中文摘要 | 本試驗擬探討青紋細蟌雌雄成蟲體色多樣化與交配行為之相關性。以標記雄成蟲方法探討雄成蟲密度與連結交尾時間之相關性,利用ANOVA檢定,結果顯示不同雄蟲密度之交尾時間並無差異 (F5,114 = 1.318, P > 0.05)。雌成蟲各色型繁殖策略中,雌橘型個體以最多的數量出現 (61.06%),但是只有0.5171比率的個體可以獲得交尾機會,而獲得交尾的個體其交尾次數中等 (5.36次);雌綠型和雄綠型的策略則是以18.25及18.59% 比例出現,但是獲得交尾比例為最高 (0.654及0.660),而可交尾個體平均交尾次數卻又最低 (4.676及4.086次);雄藍型的策略則是出現數量比例最低 (2.10%),而獲得交尾的個體比例也最低 (0.375),卻是有著最多的交尾次數 (7.333次)。 |
英文摘要 | The aim of this study was to investigate the relationship of polychromatism in adult Ischnura senegalensis and their reproductive strategy. Male adults were marked to investigate the relationship among male density, tandem and coupling duration. Male density did not affect the copulation duration. ANOVA was used to test copulation duration among different classes. The result did not detect a significant difference (F5, 114 = 1.318, P > 0.05). Four female color patterns exerted different reproductive strategy. The Female-Orange type had the largest population (61.06%), and only 0.5171 of them had the chance to copulate. However, those individuals that did copulate have a medium number of times (5.36). The Female-Green and Male-Green type were the second highest population (18.25 and 18.59%). They had the highest ratio of copulating (0.654 and 0.660), but their numbers of copulating times were the lowest (4.676 and 4.086). The Male-Blue type had the lowest abundance (2.10%) and the lowest copulation ratio (0.375), but their numbers of copulating times were the highest (7.333). |
