摘　　要： 1993 年～1996 年,在陕西耀县、乾县对101 种植物的24 次调查结果表明,当地桃蚜的寄主植物有43 种,其中主要危害寄主36 种,偶发寄主7 种,越冬寄主3 种。通过系统调查,查明了桃蚜在不同寄主植物上的数量变化规律和在不同寄主植物上的迁移规律,为桃蚜种群数量测报和防治提供了可靠的依据。 species of plants were systematically investigated 24 times in order to make clear of host plant ranges of the green peach aphid, Myzus persicae (Sulzer) in both Yaoxian and Qianxian, Shaanxi during 1993～1995.Results showed that of 43 species of plants, which were proved to belong to host plants of the aphid and were recorded in above noted areas, 36 species were seriously damaged by the aphid;7 species were occasionally damaged and 3 species were regarded as over wintering hosts. The population laws of number fluctuations and migration on 11 species of main host plants were found, which laid a solid basis for forecast and control of green peach aphid.
