This study provides basic information on morphological characteristics of zoysia mite, Aceria zoysiae and symptom in zoysiagrass for turfgrass management in golf courses. Zoysiagrass mite distributed from Pocheon, Gyeonggii province to Jinju, Gyeongnam province and damaged turfgrasses from spring to fall. Damaged leaf by zoysiagrass mite was rolled unidirectionally and mite damaged leaves in the inside of rolled part. Leaves was turned to yellow and damaged area formed irregular yellow patch.

Zoysiagrass mite, Aceria zoysiae is one of the main turfgrass pests causing significant damage on zoysiagrass. In this study we investigated damage by zoysiagrass mite for the selection of zoysiagrass mite-resistance turfgrass individual in natural collected turfgrass isolates transplanted in genetic resources conservation area. In the results of investigation of 295 turfgrass isolates collected from Korea, damage level was different depending on turfgrass species and individuals. Zoysia japonica was highly damaged representing 97.6%, followed by hybrid zoysia and Z. sinica with damage percentages of 87.7% and 81.1% respectively. Additionally, 2 individuals of Z. macrostachya were also damaged by zoysiagrass mite. However several individuals were not damaged by zoysiagrass mite in green house and field. Damage by zoysiagrass mite was occurred from May and peak at after July in field. The study highlighted some important resistant turfgrass individuals which can be used in the management of zoysiagrass mite.

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.
