Lace bug Phatnoma annulipes

Systematic position. This species belongs to the family Tingidae, commonly known as lace bugs, within the order Hemiptera. These insects are easily recognized by their delicate, net-like wing patterns, which are characteristic of this taxonomic group. They are well-adapted to life on the abaxial surface of host leaves.

Host plants and economic significance. Phatnoma annulipes is a specialized feeder that targets various plants, primarily focusing on solanaceous species and other susceptible ornamental plants. While their impact is often localized, heavy infestations can cause significant economic losses in greenhouses and specific geographic regions where climate conditions favor their rapid reproduction.

Biology and lifecycle. The lifecycle of this lace bug includes egg, nymphal stages, and adult phases. The eggs are typically inserted into the leaf tissue or laid along the leaf veins. Nymphs pass through several instars, feeding throughout their development. Their ability to reproduce multiple generations per season makes them a persistent threat to host plant health.

Nature of damage. Damage is caused by both nymphs and adults feeding on the sap of the plant. As they pierce the epidermal cells, they create characteristic chlorotic stippling on the leaves. Severe damage leads to foliage yellowing, necrosis, and premature abscission, which effectively limits the photosynthetic capacity and vitality of the affected crop.

• Regular field monitoring for stippling signs on foliage.
• Targeted application of systemic insecticides during early nymphal stages.
• Maintaining field sanitation by removing crop residues and weeds.
• Encouraging natural predators such as lacewings and spiders.
• Implementing cultural practices to ensure plant vigor and resilience.
