The 4th instar larvae of the Sa.A strain (the weak race from Sapporo) were used as hosts and those of the Mi.A strain (the neutral (minus) race from Miyazaki) as donors of the transplant. The host larva with the gonads intact received a pair of larval ovaries or testes from the donor. 114 moths (63♂♂: 51♀♀) emerged from 124 ovary-transplanted larvae, and 79 moths (40♂♂: 39♀♀) from 100 testis-transplanted larvae. The results are shown in Table 1 and 2. Careful observations were made on their external sexual characters, such as the color of the compound eyes and wings, the wing-markings, the structure of frenulum, antennae, male genitalia and legs, woolly abdominal hairs of the female, general appearance of the abdomen, and black patterns on the dorsal side of the abdominal segments of the male. The results of observations revealed that neither ovarian nor testicular grafts in larvae did cause the morphological changes in the sexual characters in the adult host.
