中文摘要 | 於四種不同溫度下,研究偽菜蚜(Lipaphis erysimi(Kalt.))在白蘿蔔(Raphanus sativus L.)上之生活史。結果顯示若蚜發育速率明顯隨溫度上升而加快,以15℃下之10.8天為最長,28℃之6.1天為最短;成蚜壽命以25℃之8.9天為最長,28℃之7.5天為最短;生殖率以28℃之44.8隻子代/♀為最大,15℃之20.4隻子代/♀為最小。以兩性生命表分析數據,內在增殖率(r)及終極增殖率(λ)皆以28℃下者為最大(r = 0.4020/天、λ= 1.4947/天),15℃下最小(r = 0.1706/天、λ= 1.1860/天)。淨增殖率(R_0)也以28℃下最大(R_0 = 40.19子代/♀),20℃下最小(R_0= 12.57子代/♀);粗繁殖率(GRR)以25℃下最大(GRR = 83.96子代),15℃下最小(GRR = 60.98子代);平均世代時間(T)隨溫度之升高而縮短,以15℃下最長(T = 15.49/天),28℃下最短(T = 9.19/天)。若蚜發育臨界低溫(T_0)為-1.2℃,總積溫(K)為176.7日度。族群之存活率、繁殖率、期望壽命、穩定日齡齡期分布與繁殖值也將在本文討論。 |
英文摘要 | The developmental durations of nymphal stages of the turnip aphid, Lipaphis erysimi (Kalt.), at various constant temperatures of 15-28℃ on turnip, Raphanus sativus L., significantly differed. The longest duration was 10.8 days at 15℃ and the shortest was 5.1 days at 28℃. The longest adult longevity was 8.9 days at 25℃ and the shortest was 7.5 day at 28℃. The highest mean fecundity was 44.8 offspring/♀ at 28℃, and the lowest was 20.4 offspring/♀ at 15℃. Population parameters at different temperatures on turnip showed that both the intrinsic rate of increase (r) and the finite rate of increase (λ) were the highest at 28℃ (r = 0.4020/d, λ = 1.4947/d), and the lowest was at 15℃ (r = 0.1706/d, λ = 1.1860/d). The reproductive rate (R_0) was the largest at 28℃ (R_0 = 40.19 offspring/♀), and the smallest was at 20℃ (R_0 = 12.57 offspring/♀). The gross reproductive rate (GRR), was the longest at 25℃ (GRR = 83.96), and was the shortest at 15℃ (GRR = 60.98). The mean generation time (T), was the longest at 15℃ (T = 15.49), and the shortest at 28℃ (T = 9.19). The lower developmental threshold temperature for the nymphal stage was -1.2℃, and the thermal summation was 176.7 degree0-days. |
