감꼭지나방(나비목: 감꼭지나방과)의 발육과 생식에 미치는 온도의 영향 = Effect of Temperature on Development and Reproduction of the Persimmon Fruit Moth, Stathmopoda masinissa (Lepidoptera: Stathmopodidae)

국문 초록 (Abstract)

감꼭지나방의 온도별(15, 20, 25, 3$0^{\circ}C$)발육과 생식에 미치는 영향을 조사하였다. 알에서 성충까지의 발육기간은 2$0^{\circ}C$에서 96.1일, $25^{\circ}C$에서 43.2일, 3$0^{\circ}C$에서 34.6일이 걸렸다. 15$^{\circ}C$에서는 유충기간중 모두 사망하였다. 발육영점온도는 알, 유충, 번데기, 알~성충이 각각 12.2, 13.5, 13.8, 13.4$^{\circ}C$였다. 유효적산온도는 알, 유충, 번데기, 알~성충이 각각 74.0, 331.3, 160.5, 569.9일도 이었다. 부화율, 용화율 및 우화율은 $25^{\circ}C$에서 가장 높았다. 산란전 기간과 성충수명은 2$0^{\circ}C$에서 12.6일과 29.3일이며, $25^{\circ}C$에서는 3.8일과 8.6일, 3$0^{\circ}C$에서 2.5일과 7.0일이었다. 1세대에 요하는 평균기간(T)은 온도가 높아질수록 짧았으며, 순증식률(R$_{o}$ )은 2$0^{\circ}C$와 3$0^{\circ}C$에서 낮았다. 내적자연증가율(r$_{m}$ )은 $25^{\circ}C$에서 0.066로 가장 크게 나타내었다.

Development and reproduction of the persimmon fruit moth, Stathmopoda masinissa, were investigated under different temperatures (15, 20, 25, and 3$0^{\circ}C$). It took 96.1 days to grow from egg to adult at 2$0^{\circ}C$, 43.2 days at $25^{\circ}C$, and 34.6 days at 3$0^{\circ}C$. At 15$^{\circ}C$, all tested individuals died before pupation. The developmental threshold temperatures for egg, larva, pupa, and adult were 12.2, 13.5, 13.8, and 13.4$^{\circ}C$, respectively. The total effective temperatures for egg, larva, pupa, and egg to adult were 74.0, 331.3, 160.5, and 569.9 degree days, respectively. The hatching, pupation, and emergence rates were highest at $25^{\circ}C$. The average life span of adult prior to laying eggs and the total life span of adult were 12.6 and 29.3 days at 2$0^{\circ}C$, 3.8 and 8.6 days at $25^{\circ}C$, and 2.5 and 7.0 days at 3$0^{\circ}C$, respectively. Mean generation time in days (T) was shorter at higher temperature. Net reproductive rate per generation (R$_{o}$) was lowest at 2$0^{\circ}C$. The intrinsic rate of natural increase (r$_{m}$) was highest at $25^{\circ}C$ as 0.066.
