Surveys were conducted in 66 ginseng fields damaged by insect and other an~mal pests from 1984 to 1993. Holohichio rnoroso, Holotrichio dromphalio, Holotrichia titonis Malodera orientaliq Ectinus sericeus, Gyllotalpa ofricana, Teleog~iluse mmo, Ostrinio furnacoii* Agrotis tokionis, Marnestro brassicae, Hydrellia griseolo, unidentified stem maggo$, Pseudococcus comstocki (13 species of insects). Deroceras uarions (slug), Acusta despecta sieboldiona (snail), probably two species of rats. and pheasant species were ascertained to damage ginseng plants M them, Holotrich~a morosa, Holotrichia diomphalia, Gryliotaipo africanq Deroceras uarions, Acusto despech siebaldiano showed higher frequencies. Underground (root) damage occul~ed mainly in spring penod (MayJune) and fall period (September-Odober) in 2-year-old glnseng fields at slopes, and aboveground (leaf and stem) damage occurred mainly in spring period in 3 or more-year-old ginseng iields mulched with rice straws at plains. Three ginseng fields were abolished due to heavy underground damage.

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 white grubs in turfgrass were investigated from 15 golf clubs in 7 provinces and 2 metropolitan cities. 12 white grub species were collected and 11 species in 8 genera including oriental beetle, Anomala orientalis were identified but 1 species was not identified. The oriental beetle grub was the most serious pest in turfgrass out of them. The brown chafer, Adoretus tenuimaculatus was widely distributed species collected from 6 golf clubs, Maladera castanea was collected from 5 golf clubs and A. orientalis, Holotrichia kiotoensis, and M. orientalis were collected from 4 golf clubs. The white grubs, their density, and distribution depth were also observed at tee, fairway, and green from Yongweon, Daegu, and Dongrae golf clubs. A. orientalis was dominant species in overwintering season but A. tenuimaculatus was dominant one in unoverwintering season. The density of white grubs was low in the green compared with tee or fairway. Distribution depth was different depending on season in Daegu and Dongrae golf clubs but not different in Yongweon golf club. Although there showed no differences in white grub species depending on turfgrass but density was different, that is, A. tenuimaculatus was abundant in Zoysia matrella while A. orientalis abundant in Poa pratensis. The density of A. orientalis grubs was higher in older golf courses but there showed no differences in white grub species depending on the age of golf club.

This experiment was conducted to investigate population dynamics of white grubs and its damages in sweet potato fields. There were three species of white grubs that fed on the roots of sweet potato in Honam area. Among them, Holofrichia parallela was a major insect pest. Damage rate of sweet potato by white grubs were about 2 to 40% differed with regions. In some region where it was severe the damage rate of sweet potato was about 80% or more. H. parallela overwintered as a late 3rd instar larvae in soil from late October to late-June, and the survival rate of them was 92%. The occurrence pattern of H. parallela larvae varied in different seasons. In sweet potato field, H. parallela larvae populations started being observed during late-July to mid.-August. The damage by the grub began to occur late-August in field and lasted to the harvest time.

The efficacy of different control techniques against the large black chafer, Holotrichia parallela Motschulsky (Coleoptera: Scarabaeidae), in organic pear (Pyrus pyrifolia) orchards was evaluated. In this study, field trials were conducted in three locations in Korea-Naju, Hampyeong, and Boseong-to evaluate different techniques to suppress these beetles. Pheromone traps, bio-insecticides (Hongmengye and Melchungdaejang), and a combination of the two were applied as treatments. In Naju, Hampyeong, and Boseong, the highest number of adult H. parallela were caught in the control plots (n=45, n=39, and n=20, respectively), while the fewest were caught in the pheromone plus bio-insecticide plot (n=19) in Naju and in the combined treatment plot in Hampyeong (n=10). In Naju, the greatest leaf damage was observed in the control (66%), and in all locations (Naju, Boseong, and Hampyeong), the least damage occurred in the combined treatment plots (42%, 36%, and 24%, respectively). Regarding the tree canopy, the greatest leaf damage was observed in the upper canopy, and less damage was observed in the lower canopy. These results demonstrate that the combination of sex pheromone traps and bio-insecticides can be used to manage H. parallela in organic pear orchards.

The investigation of the kinds and density of white grubs in relation to soil texture, forages, yearsafter pasture establishment, and management methods in pasture were surveyed in Livestock ExperimentStation, Suwon by digging 5 sites($100cm{\times}100cm$) in a month from April to October during 1985.The results obtained were summarized as follows; No difference was observed in white grub speciesdivesity in relation to soil texture, forages, years after pasture establishment, and management methodof pasture, but the abundance of each species was different from the environmental factors.1. On the soil texture; Miridiba kureana, Popillia uchidai, Holotrichia mmosa and Holotrichia diomphalia occurred in the clay loam field, whereas Anomala corpulenta and Anomala mfocuprea in the sandy loam. 2. On the forage; the density of all species except Popillia uchidai was higher in grass than legume. 3. On the years after pasture extablishment; both of the species diversity and abundance were increased 3 years after pasture establishment and maximized at the 5th year.4. On the management methods of pasture; species diversity and abundance were higher in meadows thanpastures.

Non-chemical or low-chemical control measures against key insect pests and rats in the ginseng field were studied from 1993 through 1999. Broadcasting chemicals beside the ginseng field in the oviposition period showed the same control effect on the adults of the Korean black chafer, Holotrichia diomphalia, as broadcasting at the ginseng ridge. Ginseng damage by adults of African mole cricket, Gryl1ota1pa africana, were reduced considerably by broadcasting chemicals beside the ginseng field. The larvae of wheat wireworm, Ectinus sericeus, were attracted effectively to potatoes in the ginseng field. Spreads of the mealybug, Pseudococcus comstocki, were very slow in the ginseng field, indicating that it is possible to eradicate the early colonies of Pseudococcus comstocki effectively. The rat repeller, Dekur $500S^{showed}$ a significant control effect of rats in the ginseng field.

Densities and larval food habits of Holotrichia titanis belonging to Melolonthinae, and of Anomala corpulenta and A. mfocuprea belonging to Rutelinae, collected from surroundings of ginseng fields, were investigated to determine potentia]s as ginseng pests in scarabaeids. H. titanis had similar food habit to the ginseng pests, H. morosa and H. diomphalia, although the density of H. titanis was relatively low during the period of survey, which indicates that the scarabaeid may have potentials to be a major pest with build-up or the population in the fields. However, A. corpulenta and A. rufacuprea with higher populations than H. morose and H. dicmphalia had no or low potency as ginseng pests since they had little preference to ginseng roots or did not feed on these. The latter two species in Rutelinae showed different food habits in relation to dead organic matter.
