Chattanooga
Fluffy, white objects appearing in the air around Chattanooga have been identified as woolly aphids. These small creatures, covered in a waxy coating, can easily navigate through the air, raising both interest and concern among local residents.
Woolly aphids encompass several species, and their impact can vary significantly depending on which type is present. The woolly apple aphid is native to eastern North America, while the woolly hackberry aphid, which is introduced from Asia, has been noted for its rapid spread. First detected in Georgia in 1996, the woolly hackberry aphid has now made its way throughout the southeastern U.S., including states like Texas, Oklahoma, and California.
These aphids feed on plant or tree sap through their piercing, sucking mouthparts, producing a sticky byproduct known as honeydew. The accumulation of honeydew can lead to mold growth, particularly sooty mold, which can coat host trees and nearby surfaces, rendering them less visually appealing.
While the woolly hackberry aphids are predominantly nuisance pests, woolly apple aphids can have a more detrimental effect through the formation of galls on the roots of plants, which can impede growth. Gall-forming insects are typically specific to their host species.
In most cases, healthy trees do not require control measures for woolly aphids, although woolly apple aphids may necessitate interventions in certain situations. The presence of natural predator populations usually keeps woolly aphid numbers manageable, reducing the need for chemical insecticides.
However, in instances of severe infestations, options like plant removal or insecticide applications may be necessary. It is crucial to carefully read product labels before using any insecticides. Sprayed-on products might not effectively combat woolly aphids due to their protective waxy coverings; versus, systemic insecticides that are absorbed into plant tissues may offer better results.
Residents can manage the presence of woolly aphids by maintaining regular upkeep of their plants. This includes cleaning surfaces impacted by honeydew and using a strong stream of water to dislodge aphids from their host plants.
The populations of these aphids typically decline from late October to November, and they exhibit no visible activity during the winter months. As the presence of woolly aphids continues to garner attention in Chattanooga, there is a growing need for community education on their behaviors and control measures. Residents are encouraged to reach out to local extension offices for assistance and information.
