摘　　要：为了弄清楚不同番茄品种对番茄刺皮瘿螨Aculops lycopersici(Massee)的抗感性程度,通过田间调查、室内盆栽接螨和离体培养等方法,考察了12个番茄品种(系)(多茸毛类YZ618和YZ619;少茸毛类YZ419,YZ507和YZ504;野生品系YZ7和YZ5;叶黄类YZ401;常规品系YZ406,YZ412,YZ413和YZ515)上番茄刺皮瘿螨的种群发育情况。结果表明:番茄刺皮瘿螨在不同番茄品种(系)上的种群密度有明显差异,野生品系YZ7及多茸毛品系YZ618和YZ619上较低,少茸毛品系YZ504,YZ507和YZ419较高。不同番茄品种(系)可能是通过影响螨的存活率和产卵能力来影响在品种(系)上的种群发展。离体培养观察发现,番茄刺皮瘿螨的存活率在少茸毛品系YZ504和YZ507上最高,其次是品系YZ419,野生品系YZ7上最低。在YZ504上的产卵量最大,YZ419和YZ507次之,YZ7最小。根据实验种群参数判断,野生品系YZ7及多茸毛品系YZ618和YZ619感螨程度低,为抗性品系;少茸毛品系YZ504,YZ419和YZ507感螨程度高,为感螨品系。In order to understand the resistance level of different tomato lines to the tomato russet mite,Aculops lycopersici（Massee）,the development of the mite was studied in the field and laboratory on 12 tomato lines（the more hair lines,YZ618 and YZ619;the less hair lines,YZ419,YZ507 and YZ504;the wild lines,YZ7 and YZ5;the yellow-leaf line YZ401;the conventional lines,YZ406,YZ412,YZ413 and YZ515）.The results indicated that there were significant differences in population density of the mite on different tomato lines,which was high on YZ504,YZ507 and YZ419 and low on YZ7,YZ618 and YZ619.There were also notable discrepancies in the survival rate,developmental duration,egg production and other examined parameters of the experimental populations of the mite on different lines.The highest survival rate was found on the less hair lines YZ504 and YZ507,the second on YZ419,and the lowest on YZ27.Meanwhile,the highest egg production was found on YZ504,the second on YZ507 and YZ419,and the lowest on YZ7.Judging from the life parameters of the experimental populations of the mite,we concluded that YZ7 and YZ618 lines were resistant to the mite,while YZ504,YZ419 and YZ507 lines were susceptible to the mite.
