The black bean aphid, Aphis fabae Scopoli (Hemiptera: Aphididae), is one of the important pests of sugar beet. The relative impact of resistance, including antibiosis and antixenosis of five sugar beet cultivars (Doroti, Perimer, Pershia, Rozier and 006) on A. fabae was studied under laboratory conditions using clip cages. The antibiosis test was based on life table parameters. Significant differences on developmental time, mean number of nymphs/aphid/day, fecundity, and adult longevity of A. fabae were found across tested sugar beet cultivars. In addition, there were significant differences among the sugar beet cultivars for population growth parameters such as the intrinsic rate of natural increase (r m ), net reproductive rate (R 0), finite rate of increase (λ), doubling time (DT), and mean generation time (T) of A. fabae. The highest and lowest (r m ) values were observed on Pershia (0.449 nymphs/female/day) and Perimer (0.358 nymphs/female/day), respectively. No significant differences were found for the preference of the black bean aphid, and antixenosis had no effect on resistance against this aphid. As a result, our findings showed that the Pershia cultivar was a relatively susceptible host plant. Two cultivars (Perimer and Rozier) were relatively resistant to A. fabae, which could prove useful in the development of IPM programs for this aphid in sugar beet fields.
黑豆蚜，豆蚜（半翅目：蚜科），是甜菜的重要害虫之一。在实验室条件下，使用夹笼研究了五个甜菜品种（多罗蒂、佩里默、佩尔西亚、罗齐尔和006）的抗性（包括抗生性和抗选择性）对豆蚜的相对影响。抗生性试验基于生命表参数。在测试的甜菜品种中，发现豆蚜的发育时间、若虫/蚜虫/天的平均数量、繁殖力和成虫寿命存在显著差异。此外，甜菜品种之间在豆蚜的种群增长参数上也存在显著差异，如自然增长率（rm）、净繁殖率（R0）、有限增长率（λ）、加倍时间（DT）和平均世代时间（T）。在佩尔西亚（0.449若虫/雌虫/天）和佩里默（0.358若虫/雌虫/天）上分别观察到最高和最低的（rm）值。黑豆蚜的偏好没有显著差异，抗选择性对这种蚜虫的抗性没有影响。因此，我们的研究结果表明，佩尔西亚品种是相对易感的寄主植物。两个品种（佩里默和罗齐尔）对豆蚜相对抗性较强，这在甜菜田针对这种蚜虫的综合虫害管理计划的制定中可能会很有用。
