영문 초록

This study was conducted to monitor the major pests occurring in organic tea fields and evaluate eco-friendly insecticidal agricultural materials. Eleven species of insect pests were identified over 2 year study period (2015-2016) in Boseong. Tetranychus kanzawai, Eriophyes chibaensis, Calacarus carinatus and Polyphagotarsonemus latus showed the highest peaks from April to June and after late-August. Therefore, management tactics are required in early-April and late-August. Toxoptera aurantii showed the highest peak in early-June and early-September. The major pests among them were Apolygus spinolae (Meyer-Dur) and Caloptilia theivora. High densities of A. spinolae and C. theivora were observed in May and in October, respectively. Moreover, the rates of leaf damage were 28.4% and 10.4%, respectively. The seasonal occurrence of C. theivora was monitored by using a sex pheromone trap, which revealed that C. theivora occurred six times a year from mid-April to mid-December. The peak occurrence of C. theivora was recorded in late September. The controlling effects of OAM containing sophora, neem, a mixture of sophora and neem against four pests (Tetranychus kanzawai, Eriophyes chibaensis, Calacarus carinatus, and Toxoptera aurantii) were more than 94%.
