Damage of Grapevines by Apolygus spinolae (Hemiptera : Miridae) in Grape Export Complex Area in Korea

다국어 초록 (Multilingual Abstract)

The green pale plant bug, Apolygus spinolae was one of the main insect pests that damaged leaves and fruit in grapes and its damage status was firstly reported in 2000 in grape orchards. This research was conducted to evaluate the distribution and difference in damage rate depending in management type of grapevine orchards (domestic sale farm vs export farm) in the export complex area of Korea (Hwangsung in Gyeonggii, Sangju and Yeongcheon in Gyeongbuk, Namwon in Junbuk and Yeongdong in Chungbuk) from 2010 to 2012. Damage by A. spinolae occurred in all 62 survey farms and damage rate differed depending on locality and individual farms in the same area. Damage rate was lower in export farms than in domestic sale farms, and damage rate of leaves was highly correlated with damage rate of new shoots. 15 species of hemipteran insect were attracted to sticky traps and A. spinolae was the dominant species. The attracted number of A. spinolae in the sticky traps differed depending on locality, and more occurred in domestic sale farms than expert farms. A. spinolae was continually attracted to sticky traps in the harvest period in grapevine orchards.
