      다국어 초록 (Multilingual Abstract)

      Occurrence of three troublesome lepidopterous pests, Ostrinia furnacalis, Helicoverpa armigera
      and Pseudaletia separata in corn cultivation of the reclaimed land were recorded using sex pheromone
      traps from 2012 to 2014. In case of O. furnacalis adult, two generations were observed in a year and its
      occurrence pattern was very regular. The 1st generation showed the highest occurrence in late May-early
      June and the 2nd generation was in late July-early August. On the other hand, H. armigera occurred at
      least three times a year but its occurrence was somewhat irregular. H. armigera adult showed the highest
      occurrence in mid May, late June, early August, respectively in 2012 but their occurrence patterns of the
      2nd and 3rd generations were varied in 2013 and 2014. In case of P. separata, a few number of adult
      were captured during the survey period, indicating few number of P. separata migrated from China. Based
      on the control effect of O. furnacalis by Etofenprox and Carbofuranin 2012, June 26 treatment showed
      the highest control rate with 96.8% for Etofenprox, 85.8% for Carbofuran, respectively. Late treatment at
      June 19 and June 26 significantly decreased the control rate of O. furnacalis and June 26 treatment
      showed the lowest control rate of 1.9% for Etofenprox. 18.1% for Carbofuran, respectively.
