Citrus leafminer (Phyllocnistis citrella) is found in Georgia and states along the Gulf of Mexico. Leafminer damage to foliage can stunt the growth of young trees and make trees more susceptible to citrus canker where the pathogen is present. Mature trees can better tolerate the damage although heavy infestations may reduce production. This publication discusses the identification, chemical control, noninsecticidal control, and homeowner control options for citrus leafminers.

Azalea Bark Scale
Azalea bark scale (ABS) poses a serious threat to azaleas, rhododendron, and Pieris (Andromedas) in Georgia. ABS is a soft scale insect; the nymph and female soft scales secrete a protective coating of waxy crust on their body that cannot be separated from the scale insect. ABS also is found on blueberry, hawthorn, huckleberry, poplar, and
willow. ABS is found in cracks or crevices in the surface of the bark, and also in areas where azalea branches fork. ABS can undergo two generations per year in Georgia.
Symptoms of ABS infestation include dropping yellow leaves and dying branches. Developing nymphs and females excrete a sugary syruplike liquid called honeydew on to the bark and leaves. As time passes, the surface of the bark, and sometimes the leaves, turns black because it gets infested with a sooty mold fungus that
feeds on the sugary secretions. The white crusts of scale insects are easily visible when the azalea bark turns completely black. An ABS infestation rarely kills the plant unless it is extremely severe and uncontrolled.|

The sugarcane beetle has been a significant pest of many crops, including sugarcane, corn, sweet potato, and rice, for more than 100 years. It is a native species commonly found in turfgrass. While low numbers of beetles in an area generally are not regarded as pests, increasing numbers of adult beetles have been causing damage to turfgrass stands throughout the Southeastern U.S.

The brown marmorated stink bug is a landscape and agricultural pest in the United States. They seek dark and dry sites—such as a vehicle parked near trees—in the fall in which to overwinter. This pest is reported to feed on more than 170 plant species, including fruits, vegetables, and ornamental plants. This stink bug also is a nuisance pest as they aggregate and overwinter in man-made structures beginning in late fall.
