中文摘要 | 雅板背薊馬 (Neohydatothrips gracilipes) (纓翅目:薊馬科) 是台灣新紀錄的害蟲之一。本研 究於 20、25、30℃三種定溫,相對濕度為 70 ± 5%及光週期 12D:12L 下,以蜀葵葉片飼養觀察 其生活史,三種定溫下其卵孵化率均達 90%以上;在 20℃未成熟期發育所需時間為 27.7 天,30 ℃下僅需 11.0 天,平均總發育日數隨溫度升高而縮短。成蟲壽命隨著溫度的增加而縮短,但產卵 量不受影響。每雌每日平均產卵以 30℃之 5.3 粒為最高,一生總產卵量達 89.6 粒。30℃定溫下其 族群介量內在增殖率 (r) 為 0.1900,淨生殖率 (Ro) 為 46.79,終極增殖率 (λ) 為 1.2092,均是 最高值,而平均世代時間 (T) 20.24 天為最短。此研究的結果可提供物候學模式有用的參考資料, 也有助於台灣建立雅板背薊馬的有害生物監測計畫。 |
英文摘要 | The Neohydatothrips gracilipes (Hood) (Thysonoptera: Thripidae) are one of the newly recorded pests in Taiwan. This study investigated the life history of N. gracilipes on Althaea rosea Cav. at three constant temperatures (20, 25, and 30o C) under 70% ± 5% RH and a 12L : 12D photoperiod. Ninety percent of the eggs hatched at each of these temperatures. The duration of the entire developmental period was 27.7 days at 20°C, but was only 11.0 days at 30°C. The developmental period decreased with the increase in temperature. At 30°C, a female could at most produce an average of 5.3 eggs per day and a maximum of 89.6 eggs over the entire oviposition period. At 30°C, the intrinsic rate of increase (r) was 0.1900 day-1, the net reproductive rate (R0) was 46.79 offspring, the finite rate of increase (λ) was 1.2092 day-1, and the mean generation time (T) was 20.24 days. The results obtained in this study provide useful information to aid in the development of a phenology model for pest monitoring programs of N. gracilipes in Taiwan. |
