This highly polyphagous species shows a prediliction for Cucurbitaceae and Malvaceae (cotton, mallow, hibiscus). It also attacks Citrus.
Among cultivated vegetables, damage is particularly marked in courgette, melon, cucumber, aubergine and strawberry.
In temperate countries such as Italy, this aphid always reproduces parthenogenetically.
In the United States, this species may be holocyclic, its primary host being Catalpa, Rhamnus or Hibiscus.
- With good resistance to summer heat, this aphid may produce nearly sixty generations a year.
- It has a mutually beneficial relationship with ants (ants making use of the honeydew from the aphids which, in return, are protected from their enemies).
Damage (*) is caused by the sucking of sap and the production of honeydew. The indirect attraction it exerts upon ants constitutes an additional problem.
This aphid is considered as a vector among others, of the Tristeza citrus fruit virus.
Found worldwide. In Africa, it is one of the major pests affecting the agricultural economy.
In northern Europe, it survives and increases only in glasshouses.
