주홍날개들명나방의 생식과 발육에 미치는 온도의 영향

초록

주홍날개들명나방(Udea ferrugalis)의 온도별(10, 15, 18, 20, 23, 25, 27, 3) 발육과 생식에 미치는 은도영향에 대하여 조사하였다. 난, 유충, 용기간은 고온에서 짧은 경향이었고, 1에서는 난과 용 발육은 완료되지 않았다. 각 태별 발육영접온도는 난이 9.5, 유충 9.6 그리고 용은 11.9이었고, 유효적산온도는 각각 87.9, 200.9, 119.7일도이었다. 산란전기간과 성충수명은 15에서 10.9일, 25.2일이었으나, 23에서는 2.5일, 7.3일, 3에서는 1.7일, 5.3일로써 온도가 높아질수록 그 기간이 짧았다. 평균산란수는 2와 23에서 가장 많았다. 세대당 순증식율은 (Ro) 2에서 265.4로써 가장 높았고, 내적자연증가율은(r ) 에서 0.247로 가장 높았다. 이 결과로써 주흥날개들명나방의 발육과 생식에 적합한 온도는 2에서 23이었다.

Abstract

Effects of temperature on the development and reproduction of the Udea ferrugalis Hubner were investigated at various temperatures (10, 15, 18, 20, 23, 25, 27, 30). The development times of eggs, larvae, prepupae and pupae were shorter in higher temperatures than in lower ones. Egg and pupa did not develop at 10. The lower developmental threshold temperatures for eggs, larvae, pupae were 9.5, 9.6 and 11.9, respectively, and their thermal requirements for development completion were 87.9, 200.9 and 119.7 degree-days at the same temperature, respectively. Adult longevity was 25.2 days at 15, 7.3 at 23 and 5.3 at 30. Mean fecundity per female was higher at 20-23 compared to other temperatures. Mean generation time in days (T) was shorter in higher temperature region. Net reproductive rate per generation (Ro) was lowest at 15 (138.2) and it was highest at 20 (265.4). The intrinsic rate of natural increase (rm/) was highest at 25 as 0.247. As a result, it was considered that optimum range of temperature for U. ferrugalis growth was 20.0 to 23.
