摘要

外米綴蛾(Corcyra cephalonica (Stainton))幼蟲以碎粒糙米飼養於30 ± 1°C，70 ± 5% RH，每日06:00開燈，18:00關燈(12L:12D)之生長箱中，觀察成蟲羽化及壽命。結果得知雌、雄蛾每日之羽化時刻集中於12:00～22:00，雄蛾羽化時刻較雌蛾早2～3小時。雄蛾羽化高峰在17:00～19:00，雌蛾在18:00～20:00。羽化之雌、雄蛾單一配對飼養時，83.3%雌蛾生產之子代個體中，雌、雄比依χ^2測驗附合1:1；其餘16.7%之雌蛾生產之子代個體中，雌、雄比大於1或小於1。但在同一族群中，雌、雄蛾個體比例為1:1。已交尾雌、雄蛾的壽命分別為8.1和12.9日，均較未交尾雌、雄者(10.2和16.4日)為短。

Rice moth (Corcyra cephalonica (Stainton) larvae were reared on crushed brown rice in a growth chamber at 30±1°C, 70±5% RH, with a 12L : 12D photoperiod (The light was turned on at 06 : 00 and was off at 18 : 00). Adults emerged from 12 : 00 to 22 : 00 each day. Male moths emerged 2-3 h earlier than the females. The emergence peak took place at 17 : 00-19 : 00 and 18 : 00-20 : 00 for males and females, respectively. Based on X^2 test of goodness of fit, the ratio of females to males was 1 : 1 in the population. of females, 83.3% produced offspring whose ratio of females to males was equal to 1; the rest produced offspring with a ratio greater or less than 1. The mean longevity of mated females and males was 8.1 and 12.9 days respectively; of those unmated it was 10.2 and 16.4 days, respectively.
