The Impact of Bean Varieties on the Life table and Population Dynamics of the Black Bean Aphid, Aphis fabae Scopoli (Hemiptera: Aphididae)

The black bean aphid, Black Bean Aphid, Aphis fabae Scopoli (Hemiptera: Aphididae) is a significant pest of common beans worldwide, causing damage both through direct feeding and by transmitting viruses. The selection of resistant varieties is the primary strategy in integrated pest management for controlling Aphis fabae Scopoli. The study of the development, reproduction, and population parameters of the black bean aphid was conducted on two different bean cultivars, Gina and Romano, under controlled conditions. Life table parameters were estimated using the age-stage, two-sex life table method. Population parameters were lower in the Romano variety. The results indicated that bean cultivars significantly impacted the biology of A. fabae, with Gina being the most favorable cultivar for its life cycle. These findings could be applied to the development of a pest management program targeting this aphid.
