In the matter of control of HLB, the subject of study by several research groups has been the use of biological agents: predators, parasitoids or pathogenic microorganisms that are capable of decreasing the population densities of Diaphorina citri not only in areas where HLB is already established, but also in undersized areas where the high psyllid populations have not yet been subjected to such intensive spraying of pesticides. This project has contributed to the prospecting and characterizati

This project aims at the development of phytotechnical processes and citrus varieties to contribute to the management of HLB based on experiments installed at the FCC in an area where HLB occurs. Several scion/rootstock combinations and five citrus seedling planting systems and intercropping with other species will be selected for production, in addition to the occurrence of Diaphorina citri and the incidence of HLB.

Psyllids are small sap sucking insects with generally very narrow host plant ranges. Some of them are pests that cause major economic losses in agriculture, on ornamental plants and in forestry. They damage the plants by directly removing large quantities of sap or by the transmitting diseases. The chemical control of red gum lerp psyllids in eucalypt plantations in Brazil, for instance, costs millions of reais per year due to intensive use of insecticides. Another example is the transmission of
