Seeds susceptibility of eight broad bean varieties to (F.) and (L.) infestation were studied for the first time in free- and no-choice methods in the laboratory of Plant Protection Department, Faculty of Agriculture, Zagazig University. The relation between certain seed physical characteristics and some biological and and infestation parameters of both insects in the two studied methods were evaluated. None of these varieties were resistant to both insects, showing various levels of susceptibility. Biological and infestation parameters were significantly different among varieties except the developmental period. In free- choice method, Giza 3 was the most susceptible variety to both insects, since produced the highest progeny of 246.67 and 75.67 adults and susceptibility index (SI) of 10.25 and 7.42, respectively, while the least susceptible variety was Giza 716. In no- choice method, Nubaria 5 and Sakha 1 were the most susceptible varieties to . , while Nubaria 3 and Giza 3 to . . Differences between physical characters of varieties were significant. Seed hardness were correlated negatively and seed coat thickness positively with laid eggs, progeny and (SI) of both insects in free-choice method. Also seed coat thickness correlated positively with weight loss and seed damage (%) of . and negatively of . To reduce seed losses the cultivation of the least susceptible variety (Giza 716) is encouraged and considered for breeding purposes to avoid insecticide usage.
在扎加齐格大学农学院植物保护系实验室，首次采用自由选择法和无选择法研究了8个蚕豆品种对（某种真菌）和（某种昆虫）侵害的种子敏感性。评估了两种研究方法中某些种子物理特性与两种昆虫的一些生物学及侵害参数之间的关系。这些品种对两种昆虫均无抗性，表现出不同程度的敏感性。除发育时期外，各品种间的生物学和侵害参数存在显著差异。在自由选择法中，吉萨3号是对两种昆虫最敏感的品种，分别产生了246.67头和75.67头成虫的最高后代数量，敏感性指数（SI）分别为10.25和7.42，而最不敏感的品种是吉萨716。在无选择法中，努巴里亚5号和萨哈1号是对（某种昆虫）最敏感的品种，而努巴里亚3号和吉萨3号是对（另一种昆虫）最敏感的品种。品种间的物理特性差异显著。在自由选择法中，种子硬度与两种昆虫的产卵量、后代数量和（SI）呈负相关，种皮厚度与它们呈正相关。种皮厚度与（某种昆虫）的重量损失和种子损伤率（%）也呈正相关，与（另一种昆虫）呈负相关。为减少种子损失，鼓励种植最不敏感的品种（吉萨716），并考虑将其用于育种目的，以避免使用杀虫剂。
