中文摘要 | 卵形捕植蟎活動期(幼、若蟎及成蟎)在胡瓜植株上之密度顯著以中位葉為最高(1.38 ± 0.50 隻/葉),依Taylor及Iwao的方法,屬於低程度之聚集分布型(a=0.311,b=1.074;α=1.477, β=1.014)。卵形捕植蟎族群密度於秋季至翌年春季(10月~5月)受溫度影響呈正相關關係,但夏季族群則未顯示受溫度影響;此外,週降雨量對捕植蟎族群密度則無影響。 |
英文摘要 | A higher density (1.38 ± 0.50 individuals/leaf) of active stages (larvae, protonymph, deutonymphs and adults) of Amblyseius ovalis was found on the middle leaves of cucumber. The spatial distribution patterns of A. ovalis was aggregated and was determined by Taylor’s Power Law (a: 0.311, b: 1.074) and Iwao’s Mean Crowding Regression (α: 1.477, β: 1.014). Population density of predacious mite was significantly depended on temperature during the period of October ~ May, but not in summer season (June ~ September). Weekly precipitation did not positively influenced the densities of A. ovalis. |
