美洲斑潜蝇对不同番茄品种的选择性

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。

Selectivity of Liriomyz sativae to Different Varieties of Tomatoes

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 sativae's selectivity of 18 different varieties of tomatoes and materials was studied.The population 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,secondly 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 reduce the damage of Liriomyz sativae.
