Lantana lace bug

The Lantana lace bug (Teleonemia australis) is a member of the insect order Hemiptera and the family Tingidae. These insects are specialized herbivores, well-known for their lace-like wing structure and their host-specific association with plants from the genus Lantana.

The primary host plant for this pest is Lantana camara. While in some regions it is used for biological control of invasive lantana, in ornamental horticulture, it is considered a significant pest that damages the aesthetic and physiological state of the plants.

The life cycle of the lace bug includes egg, nymph, and adult stages. Females typically insert eggs into the leaf tissue or leaf veins. The development process is highly dependent on environmental factors, particularly ambient temperature, which dictates the duration of the life cycle and the number of generations per year.

The feeding habit involves piercing leaf tissue to suck out cell contents. This results in distinct symptoms, including stippling, chlorosis, and the formation of necrotic spots. As damage progresses, the leaves become discolored, wither prematurely, and eventually drop, causing severe stress to the entire plant.

Management strategies for Teleonemia australis focus on reducing population numbers to maintain plant health. Growers should rely on a combination of cultural practices, such as removing infested plant debris, and the targeted application of insecticides. Systemic products are often the most effective, as they reach the insects residing on the underside of the leaves.
