摘　　要：在温度 (2 7± 1 )℃、湿度为 70 %± 5 %的实验室条件下 ,测定了菜豆属矮生菜豆 (无架 )、西宁豆、83 -B架豆、白花架豆、新春架豆等 5个菜豆品种 (系 )对美洲斑潜蝇种群参数的影响。结果表明 ,美洲斑潜蝇的各虫态发育历期 ,成虫寿命 ,卵、幼虫和蛹的存活率 ,蛹重 ,成虫产卵量和持续产卵期在 5个品种 (系 )间均存在显著性差异 (α=0 .0 5 )。其中美洲斑潜蝇在选择性弱的品种 83 -B架豆上表现为幼虫、蛹的历期最长 ,蛹的存活率最低 ;在选择性强的白花架豆上则表现为卵 -蛹的历期最短 ,幼虫存活率最高 。The populations parameters of the leafminer Liriomyza sativae in five Phaseolus vulgars varieties were tested at T =27±1℃ and with RH =70%±5% in the laboratory. The result showed that the developmental duration, survival rate, pupa weight, oviposit duration, fecundity and longevity of L. sativae were significantly different in 5 varieties of Phaseolus vulgars ( α =0 05). L. sativae exhibit nonpreference for 83 B, The developmental duration of larvae and pupa was the longest, the survival rate of pupa was the lowest. In preference varieties Baihua, the developmental duration from egg to pupa was the shortest, the survival rate of larvae was the highest, the pupa was the weightest.
