摘    要:西花蓟马Frankliniella occidentalis(Pergande)是传入我国的重要入侵害虫,在贵阳地区对豆科蔬菜为害十分严重。在25℃条件下,组建了西花蓟马取食大豆叶片、豇豆叶片、四季豆叶片和四季豆豆荚时的实验种群生命表。结果表明:西花蓟马未成熟期取食四季豆豆荚时存活率最高,取食其它3种豆科蔬菜时存活率相差不大。西花蓟马取食四季豆豆荚时内禀增长力最高为0.1626,取食豇豆叶片时最低为0.0834,净增值率也是取食四季豆豆荚时最高,取食大豆叶片时最低,表明四季豆豆荚最有利于西花蓟马的生长发育和繁殖。在不同豆科蔬菜上的稳定年龄组配中未成熟期所占的比例很大,而成虫期所占的比例相对较小。

关 键 词:西花蓟马  豆科蔬菜  实验种群  生命表

Abstract:Frankliniella occidentalis(Pergande) is one of the most important invasive pests,which has caused serious damage on leguminous vegetables in Guiyang,Guizhou.The life tables of experimental populations of F.occidentalis feeding on leaves of Glycine max,Vigna sinensis,Phaseolus vulgaris and pod of P.vulgaris were constructed at 25℃.The results showed that the survival rate of immatures of F.occidentalis was highest on pod of P.vulgaris,and it was similar on other three leguminous vegetables.The intrinsic rate of natural increase(rm) was highest on pod of P.vulgaris(0.1626) and lowest on leaf of V.sinensis(0.0834).The net reproductive rate(R0) was highest on pod of P.vulgaris,and lowest on leaf of G.max.The results indicated that pod of P.vulgaris was the most suitable food to F.occidentalis.In stable age composition,the percentage of immature period was higher and that of adulthood was lower.
Keywords:Frankliniella occidentalis  leguminous vegetables  experimental population  life table
