Scarabaeids and white grubs were investigated at Halla arboretum and nursery in Jeju province in 1999 and 2001. Scarabaeid pests were surveyed from 14 tree species of 12 families at Halla arboretum in Jeju in March, 1999 and from 55 species of 27 families in March and September, 2001 and from Taxus cuspidata at nursery in Seoguipo in March, 1999 and 18 tree species of 9 families at the same nursery in March and September, 2001. Six species of white grubs and scarabaeids were collected from Halla arboretum. At Halla arboretum, Holotrichia niponensis was collected from 28 tree species of 21 families, H. diomphalia from 27 tree species of 20 families, and an unidentified white grub from 27 tree species of 19 families. Maladera orientalis was collected from 4 tree species of 4 families and Aphodius sp. and Adoretus tenuimaculatus from Punica granatum and Carpinus sieboldiana. At Halla nursery in Seoguipo, H. niponensis were collected from 9 tree species of 6 families and H. diomphalia from 10 tree species of 6 families. White grub of Minela testaceopes was collected from Ternsstraemia japonica. H. niponensis, H. diomphalia and an unidentified white grub were dominant species out of collected white grubs and scarabaeids and these were collected from Cinamomum camphrora. H. niponensis was the most serious pest on T. cuspidata.

The white grubs were collected from ginseng field and fallow lands to examine their external morphology and species components. They were divided into 3 subfamilies, i.e., Melolonthinae, Rutellinae, and Sericinae by the shape of anal slit and/or presence of elevated lines in stridulating area of mandible. Eight species were identified by means of comparing the shape of anal slit, setal arrangement of decasternite, and frontoepicranial series of setae. Larvae of Holotrichia diomphalia and H. morosa were observed to damage ginseng root in field.

Phytophagous insects of Monocotyledoneae were surveyed from May to October in 1991. Each p province was divided into 9 localities by $\boxplus$-shape for the collection. Seventeen weed species b belonging to 17 genera were collected, namely, 14 Graminales weed species of 14 genera, 1 s species of Farinales weed, and 1 species of Liliales weed. Phytophagous insects representing 5 orders, 13 families, 27 genera, and 36 species comprised the insect fauna on Monocotyledoneae w weeds. Five species were not identified out of 36 insect species. Grasshoppers, hemipteran, s scarab beetles, and leaf beetles were frequently collected. Lema concinnipennis was a potential biological agent on Commelina communis, and Oulema dilutipes was first collected from Setaria u viridis. Commelina communis in golf course was severely damaged by Adoretus tenuimacu/atus c chafer but this insect was also an important insect pest of turfgrass and trees.

Species and seasonal occurrences of Sencinae, Melolonthinae and Rutelinae chafers captured b by blacklight traps were investigated from 1989 to 1991 in Suwon and Chonju. Numbers of s species captured in Suwon and Chonju were 6 and 6 for Sericinae, 8 and 7 for Melolothinae, 7 a and 8 for Rutelinae, 21 and 21 in total, respectively. Species with more captures from both districts in each subfamily were Maladera orientalis of Sericinae, Holotrichia morosa and H. diomphalia of Melolonthinae, and Anomala corpulenta, and A. rufocuprea of Rutelinae. Adults of t the above five species were captured 1O~20 days earlier in Chonju than in Suwon. H. d diomphalia adults occurred mamly In odd years in Chonju, which is the same pattern as in S Suwon.

Korean entomopathogenic nematode strain were evaluated against white grubs, Popillia quadriguttata, Ectinohoplia rufipes and Phyllopertha diversa in laboratory. In addition we examined the efficacy of entomopatogenic nematode, Heterorhabditis sp. KCTC 0991BP strain against white grubs in Seaside Golf Club in Gimpo, Gyeonggii and persistence of entomopatogenic nematode in fairway of Anyang Benest Golf Club in Gunpo, Gyeonggii. In laboratory Heterorhabditis bacteriophora Hamyang strain showed 95% mortality against Popillia quadriguttata. H. bacteriophora Hamyang strain and Heterorhabditis sp. KCTC 0991BP induced 80% mortality against 3rd instar of Ectinohoplia rufipes. However, the letter showed only 60% mortality against Phyllopertha diversa. White grub density was reduced to 39% by the application of Heterorhabditis sp. KCTC 0991BP at the rate of $2.24{\times}10^9$ infective juveniles $ha^{-1}$ compared with control in Seaside Golf Club. Heterorhabditis sp. KCTC 0991BP persisted for two months at $5{\sim}10$ cm soil depth but not persisted at $0{\sim}5$ cm soil depth for the same periods when applied at the rate of $2.47{\times}10^9$ infective juveniles $ha^{-1}$.

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.
