감꼭지나방(나비목: 감꼭지나방과)의 발육과 생식에 미치는 온도의 영향


감꼭지나방의 온도별(15, 20, 25, 3)발육과 생식에 미치는 영향을 조사하였다. 알에서 성충까지의 발육기간은 2에서 96.1일, 에서 43.2일, 3에서 34.6일이 걸렸다. 15에서는 유충기간중 모두 사망하였다. 발육영점온도는 알, 유충, 번데기, 알~성충이 각각 12.2, 13.5, 13.8, 13.4였다. 유효적산온도는 알, 유충, 번데기, 알~성충이 각각 74.0, 331.3, 160.5, 569.9일도 이었다. 부화율, 용화율 및 우화율은 에서 가장 높았다. 산란전 기간과 성충수명은 2에서 12.6일과 29.3일이며, 에서는 3.8일과 8.6일, 3에서 2.5일과 7.0일이었다. 1세대에 요하는 평균기간(T)은 온도가 높아질수록 짧았으며, 순증식률(R )은 2와 3에서 낮았다. 내적자연증가율(r )은 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). It took 96.1 days to grow from egg to adult at 2, 43.2 days at , and 34.6 days at 3. At 15, 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, 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 . 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, 3.8 and 8.6 days at , and 2.5 and 7.0 days at 3, respectively. Mean generation time in days (T) was shorter at higher temperature. Net reproductive rate per generation (R) was lowest at 2. The intrinsic rate of natural increase (r) was highest at as 0.066.
