초록

The potato tuber moth Phthorimaea operculella (Zeller) is an important pest for solanaceous crops mainly potatoes. There is an increasing concern on host expansion to tomato which is higher cash crop. We monitored PTM population dynamics in potato dominated area and tomato greenhouse area in Andon, South Korea for 2 years using delta sticky trap with sex pheromone lure. PTM population was higher in potato growing area and low in tomato area; 19.82 PTM/trap/week and 0.8 PTM/trap/week, respectively. Peak occurrence time was related to the crop phenologies; August in potato field and November in tomato field. Land scape analysis showed that there was significant positive correlation between habitat potato field itself and green house with the number of moth catch during the monitoring period.
