中文摘要 | 在蝴蝶館中已立足之紫蛇目蝶(Elymnias hypermnestra hainana Lenne)於 氣溫回昇後開始繁殖,惟當其族群密度達到高峰後會將館中之寄主植物啃食殆盡,引起館中 之族群動態呈現頗大之波動,影響展示效果之持續,並破壞展示場所之景觀,因此將繁殖場 所及展示場所隔離是較理想的經營對策。開放時間內紫蛇目蝶吸食鳳梨汁液之日週性對展示 效果影響不大,是極易展示之行為,值得開發為展示題材。本研究並在 25 ± 1 ℃,85 ± 5% 及 12 小時光照條件下以觀音棕竹 (Rhapis excelsa) 飼育紫蛇目蝶,結果卵期為 5.39 ± 0.55 天; 第 1-5 齡幼蟲之發育齡期分別為 4.03 ± 0.82, 3.42 ± 0.75, 4.06 ± 0.62,3.97 ± 0.69 及 6.13 ± 1.13 天;蛹期為 8.03 ± 0.31 天; 從卵到羽化之總發 育期為 35.16 ± 2.03 天。 盛產期之蛹可以 20 ℃之低溫來延後其羽化時間;水分對成蝶 壽命影響極大,上述特性均可做為館中調整此蝶族群參考;本本同時記錄卵之大小,各齡幼 蟲頭殼寬及雌雄蝶之翅長、體長等數據。 |
英文摘要 | The Linneaus common palmfly Elymnias hypermnestra hainana Linne are attracted by rotten fruit for fermented solutions, this sucking behavior is a worthwhile good topic for educational display. We had esablished the population of this butterfly in our aviary since 1989. In the year of 1990, the population density reached the maximum in summer. There were about 100 individ- uals can be observed per day from June to July. Soon, they consumed the hostplant Rhapis excelsa planted inside the aviary as fig. I and the population density sloped down. The popu- lation dynamic presented a dramatic fluctuation. Because we can't keep the display level and the landscape, therefore, the commendable management shall be isolated the breeding site from display site. Eggs collected from the aviary were set in the growth chamber with 25 ± 1 ℃,85、5%RH, LD12:12 photoperiod, and hatching larvae were reared with the leaves of Rhapis exclsa. The results indicated that duration for egg stage was 5.39 ± 0.55 days. The duration of five larval instars were 4.03 ± 0.82, 3.42 ± 0.75, 4.06 ± 0.62, 3.97 ± 0.69 and 6.13 ± 1.13days respectively. The pupal stage took 8.03 ± 0.31 days. It took 35.16 ± 2.03 days to complete one generation. According to this research pupae keep at 20 ℃, took 17.00 ± 0.98 days for emergence, the sur- vival rate was 90%. Water was an important factor the longevity of adults. Character list could be applied to regulated the population dynamic. |
