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 ,蛹重最重。

Abstract: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...
