out to study of the number of bean aphid (aphis craccivora) and visual damage scores in yardlong bean and
cowpea. The experimental design was a Randomized Complete Block Design (RCBD). The results showed that
the highest number of bean aphid having severely on visual damage levels was scored to be found on maternal line
(Selected – PSU) about 7,832.3 aphids/plant to be equal to 3.80 points, as for the lowest number of bean aphid and
visual damage scores were obtained from parental line (IT82E – 16) about 1,506.80 aphids/plant to be equal to
2.48 points. While other generations were found and an average number of bean aphid and visual damage scored
between paternal and maternal line.
