Abstract | ||||
Infestation of cowpea seeds with C. maculates resulted in 39.3 % to 58.5% damaged seeds according to seed variety. Kafr El-Sheikh-1 had 58.5% damaged seeds while this value lowered to 39.3% in seeds of Dokki 331. The percentages of damaged faba bean seeds ranged between 5.2 % and 17.4 % and the highest rate of damage seeds occurred in Giza 429. The highest weight of cowpea seed loss was shown with Kafr El-Sheikh-1 variety (61.6 %) while the least percent loss (42 %) was found with Dokki 331. Faba bean seeds attacked by C. maculates. Giza 843 suffered the least loss (8.3 %) while the maximum loss (28.3 %) occurred in the seeds of Giza 429. Seed viability of cowpea and faba bean decreased to 4.6% and 7.2%, respectively, when seeds were infested with C. maculates In case of cowpea, the highest reduction rate of seed germination (94.9 %) was found in Dokki 331 and these values reduced to 94,3 % in the case of faba bean Giza 429. | ||||
