中文摘要 | 銀葉粉蝨為設施栽培洋香瓜之關鍵害蟲,本研究以洋香瓜 (秋華二號 ) 葉片飼育銀葉粉蝨,在不同溫度下觀察其生活史,分析溫度與其發育臨界等生活參數之關係,作為開發其綜合管理技術之參考依據。在 16~34℃之 10個定溫下,銀葉粉蝨未成熟蟲期的累積死亡率以 26及 28℃時最低,約為 6%。在 16~28℃等定溫時,銀葉粉蝨由卵至成蟲的平均發育時間,依溫度升高而縮短,約 15.4~55.3日。在 30~34℃時,發育時間依溫度升高而增長,約 15.8~21.1日。在 16~28℃時估算卵發育至成蟲的發育速率 (D)與溫度 (T) 之直線廻歸模式為 D (T) = -0.044321 + 0.003849 T,由此推算卵至成蟲的發育臨界低溫為 11.5 ℃,而其發育總積溫 259.807日度 (degree-days)。以 16~34℃觀察結果估算 Lactin-2非線性廻歸模式中各參數之數値,其中致死溫度為 37.6℃,由卵發育為成蟲的發育最適溫度 (optimal temperature) 為 29.9℃,發育臨界低溫 (low temperature threshold) 為 9.1℃。 |
英文摘要 | Bemisia argentifolii (Bellows & Perring) is a major pests of cantaloupe when cultivated in a net house. We measured its life history at the constant temperatures of 16,18,20,22,24,26,28,30,32 and 34℃ on cantaloupe, in order to evaluate the effect of temperature on development of B. argentifolii. The results showed that the lowest mortality of B. argentifolii from egg to adult was 6% at 26℃ and 28℃. The whole life cycle lasted from 15.4 to 55.3 days at 16-28 ℃ on cantaloupe. The developmental rate (D) was increased with the increase in temperature (T), as shown in the linear regression equation: D = -0.044321 + 0.003849 T. However, when the temperature reached approximately 30 to 34℃ the developmental rate was slowed down and the life cycle lasted 15.8 to 21.1 days. The lowest developmental threshold temperature and degree-day (DD) requirements from egg to adult were 11.5℃ and 259.807 DD, respectively. A nonlinear temperature-dependent model (Lactin-2) fitted well to the data for 16 to 34℃. Accordingly, the lethal upper temperature was estimated to be 37.6℃, and the optimal temperature and developmental temperature threshold of B. argentifolii from egg to adult was estimated to be 29.9 ℃ and 9.1 ℃, respectively. |
