- ON THE EXPERIMENTS OF OVARIAN TRANSPLANTATION AND BLOOD TRANSFUSION IN THE SILKWORM, WITH SPECIAL REFERENCE TO THE ALTERATION OF VOLTINISM
抄録
The transplantation of ovaries in the silkworm was performed between univoltine and bivoltine races. The larvae of the forth or fifth age were used for the operation preferably. The materials for the experiment were prepared in view of influences of incubating conditions upon voltinism, such as: by the incubation at a lower temperature (15°C) and with dry air-“cold incubation”, the eggs of univoltine races give rise generally to the moths laying hibernating eggs, while those of bivoltine races present always the moths laying unhibernating eggs; by the incubation at a higher temperature (25°C) and with moist air-“hot incubation”, the eggs of both univoltine and bivoltine races are bred equally to the moths laying hibernating eggs. So the author used in this experiment for univoltine the “hot-incubated” larvae of three bivoltine races (Japanese No. 105, J. No. 7 and J. Bunrikokensyu) and of two univoltine races (European 7 and a cross E. No. 7×J. No. 107); and for bivoltine the “cold-incubated” larvae of three bivoltine races (J. No. 107, Chinese No. 101, and C. Tingyang). The results of the experiment are recorded in the inserted table (I and II) from which the following conclusions may be drawn: the eggs yielded from transplanted ovaries, whatever the sources of the ovaries may be, are of the same nature in voltinism with the eggs laid by the host from its own ovaries, so far as the operation is performed at the later larval stage. (The color of york, being no more than the color of blood, showed naturally direct influence of the host upon transplantated ovaries just as in voltinism. Except these two characters, there could be noticed any character in which the host affected transplanted ovaries directly.)
