Aulacorthum solani (Kaltenbach, 1843) - (foxglove aphid)

This aphid is widespread and polyphagous, attacking crops like potatoes, soybeans or vegetables. The feeding damage results in leaf chlorosis. In addition, it is also a vector of various plant viruses like the Potato leafroll virus (PLRV) or the Cucumber mosaic virus (CMV). Yield losses in soybean have been reported to reach 90% in Japan.

During its life cycle, A. solani does not change host plants and the cycle can be either holocyclic (with sexual reproduction) or anholocyclic (only parthenogenetic reproduction). In the holocyclic cycle, the overwintering stage are the eggs, and in the anholocyclic cycle the nymphs and adults.
