美洲斑潜蝇对不同番茄品种的选择性

Selectivity of Liriomyz sativae to Different Varieties of Tomatoes

[目的]明确不同番茄品种对美洲斑潜蝇的选择性差异。[方法]在温湿度恒定的小气候环境中,研究了美洲斑潜蝇对18个不同番茄品种及材料的选择性。通过零频率估计法测定了美洲斑潜蝇幼虫的种群密度,同时调查虫情指数。[结果]美洲斑潜蝇对不同番茄品种的选择性存在差异。野生番茄品种ZBNH11的虫情指数最低,其次是包头市农业科学研究所选育出的15个番茄品种及材料,而引进的钻红八号和普罗旺斯的虫情指数最高。[结论]研究结果为合理利用抗性品种减轻美洲斑潜蝇危害提供了理论依据。

[ Objective] The aim was to clear selectivity difference of Liriomyz sativae to different varieties of tomatoes. [ Method] In a constant temperature and humidity environment, Liriomyz sativae9 s selectivity of 18 different varieties of tomatoes and materials was studied. The popula-tion density of the larvae of the species was determined by the zero frequency estimation method,and the index of the index was also investigated.[Result] The species were different in different varieties of tomato varieties. The wild tomato varieties ZBNH11 had the minimum pest index,sec-ondly was the 15 tomato varieties and materials which was selected by Baotou City Research Institute of Agricultural Sciences,and the introduction of varieties like Zuanhong 8 and provence had the highest pest index. [ Conclusion] The results provide reference for using resistant varieties to re-duce the damage of Liriomyz sativae.
