Dietary range varies among Aphis craccivora populations associated with different host plants: Insights into the alfalfa–cowpea aphid system in Spain

We conducted host specialization trials with three different Aphis craccivora populations. They revealed the generalist nature of the alfalfa‐origin population, which thrived when shifted to both black locust and vetch. Conversely, populations originating from black locust and vetch showed high host specialization, performing poorly when shifted to ...
