中文摘要 | 不同定溫下棉蚜 (Aphis gossypii Glover) 在番石榴 (Psidium guajava L.)、紫 花霍香薊 (Ageratum houstonianum Mill.) 及大花咸豐草 (Bidens pilosa L.) 三種 不同寄主植物上之族群介量,其內在增殖率 (rm) 及終極增殖率 (λ) 皆於 25℃ 時 達最大值 (番石榴上為 rm = 0.3924/日、λ = 1.4800/日,紫花霍香薊上為 rm = 0.5106/日、λ = 1.6653/日,大花咸豐草上為 rm = 0.3214/日、λ = 1.3766/日);淨 增殖率 (R0) 在番石榴與紫花香薊上,皆於 25℃ 時最高 (分別為 36.4、48.9 子代 /♀),在大花咸豐草上則於 20℃ 時最高 (35.1 子代/♀);在不同寄主植物上之平均 世代時間 (T) 皆隨著溫度的上升而逐漸縮短,至 30℃ 時最短 (分別為 8.8、7.0 及 9.7 日)。 |
英文摘要 | The population parameter of cotton aphid (Aphis gossypii Glover) on three host plants (Psidium guajava, Ageratum houstonianum, and Bidens pilosa) showed that the highest intrinsic rate of increase (rm) and the finite rate of increase (λ) were at 25 , of which ℃ r = 0.3924/day and λ = 1.4800/day on P. guajava, rm = 0.5106/day and λ = 1.6653/day on A. houstonianum, and rm = 0.3214/day andλ = 1.3766/day on B. pilosa. The highest net reproductive rates (R0) were 36.4 and 48.9 on P. guajava and A. houstonianum, respectively, at 25 , and 35.1 offspring/female on ℃ B. pilosa at 20 . The mean ℃ generation time (T) on the three host plants was reduced by an increase in temperature, the shortest was 8.8 days on P. guajava, 7.0 days on A. houstonianum, and 9.7 days on B. pilosa, respectively, all at 30℃. |
