The pupa (7th. day after mounting) were irradiated for foully minutes with 1,000-ray and the copulation was done under the various conditions when the pupa grew to be imagos. The silkworm eggs that the imagos laid were divided into many groups by five, fifteen, foully-five, ninety, seven-hundred, twenty and twenty-four hundred minutes eggs respectively and the lipid phosphorus in the each group of eggs was analyzed as follows. 1. The quantity of 928/100mg dry powder (D. P.) was shown in the group of the fourt-five minutes eggs whose ovum nucleus and sperm nucleus were not conjugate in the control C (male and female). The number of the greatest quantity of 944/100mg D.P. after the syngamy of ovum nucleus and sperm nucleus while the smallest quantity was 768/100mg D.P. in the group of ninety minutes eggs. 2. Not much difference could be seen the copulation group of female irradiation and male control and the copulation group of male irradiation and female control compared to the both male and female control group, but the influence could be seen in the group of irradiated female pupas. 3. The great difference could be seen in the group of irradiated male and female pupa compared to the control group. The five minutes eggs showed the smallest quantity of 536/100mg D.P. and the quantity of lipid phosphorus rapidly began to increase from the fifteen minutes eggs. The quantity amounted to 1,082/100 mg D.P. in the case of seven hundred and twenty minutes eggs while the quantity decreased in the twenty-four hundred minutes eggs which showed 912/100 mg D.P. The general result obtained in the present study was that the irradiated male and female pupa were greatly influenced before and after the syngamy of gamete.
