Brazil, the world's largest citrus fruit producer, is combating the psyllid, Diaphorina citri, and the disease it transmits, greening. This pest, which resides in tropical climates, causes significant damage to citrus trees by sucking sap and spreading the disease through its eggs. Greening, an incurable disease, is symptomized by yellow or irregularly spotted leaves and necessitates the removal of infected trees. The absence of a cure necessitates the use of insecticides for prevention and poses threats to citrus production and global market income.
