogaster increased by 313.64?303.53? (Pu003c0.01) and 157.09 182.76? After Pu003c0.01)) and 233.33? Add 239.03?u003c0.01) and 1? Arginine, is the pupation time of white eyes and wild-type fruit flies 2 days earlier than the control group?

　　Conclusion: Under the experimental conditions, 1 L-arginine can improve the fertility of experimental fruit flies, but can it be applied to the amplification of experimental fruit flies?
