초록

본 연구는 경남 진주에서 여름철에 풀숲에서 아름다운 소리를 들려주는 정서곤충의 한 종류인 여치(Gampsocleis sedakovi abscura Walker)에 관한 생활사를 3년간 (2005~2007)에 조사한 결과이다. 여치는 1년에 1세대 발생하며, 성충의 몸길이는 암컷이 60 mm정도이며 수컷은 50 mm정도이었다. 몸의 색깔은 녹색 또는 암갈색의 두 종류가 있었다. 땅 속에서 알 상태로 월동하며, 야외에서 3월 상순부터 약충을 볼 수 있었으며 성충의 우화 최성기는 7월 상순이었다. 야외에서 알기간이 269일, 약충기간이 88일로 성충이 되기까지 357일이 걸렸다. 3년간 평균 산란기간은 63일이었고, 산란수는 평균 94개였다. 평균수명은 암컷이 90일, 수컷이 82일이었으며, 성비는 암컷이 52%이었다. 일일 중 성충의 우화는 오전 8시에서 10시 사이가 가장 많았다.

Life history of Gampsocleis sedakovi abscura Walker, an amenity sound producing insect, was investigated in Jinju, Korea from 2005 to 2007. G. sedakovi abscura had a generation per year and could be seen in the field from early March to late September. The peak emergence period of adults was early July. Developmental period from egg to adult was 357 days in average of three years in the field. Egg and nymphal periods, and adult longevity were 269, 88, and 357 days in average, respectively. The average ovipositional period was 63 days, and an adult laid 94 eggs in average throughout her life. The average longevity of adult was 90 days for female and 82 days for male. The sex ratio was 52%. G. sedakovi abscura over-wintered as egg stage in the soil. Circadian rhythm of the adult emergence showed that more than 70% of the adults emerged in the morning.
