Abstract

Tuta absoluta (Meyrick) is a serious pest of tomato throughout the world. The life history and the life table parameters of T. absoluta were studied on 12 different commercial tomato cultivars. The longest larval developmental period (12.92 ± 0.11 days), the longest total developmental time (26.20 ± 0.22 days), the longest total pre-oviposition period (29.31 ± 0.63 days) and the shortest oviposition period (5.08 ± 0.43 days) were recorded on Korral cultivar. The highest pupal mortality was found on Korral (23.53%) and the lowest larval and pupal growth indices were observed on Korral (6.57and 8.87, respectively). The highest and the lowest overall mortalities were observed on Korral (35.00%) and on Valouro (21.67%), respectively. The lowest and the highest intrinsic rate of increase (rm) were found on Korral (0.1046 ± 0.0005 day) and on Valouro (0.1584 ± 0.0002 day) cultivars. Also the lowest finite rate of increase (λ) (1.1102 day) and the highest doubling time (6.63 days) of the tomato leafminer were observed on Korral cultivar. Therefore, it was concluded that among the 12 tomato cultivars that were studied in this research, Korral was relatively unsuitable to T. absoluta and can be used in the integrated control programs (IPM) of this pest.

实验室条件下12个商品番茄栽培品种上绝对灰蛾的生活史和生命表参数

番茄枯病(Tuta absoluta, Meyrick)是一种世界性的严重番茄害虫。研究了12个不同商品番茄品种的赤霉病生活史和生命表参数。Korral品种幼虫发育时间最长(12.92±0.11 d)，总发育时间最长(26.20±0.22 d)，总预产卵期最长(29.31±0.63 d)，产卵期最短(5.08±0.43 d)。蚕蛹死亡率最高(23.53%)，幼虫和蛹生长指数最低(分别为6.57和8.87)。总死亡率最高的是科拉尔(35.00%)，最低的是瓦卢洛(21.67%)。内在增长率最高的品种是科拉尔品种(0.1046±0.0005 d)和瓦鲁洛品种(0.1584±0.0002 d)。Korral品种番茄叶螨的有限增殖率λ最低(1.1102 d)，倍增时间最高(6.63 d)。综上所述，在本研究的12个番茄品种中，Korral番茄品种对绝对白僵虫相对不适宜，可用于该害虫的综合防治。
