Abstract

Agamermis unka, a mermithid parasite of brown planthopper (BPH), Nilaparvata lugens, is the most important natural enemy of BPH and white-backed planthopper (WBPH), Sogatella furcifera in Korea. Distribution of A. unka was investigated in Korean rice fields from 1992 to 1998 and in 2001. Overwintering population of A. unka in Gosung, Namhae, and Tongyoung from 1992 to 1998 was different depending on locality and year. In the survey of A. tanka distribution in the spring of 2001, A. unka was found only at Jangheung and Haenam in Jeonnam province and Namhae, Jinju, Sancheong, Sacheon, Gosung, Tongyoung, Uiryeong, Changwon, Gimhae, and the experimental field of Gyeongsangnamdo Agricultural Research and Extension Services at Jinju in Gyeongnam province out of 30 observed regions in 5 provinces. The number of A. unka was 1,045/㎥ at Namhae, 947/㎥ at the experimental field of Gyeongsangnamdo Agricultural Research and Extension Services, and 395/㎥ at Gosung. Density of A. unka at the rice paddies of Gyeongnam province after harvest in 2001 was higher at the rice fields of Namhae, Gosung, and the experimental field of Gyeongsangnamdo Agricultural Research and Extension Services. Although density of A. unka was higher in the pesticide-untreated plots than fungicide-treated or insecticide-treated plots of forecasting paddies, there were no significant differences. After rice harvest A. unka was found from the forecasting paddies of Gosung, Jinju, Namhae and Sacheon out of 19 observed localities in Gyeongnam province.

벼멸구선충(Agamermis unka)은 우리나라에서 벼멸구와 흰등멸구의 중요한 천적이다. 따라서 1992년부터 1998년까지 그리고 2001년 우리나라의 논에서 벼멸구선충의 분포를 조사하였다. 1992년부터 1998년까지 고성과 경상남도농업기술원, 남해, 통영의 예찰포에서 월동 벼멸구선충의 밀도를 조사한 결과 지역과 연도별로 차이가 있었다. 2001년 5개도 30개 시.군 예찰포를 대상으로 벼멸구선충의 월동 밀도를 조사한 결과, 전남의 장흥과 해남, 경남의 남해, 진주, 산청, 사천, 고성, 통영, 의령, 창원, 김해 지 역에서만 분포가 확인되었다. 그리고 경남 남해지 역 이 1,045마리/㎥로 밀도가 가장 높았고, 진주의 경상남도 농업기술원, 고성 예찰포에서는 각각 947마리와 395마리/㎥가 발견되어 다른 지역의 예찰포보다 높았다. 벼멸구선충의 밀도는 무방제구가 살균제처리나 살충제처리구에 비하여 높았으나 유의성은 없었다. 경남 지역 19개 시군의 예찰포에서 벼 수확 후의 벼멸구선충 밀도를 2001년 가을에 조사한 결과는 고성, 진주, 남해, 사천 지역에서만 분포가 확인되었는데, 밀도는 남해지역이 692마리/㎥로 가장 높았다.
