  • The black cutworm, Agrotis ipsilon (Hufnagel) is a major insect pest of economic crops including turfgrasses on golf courses. The entomopathogenic nematode, Steinernema carpocapsae GSN1 strain (ScG), a Korean isolate, is an effective biological control agent for soil dwelling and greenhouse insect pests in Korea. In addition, ScG is commercially produced in Korea. We conducted laboratory, greenhouse, and field trials to evaluate efficacy of ScG against black cutworms in turfgrasses. A rate of 63 infective juveniles (Ijs) per larva killed >90% of $3^{rd}$ instars feeding in cups of artificial diet within 3 days. In greenhouse trials against cutworms feeding in pots of turfgrass, efficacy of ScG was higher against $4^{th}$ instars than against $2^{nd}$ instars (90.0 vs 81.2% mortality, respectively, at $2,000Ijs\;pot^{-1}$) in perennial ryegrass, and higher against $3^{rd}$ instars in creeping bentgrass, Agrostis palustris than in zoysiagrass, Zoysia japonica (96.7 vs 52.5% mortality at $100,000Ijs\;m^{-2}$) in pot. The corrected mortality of $4^{th}$ instar was 79.9% at the rate of $100,000Ijs\;m^{-2}$ in the creeping bentgrass in the field. So ScG could be used as biological control agent against black cutworm in turfgrass of golf courses.

  • The black cutworm, Agrotis ipsilon (Hufnagel), damages various cultivated crops and it can also be a serious pest of turfgrass, especially on golf courses. Essential oils have potential as alternative control agents for insect pests. Sixteen essential oils (anise, camphor, cinnamon, citronella, clove, fennel, geranium, lavender, lemongrass, linseed, neem, peppermint, pine, thyme, turpentine and tea saponin) and paraffin oil were assessed in the laboratory, the green house and field trials for their efficacy against black cutworms in turf. Treatment of potted cores of perennial ryegrass turf with anise, cinnamon, neem, paraffin or turpentine reduced black cutworm damage in a greenhouse trial, and in a similar trial, applying neem oil at 4000, 2000 and 1000 ppm resulted in 100, 100 and 64% mortality, respectively, of black cutworms. Weight of survivors at the 1000 ppm rate was 5- fold less than weight of comparably-aged controls. Neem oil (2000 ppm) reduced growth of black cutworms feeding on treated clippings. A high rate of neem oil followed by irrigation (0.1 L of 20000 ppm neem oil with 0.9 L watering/$m^2$) was more effective than a lower concentration (1 L of 2000 ppm neem oil/$m^2$) against $2^{nd}$ and $3^{rd}$ instars in potted turf cores and field plots, respectively. However, not even the aforementioned higher rate effectively controlled $4^{th}$ instars in the field.

  • Turfgrass insect pests were investigated in different turf sod production areas of Korea. Twelve insect pest species of 7 families in 6 orders and one Eriophyidae mite, Aceria zoysiae were collected from turf sod production areas. The zoysiagrass mite was most frequently occurred zoysiagrass sod production areas. Damaged rate by zoysiagrass mite was increased from May to September. Noctuidae (Spodoptera depravata, Agrotis ipsilon and A. segetum) and Pyralidae (Crambus sp.) insect pests in Lepidoptera were attracted in A. ipsilon sex pheromone trap. Eggs and larva of A. ipsilon was the highest occurred August. Zoysiagrass mite and A. ipsilon were main insect pests in turf sod production areas in Korea.

  • Damage and control of cutworms in the tobacco fields were studied during 1998~2000. It was estimated by surveys on cutworm damage that control measures should be taken for 9.0~10.2% of the surveyed fields. However, most of the interviewed growers broadcasted granule insecticides before or during tobacco plant transplantation. The damaging period and cutworm behavior suggested that the most effective control method would be the application of emulsifiable concentrate or wettable powder around the base of tobacco plants in the fields showing more than ca. 2% of damage ratio.

  • Experiments were conducted to study on bionomics and control of cutworms; Agrotis tokionis, A. ipsilon, A. fucosa in Suweon, 1978-1979. A. ipsilon and A. fucosa had two or three generations and A. tokionis had one generation a year. A large number of A. toikonis occured at the end of September, and the major peaks of the first generation of A. tokionis and A. fucosa were in mid-June, the second generation in mid-August, and the third generation was at the end of September. These cutworms laid many eggs on the lower surface of curved downward leaf of Chinese cabbage and the larvae later than 3rd instar began to cut the basal part of stem and then pulled into the soil. A parasite of A. tokionis, a braconid wasp, Meteorus rubens, and two unidentified Ichneumnid wasps were found. Mocap and Volaton gave effective control to the cutworms but Volaton should be applied not to contact with plant.

  • - Turfgrass insect pests and natura.l enemies for biological control were investigated to develop pest management effectively in golf courses at several golf clubs. Twenty eight insect pest species of 10 families in 6 orders were collected from golf courses. The zoysiagrass mite, Eriophyes zoysiae and root-knot nematode, Meloidogyne incognita were also collected from zoysiagrass. White grubs of several scarab beetles and cutworms (Agrotis spp.) damaged seriously at most surveyed golf clubs. In addition, bluegrass webworm (Crambus sp.), Japanese lawngrass cutworm (Spodoptera depravata), scale insects, Tipula sp., and ants (Camponitus japonicus, Formica japonica, and Lasins japonicus) damaged turfgrasses directly or indirectly in golf courses. The entomopathogenic nematodes, Heterorhabditis spp., Steinernema glaseri, and S. longicaudum, entomopathogenic fungi, Beauveria bassiana and Metarhizium anisopliae, and milky disease, Paenibacil/us popil/iae were isolated from white grubs or turfgrass soil as microbial control agents. Besides, dipteran predators, Cophinopoda chinensis, Philonicus albiceps, and Promachus yesonicus and hymenopteran parasitoid, Tiphia sp. were also collected. The P. yesonicus was the most active in golf courses. The root-knot nematode, M. incognita was found from Zoysia japonica, Z. matrella. and Cynodon dactylon.

  • Fruit piercing moths were collected at every other at orchaed(16.5ha) planted with plum, peach and pear, and surrounded by forest in Gyeongnam province from jun to September in 1987. Four black light (BL) traps were lightened to attract the moths from sunset to sunrise and sweep net was also used to catch the moths on fruit and around fruit trees from 22 to 23 o'clock, 20 minutes per fruit tree species. Forty-one species, including 15 primary piercing species(PPS) and 22 secondary piercing species (SPS), from 3 families were collected and identified as fruit piercing moths. Among them, 16 species are newly recorded as fruit piercing moths in Korea. O. emarginata, L. juno, P. stuposa, C. lata and O. excavata were diminant species of PPS, comprising 86.7% of the whole PPS. Dominant species of SPS were A. ipsilon, M. turca, S. retorata, A. livida and T. oldenlandiae, comprising 80.5% of the whole SPS. The ratios of PPS to the whole fruit piercing moths collected by BL traps and net were sweep 15.2% and 79.7%, repectively. By sweep net L. juno, P. stuposa, and O. emarginata was also captured in a large numbers on peach, C. lata was on plum, and S. retorata was on pear.

  • Moths were collected to survey turfgrass pest and to compare species diversity from Jinju Country Club in Jinju, Gyeongsangnamdo, Korea, every 10 days using 200W mercury light trap from middle May to late October in 2008. As the results, only 23 individuals of Pseudaletia separata, Spodoptera depravata, Spodoptera litura, Agrotis segetum, and Agrotis ipsilon were collected as turf grass insect pests. However, 2028 individuals of 388 species in 22 families were collected in total. Dominant species was Culcula panterinaria, Fentonia ocypete, Hypsopygia regina, Culcula panterinaria, Flavocrambus striatellus, and Diarsia camescens in May, June, July, August, September and October, respectively. Species diversity was not different between two surveyed sites, but different among surveyed time. Species richness was more higher in hole 11 (Hole was surrounded by natural forest and located near pond) than hole 15 (Hole was located at the top part of mountain). Dominance index of moth was increased from October compared with diverse index and richness index were decreased from October. A large number of species and individuals were recorded in Noctuidae (502 individuals in 131 species), Geometridae (491 individuals in 84 species), Pyralidae (386 individuals in 73 species), and Notodontidae (277 individuals in 25 species). These four families were 80.9% out of all the collected species.
