摘要

本研究柑橘鳳蝶（Papilio xuthus xuthus Linnaeus）（鱗翅目：鳳蝶科）幼蟲的食葉量。在網室內採集試驗當日產下的柑橘鳳蝶卵粒，置於在25±1℃，80±5%RH，光週期14L：10D條件的恆溫生長箱中，卵孵化後幼蟲以酸橘（Citrus sunki）葉片單隻飼育，試驗結果得知，幼蟲食葉量會隨著齡期增長而增加，幼蟲食葉量以第一齡幼蟲的0.35 cm^2（佔0.23%）為最小，第五齡幼蟲的122.53 cm^2（佔80.38%）為最大，第五齡幼蟲食葉量為第一齡的350倍，幼蟲期的總食葉量平均為152.43 ± 7.11 cm^2。各齡幼蟲的食葉量常用對數隨齡期增長而呈直線迴歸關係增加，且大致隨齡期以0.6076倍呈等比增長。各齡期幼蟲的取食速率以第一齡幼蟲的0.09 cm^2/day最慢，第五齡幼蟲的4.49 cm^2/day最快，取食速率隨齡期增長而增加，且各齡期幼蟲的取食速率常用對數和齡期間呈直線迴歸關係。

This paper studied leaf consumption of each larval instar of Chinese yellow swallowtail, Papilio xuthus xuthus Linnaeus. Eggs of Chinese yellow swallowtail were collected from the host plant in the net house and placed in the growth chamber with conditions of 25 ± 1℃, 80 ± 5% RH, and in a photoperiod of 14 hr light and 10 hr darkness. The newly hatching larvae were individually reared on leaves of Citrus sunki for investigation of larval leaf consumption. Results showed that the increment of larval leaf consumption were in accordance with the increase in larval instar stage. The smallest leaf consumption was 0.35 cm^2 (0.23%) of the first instar larval stage. And the greatest leaf consumption was 122.53 cm^2 (80.38%) which occurred at the fifth instar larval stage. Furthermore, leaf consumption of the fifth instar larva divided by the first instar larva was 350 times. The total leaf areas consumed was 152.43 ± 7.11 cm^2 in average during larval stage. A linear regression relationship was existed between the common logarithms of leaf consumption and the larval instar stages. The increment of the common logarithms of leaf consumption was in accordance with the increase in the larval instar stage, and it maintained a ratio of 0.6076 times. The slowest leaf consumption rate was 0.09 cm^2/day of the first instar larval stage. Relatively, the fastest was 4.49 cm^2/day of the fifth instar larval stage. Leaf consumption rate increased as the larval instar stages grew. A linear regression relationship was existed between the common logarithms of leaf consumption rate and the larval instar stages.
