Abstract

This study was conducted to investigate the life cycle of Tipula latemarginata Alexander in Korea. The field surveys for the life cycle of the species were carried out at the two sites of Neaseong Stream area in Bongwha County from January 2001 to December 2002. Also many individuals of the species were reared in laboratory to investigate the life cycle. T latemarginata appeared to have three generations a year under the rearing conditions at room temperature. All the processes of life cycle of the species, when reared at room temperature from September 2001 to March 2002, were as follows: Eggs usually hatched between 4 and 10 days after oviposition. First instar larvae grew rapidly and molted to the second instar in 7-9 days. Second instar larvae spent 5-7 days for next molting and third instar period lasted approximately 8-12 days. Fourth instar larvae spent 6 weeks to 5 months for pupation. Especially the duration of fourth instar larval existence was greatly lengthened and served as the overwintering stage. The duration of pupal stage was 6-10 days. In the field, T. latemarginata also appeared to have three generations a year at the favorable habitats.

한국산 애아이노각다귀(Tipula latemarginata Alexander)의 생활사를 조사하기 위하여 2001년 1월부터 2002년 12월까지 봉화군 내성천 유역의 2개 지점에서 야외 실험을 실시하였고, 같은 기간 실험실에서 사육 실험도 병행하였다. 애아이노각다귀는 실험실에서 실온으로 사육하면, 1년에 3세대를 경과하는 것으로 나타났다. 2001년 9월에 산란된 알을 실험실에서 부화시켜 다음 해 3월까지 실온에서 사육했을 때, 이 종의 생활사 전 과정은 다음과 같았다. 알은 산란된 후 보통 $4\~10$일에 부화되었으며, 부화한 유충은 3령기까지는 왕성하게 섭식하며 빠르게 자랐고, 1령 유충 기간은 $7\~9$일, 2령기 $5\~7$일, 3령기 $8\~12$일 정도였으나, 4령기는 6주에서 5개월이 소요되었다. 4령 유충 기간은 월동으로 인해 봄과 여름에 사육할 때 보다 그 기간이 훨씬 길게 나타났다. 용 기간은 $6\~10$일 정도였다. 애아이노각다귀는 야생 상태에서도 서식 환경이 좋은 곳에서는 1년에 3세대를 경과하는 것으로 나타났다.
