This study was conducted to investigate the life cycle of Kunugia yamadai Nagano attacking Qriercrrs spp. in Chungju area, Korea during 1987-1989. The moth had one generation a year. Host plants of the species were Quercus acutissima, Q. serrata, Q. aliena, and Castanea crenata. And Q. dentata T., and Q variahilis B. were newly recognized as host plants of the insect. Young larvae were hatched from the overwintered eggs and fed on the leaves from late April to early August which took ahout 3 months. In mid-August, the fully grown larva made a rough cocoon and pupated at the ground debris or dense grass. The moths emerged from September to late October with a peak around mid-October. Female oviposited 121 eggs on average mostly on the bark of host plants at 131 cm ahove the ground.

This study was carried out to investigate the life history of Paralebeda plagifera femorata in 1998 and 1999. Ginkgo biloba was newly known to be a host plant for the species in this study. The moth has one generation a year. It overwinted as 6th instar larva on branches of the host plant. The 9th instar larva made a rough cocoon by webbing two or three leaves, and pupated on the branch on late June. The moths emerged from early July through early August with a peak around late July. A female oviposited 205 eggs on an average on the branch, twig, or leaf margin.

The developing ovarian oocyte of Dendrolimus spectabilis has been studied by using electron microscopical techniques. After yolk formation the vitelline membrane was laid down in the intercellular space between the follicle cell and the oocyte. But before the vitelline membrane formation the granules with high electron density that the vitelline membrane precusor are observed in the follicle cell. At the late vitellogenesis stage these granules were transported into the intercellular space between the follicle cells and the oocyte. These granules fuse to each other and larger bodies which eventually produce the vitelline membrane. The vitelline membrane was distinguished into the light inner and dark outer membrane. Next the chorion was laid down. It was apparent that the chorion was laid down in the intercellular space immediately adjacent to the vitelline membrane, and that it was formed by the follicle cells only.

Wild silkmoths can be utilised sustainably in the production of silk as an income for resource-poor rural communities. However, attack by parasitoids and predators affect the quality of cocoons and quantity of raw silk produced. A laboratory experiment was undertaken to quantify the effect of parasitoids' (dipteran and hymenopteran) and predators' (ants) exit and ingress holes, respectively, on silk production. The mean number of shells required to produce fifty grams of raw silk was highest with cocoons parasitised by a dipteran and lowest with unattacked cocoons (but with moths already emerged). Degumming loss was highest in parasitised and lowest in unttacked cocoons, but both were not different from cocoons predated by ants. Shell weight was highest in unattacked cocoons, followed by hymenopteran-parasitised and predated cocoons, with the dipteran parasitized ones being the least. Single cocoon weight was greater in hymenopteran-parasitised and predated cocoons than the dipteran-parasitised and unattacked cocoons. Shell ratio or raw silk, floss and yarn weights were higher in unattacked than parasitised and predated cocoons. The total loss in raw silk attributable to attack by parasitoids and predators ranged between 17.4~31.2%. The results offer baseline information for assessment of economic losses in wild silk farming due to parasitoids and predators in the field.
