| Abstract | ||||
| The field experiment was conducted during summer and winter seasons to evaluate seven varieties of beans (Phaseolus vulgaris L.) for their relative susceptibility against some sap sucking pests Tetranychus urticae Koch, Bemisia tabaci (Gennadieu), Aphis craccivora Koch, Thrips tabaci Lindquist and leaf miner, Liriomyza trifolii (Burgess). The tested bean varieties were: Medina (V1), R9251 (V2), Teresa (V3), Luvalde (V4), Al-Hanna (V5), Alexandria (V6) and Excalibur (V7). None of the varieties escaped the infestation of all these pests. Generally the population of T. urticae and T. tabaci were higher in summer than in winter, while population of B. tabaci and L. trifolii were higher in winter. Relative susceptibility of bean plants changed according to plantation season as, V6, V6, V5, V6 and V3 hosted the less number of T. urticae, B. tabaci, A. craccivora, T. tabaci and L. trifolii in winter season, respectively. While in summer plantation, V5, V1, V4, V1 and V7 hosted the less number of the same pests, respectively. | ||||
