摘    要:本试验研究并比较了外来入侵物种西花蓟马Frankliniella occidentalis(Pergande)与本地物种烟蓟马Thrips tabaci Lindeman的生物学特性,包括种群增长速度、发育历期、成虫寿命、孤雌生殖方式下的产卵量以及产卵规律等几个方面。结果显示,当以相同的数量在紫甘蓝上饲养时,只经过3代,烟蓟马的种群数量就可以达到西花蓟马的3倍,随后对2种蓟马种群的性别比进行了鉴定后发现,西花蓟马种群的雌雄比为2.8∶1,而烟蓟马种群中的所有个体均为雌性。除了2龄若虫期和预蛹期之外,烟蓟马在紫甘蓝上的发育历期明显长于西花蓟马,而其雌虫的平均寿命显著短于西花蓟马雌虫,分别是24.94d和43.35d。进行孤雌生殖时,西花蓟马的终生产卵量明显多于烟蓟马,但是在日均产卵量方面,这一情况却相反。

关 键 词:西花蓟马  烟蓟马  生物学特性

Abstract:Experiments were carried out to compare some biological characteristics of invasive Frankliniella occidentalis (Pergande) and native Thrips tabaci Lindeman,including population growth rate,sex ratios,developmental duration,longevity and parthenogenesis.The results show that numbers of T.tabaci were almost three times that of F.occidentalis after three generations.The sex ratio(female/male)of F.occidentalis was 2.8:1 but all T.tabaci were female.The developmental duration of T.tabaci was significant longer t...
Keywords:Frankliniella occidentalis  Thrips tabaci  biological characteristics
