Eggplant lace bug

Taxonomic position. The eggplant lace bug (Corythaica carinata) belongs to the order Hemiptera and the family Tingidae. It is a specialized pest known for the intricate, lace-like venation on its wings and pronotum, which serves as both structural support and camouflage.

Host plants. This pest primarily targets plants within the Solanaceae family. Eggplants are its preferred host, but it also causes significant damage to tomatoes, potatoes, and various wild species within the nightshade family, which act as reservoirs for the pest population.

Biology and life cycle. Corythaica carinata overwinters as adults in soil debris or protected areas under foliage. In the spring, females lay their eggs on the undersides of leaves. The life cycle involves several nymphal stages that are wingless and similar in appearance to the adults, gradually maturing into reproductive adults over the growing season.

Damage and economic impact. Both nymphs and adults feed by piercing leaf tissues and extracting cell sap. This feeding behavior results in characteristic stippling, chlorosis, and sometimes necrosis of the leaf blade. Severe infestations can lead to premature leaf drop, reduced plant vigor, and a substantial decrease in fruit quality and quantity.

Control measures. Integrated pest management (IPM) is essential for controlling lace bug populations. Effective strategies include:

• Removing and destroying infested plant residues after harvest.
• Managing weed populations to eliminate alternative hosts.
• Applying systemic or contact insecticides when population densities reach threshold levels.
• Promoting biological control through the preservation of natural predators in the field.
