通过对7个茄科野生种在控制环境中的存活率、繁殖力和种群增长率的测定，评价了它们对桃蚜和大戟长管蚜的抗性水平。在茄上的存活率最低。capsicibaccatum、Solanum pinnatisectum和Solanum trifidum等3种材料对M. persicae和S.柑属capsicibaccatum、Solanum okadae和S. trifidum，M. Euphorphine。植物种类显著影响两种蚜虫的生殖力。蚜虫种群增长的整个植物的植物年龄的负面影响，但一般遵循的净繁殖率在不同的植物物种观察在套筒笼实验。M的人口。persicae在7份野生马铃薯材料中的生长速率存在差异，在S.柑属capsicibaccatum、Solanum polyadenium、Solanum tarijense和S.三裂体。M的数量。大戟属植物在不同的材料中也有差异，但最小的种群是从S.多聚腺苷酸这些结果可用于鉴定那些已知对科罗拉多马铃薯甲虫具有抗性的材料中对蚜虫的抗性来源。这项研究强调了在开发一个高通量筛选试验的蚜虫抗性兼容的马铃薯育种计划所涉及的困难。
Resistance level of seven accessions of wild Solanum species (Solanaceae) to Myzus persicae and Macrosiphum euphorbiae (Homoptera: Aphididae) was evaluated by measuring survival and fecundity during sleeve cage experiments and population growth on whole plants in a controlled environment. The survival was lowest on the Solanum circaeifolium spp. capsicibaccatum, Solanum pinnatisectum and Solanum trifidum accessions for M. persicae and on the S. circaeifolium spp. capsicibaccatum, Solanum okadae and S. trifidum, accessions with M. euphorbiae. Plant species significantly influenced the fecundity of both aphid species. Aphid population growth on whole plants was negatively affected by the age of the plant, but generally followed the levels of net reproductive rate on different plant species observed during the sleeve cage experiment. The population of M. persicae varied among the seven wild potato accessions with the lowest growth rates on S. circaeifolium spp. capsicibaccatum, Solanum polyadenium, Solanum tarijense and S. trifidum. The number of M. euphorbiae also varied among accessions but the smallest population was collected from S. polyadenium. The results can be used to identify sources of resistance to aphids within those accessions already known to be resistant to the Colorado potato beetle. This study highlights the difficulties involved in developing a high-throughput screening test for aphid resistance compatible with a potato breeding programme.
