  • When paprika is cultivated during summer season, thrips starts to occur in the early growing season and reaches its peak in late June. In the treatment using Orius laevigatus and Neoseiulus cucumeris, natural enemies to thrips, thrips density was 87.6/trap and 51.3/trap on June 23. After Orius laevigatus and Neoseiulus cucumeris were treated twice on June 24 and July 23, the number decreased considerably. On August 23, it was 36.9/trap and 40.3/trap and from the mid August to early September thrips density remained low. Effect of Orius laevigatus and Neoseiulus cucumeris on suppression of thrips density was 35.7% and 44.6% on July 22, however, the number went up to 88.8% and 80.5% on September 3.

  • 시설과채류(오이, 착색단고추, 토마토, 가지, 참외)의 잎 절편에서 지중해이리응애, 나팔이리응애, 오이이리응애, 사막이리응애를 대상으로 담배가루이 알에 대한 포식능력과 산란능력을 비교 평가하였다. 지중해이리응애의 일평균 담배가루이 알 포식량이 $9{\sim}12$개로 가장 많았으며, 나팔이리응애, 오이이리응애, 사막이리응애가 각각 $6{\sim}9$개, $4{\sim}6$개, $1{\sim}4$개로 뒤를 이었다. 일평균 산란수도 지중해이리응애가 $1.2{\sim}1.9$개로 가장 많았으며, 다른 포식응애들은 0.5개를 넘지 않았다.
