| 摘 要： | 西花蓟马是一种世界性的入侵害虫,在不同地区呈暴发性危害。本文以莴苣、黄瓜和茄子3种蔬菜寄主为饲养材料,组建了西花蓟马的特定年龄生命表。结果表明,西花蓟马在3种寄主上具有不同的种群增长倍数,其在莴苣上最高,种群趋势指数(I)为30.09;在茄子上最低,种群趋势指数(I)为18.03。说明寄主是影响西花蓟马种群增长的因素之一,研究结果可为不同寄主上,西花蓟马的重点防治、作物布局调整等奠定基础。

| Abstract: | Frankliniella occidentalis is a worldwide invasive pest,caused explosive damage to lots of host plants in different region. The age specific life tables of F. occidentalis on three different vegetables（ lettuce,cucumber and eggplant）were established in this paper. The results showed that F. occidentalis had different population growth on the three vegetables,the highest index of population trend（ I） was on lettuce,with the value of 30. 09; the lowest was on eggplant,with the value of 18. 03. The results indicated that host was one of the reasons influencing the population development of F. occidentalis,and the data also could lay a foundation for the adjustment of crop distribution and the focal control of F. occidentalis on different hosts. |
