Is this a Minor Pest?
Yes
Minor Pest Title
Legume aphid (Aphis craccivora)
Minor Pest Description
It is a widespread pest of cowpeas. Aphids suck sap on stems, terminal shoots and petioles of seedlings, and on pods and flowers of mature plants.
A heavy attack can cause death of young seedlings, stunting and delay in flowering on older plants. However, it is more important as vector of virus diseases (e.g. the cowpea mosaic virus).
Minor Pest What to do.
- Use resistant varieties where available.
- Monitor build-up of aphids and natural enemies.
- Use neem seed or leaf extracts if necessary.
