Citrus Greening Disease

Citrus Greening Disease

A bacterial disease that has affected all varieties of citrus in Florida is something called citrus greening. This pathogen blocks the nutrient carrying

tissue in the tree and results in poor tasting, misshapen fruit and eventually causes the death of the tree. Many home owners have lost their prized citrus in recent years to this problem because there is currently no treatment or cure for the disease. The bacteria is spread by a tiny insect

named the Asian citrus psyllid (Diaphorina citri). For more information: http://entnemdept.ufl.edu/creatures/citrus/acpsyllid.htm.

Parasitic Wasps

But there are other insects that prey on the psyllids. One is the parasitoid wasp Tamarixia radiata. This tiny wasp lays its eggs on the pest psyllids and the maturing wasp larvae consume them from the inside. They won’t kill all of the psyllids, but they may help reduce their numbers and slow the spread of citrus greening among home owner citrus. The Florida Department of Agriculture is raising these wasps and making them available to home owners free of charge to release on their citrus trees.
