Crape myrtles, Lagerstroemia spp., are popular landscape shrubs and small trees. Native to China, Japan, and Korea southward to Oceania, crape myrtles have been cultivated in the U.S. for more than 175 years. Cultivars range from 3-ft shrubs to 30-ft-tall trees, and they are graced with large panicles of white, pink, lavender, purple, red, and many colors in between. Among cultivars, crape myrtles have a wide range of tolerance to key pests and diseases, such as powdery mildew, flea beetles, crape myrtle aphids, and Japanese beetles. The plant’s flowers are widely admired by humans and can serve as nectar and pollen sources for pollinators. With the recent decline in pollinator health and diversity, pollinator visitation, pest susceptibility, and horticultural attributes should all be considered when choosing crape myrtle cultivars for home and commercial landscapes.

The silverleaf whitefly, also known as the sweet potato whitefly or Bemisia tabaci (Hemiptera: Aleyrodidae), attacks a wide range of plants, from ornamentals to warm-season vegetables. Whiteflies are active from mid-July to mid-October and are found gathered together on the underside of leaves during the daytime. Although 76 whitefly species are known to exist in the Southeastern U.S., only a few species cause serious problems in greenhouses and nurseries. These species include the greenhouse whitefly (Trialeurodes vaporariorum), banded wing whitefly (Trialeurodes abutiloneus), giant whitefly (Aleurodicus dugesii), citrus whitefly (Dialeurodes citri), cloudywinged whitefly (Dialeurodes citrifolii), and the silverleaf or sweet potato whitefly. Among several whitefly species, the silverleaf whitefly, particularly biotype B, is the most common and most destructive whitefly species in
nurseries in the Southeastern U.S.William G. Hudson, Shimat V. Joseph, and Rehan Arshad

The lantana lace bug, Teleonemia scrupulosa Stål (Tingidae: Hemiptera), is a serious pest of lantana (Lantana
camara L.). Although lantana is regarded as an invasive weed both in the United States and worldwide,
many popular cultivars continue to be planted in residential and public ornamental landscapes and gardens.
Previously, the lantana lace bug was deliberately introduced to several countries as a biological control agent for
lantana. Te lantana lace bug is also referred to as T. lantanae or T. vanduzeei in many publications. This publication covers the identification, biology, symptoms and management of lantana lace bugs.William G. Hudson and Shimat V. Joseph

Dahlias
Dahlias are among the most spectacular flowers you can grow in your garden. Hundreds of varieties are available, with flower sizes ranging from 1 to 14 inches in diameter. Almost any color except true blue can be produced in Georgia. In exchange for their beauty, dahlias require dedicated care. Most of them need special soil preparation, staking, watering during dry periods, disbudding and a strict insect control program. This publication contains information about successfully growing dahlias in Georgia.
