Ants associated with Diaphorina citri and their role in its biological control in South Florida

As a vector of citrus greening, Diaphorina citn is considered the major insect problem for the citrus industry in Florida. Two specific parasitoids of this pest has been introduced, but the parasitism rates are beyond satisfactory. One of the reasons of this lack of control could be the interaction...
