The aim of this study was to clarify the origins of grubs which were used in the experiments, and to determine many other effects that are now written in the classical medical and herbal books. We compared the efficacy of grubs written in the herbal and medical books on the one hand, and studied the origins of grubs used in the experiments, on the other hand. The following results were obtained. There are three kinds of grub species for medicinal uses. Holorichia diomphalia Bates mainly produced in China, Cetoniidae species mainly produced in Korea, and Protaeria brevitarsis in Korean folk remedy are three species. Grubs were used in 25 experiments. Of these experiments, Holotrichia diomphalia were used 12 times, Larve of Protaeria brevitarsis 3 times, and Protaetia orientalis was used once. So, of total 25 experiments, 36%(9 experiments) did not clarify the origins of grubs used in the experiments. Currently, the grubs, which are imported from China and used in Korea, are Holotrichia diomphalia Bates from China. Current experimental study shows that grubs have efficacy for protecting liver. So the use of grubs in folk medicine is believed to be based on the scientific evidence. Efficacy of grubs, though it is not recorded in the medical books, has the effects of anti-cancer(anti-tumor), antioxidant, and anti-diabetes mellitus. The ingredients of Holotrichia are protein, peptide, fat, enzyme, mineral, and other several nutrients. Study on the grubs so far has a tendency to be done with little focus on the differen of origin of grubs. So, from now on, it needs that the origin of grubs be clarified, and the study on the efficacy from each origin be done. Considering the effects that the classical herbal books have recorded, it is necessary that more profound study proceed to prevent and treat diseases on eyes and ears, on the basis of the fact that grub has multiple ingredients to replenish the vital essence.

The seasonal movements of Holotrichia morosa and H. diomphalia in soil were investigated during the period from 1984 to 1986 in Suwon. Most cf the eggs, active larvae and adults of the two species could be found at the soil depth of I-IDem. The larvae began downward movement in late October and early November in order for overwintering when soil tempe¬rature at 5cm below ground reached about $10^{\circ}C$. The overwintering depths of the larvae were 10-40cm for H. morosa and 30-80cm for H. diomPhalia. After the overwintering, pupation and adult emergence of H. morosa occurred at the overwintered sites, \vhereas H. diomPhalia larvae returned to near soil surface next April, and resumed feeding. H.diomphalia larvae began to move downward again in late June for pupation and adult emergence, and overwintered thereafter as adults at the depth of 1O-40cm.
