  • Insect pests have been one of the main constraints affecting turf sod cultivation areas, playgrounds, parks, golf courses, airports and other related recreational grounds. However, turfgrass research has been very limited and confined within a limited period of time compared to other branches of crop science in Korea. This review was surveyed from all papers in KCI (Korea Citation Index), SCI (Scientific Citation Index) and SCIE (SCI Expended) journals related to turfgrass research in Korea. Fifty two papers concerning turfgrass insect pest in Korea have hitherto been published in 8 different scientific journals since 1990. Thirty three papers (63.5% of total) were published in Weed and Turfgrass Science. The main topics of focus were divided into two parts; ecological study and control of insect pests. Before the 1990 decade, there were no scientific papers published in relation to turfgrass insect pest science. However, during the 1990, 2000 and 2010 decades, 9, 10 and 14 papers were published respectively in Weed and Turfgrass Science. From 1997, about 2 papers were published per year in the scientific journals. Thirty three insect pest species belonging to 13 families in 6 orders, one Eriophyidae mite, Aceria zoysia and one Armadillidae sowbug, Armadillidium vulgare, have hitherto been listed as turfgrass arthropod pests in Korea. Fifty percent of turfgrass insect pest papers published were focused on whitegrub, Adoretus tenuimaculatus, Popillia quadrigutta and earthworm research in Korea.

  • The oriental beetle, Exomala orientalis, Is the most important insect pest of turfgrass in Korean golf courses. The study was carried out to get practical information on the sampling of E. orientalis in golf courses. Real numbers of E. orientalis larvae were compared with and observed numbers depending on sampling size (5$\times$5 cm, l0$\times$10 cm, 20$\times$20 cm, 30$\times$30 cm, and 40$\times$40 cm) and times (3 to 15 replicates) in Dongrae Benest Golf Club. Over 95% accuracy was obtained between real data and estimated data at the density of over 303 larvae/m$^2$ when the 20$\times$20 cm was sampled with 4 replications. Larval density of E. orientalis was different depending on year and course sites (tee, fairway, rough, green).

  • White grub damages various crops, trees and they can also be one of the most serious pests of turf grass in golf courses. This study was conducted to determine the biocontrol of white grubs with 18 different kinds (anise, camphor, castor, cinnamon, clove oil, citronella, fennel, geranium, lavender, lemongrass, linseed, neem, peppermint, pine, rosemary, tea-tree, thyme, and turpentine) of plant essential oils in laboratory, green house and field. Anise oil (88.9%), linseed oil (100%), and tea-tree oil (88.9%) were highly effective among tested essential oils against 3rd instar of Bifurcanmala aulax in cap vial experiment. However, anise and linseed oils showed low mortality against $3^{rd}$ instar of Popillia japonica in pot greenhouse experiment. Efficacy of anise, linseed oil, and tea-tree was also different depending on target white grub in field trials. Correlated mortality showed 32.6% only in tea-tree oil treatment against pupae of Adoretus tenuimaculatus however, correlated mortality of anise, linseed and tea-tree oil were 54.8, 51.6 and 56.5% respectively against $3^{rd}$ instar of Exomala orientalis in the field trial in Adelscott Country Club in Hapcheon, Gyeongnam province.
