Eggplant lace bug (Urentius hystricellus)
It is a small bug (about 3 mm in length), brownish in colour. Its body is covered with spines and the wings show a distinct lace-like appearance. Nymphs resemble adults, but are initially wingless, developing wings as they grow. Both adults and nymphs are usually found in groups on the underside of leaves. They suck sap from the leaves causing whitish to yellowish mottled patches on the leaves. In case of serious infestations the leaves turn entirely yellow and drop off. Attacked leaves are speckled with small black shiny spots, which are the faeces of the bugs.
Spray neem products. They have given effective control of lace bugs on eggplants. The lace bug (Urenthius sp.) was repelled from eggplant plots treated with neem oil (5, 10 and 20%). However, concentrations of 10 and 20% showed phytotoxic effects.
Weekly sprays of an aqueous neem seed extract (50 g/l) and 2% neem oil gave good results against another species of lace bug (Corythaica cyathicollis) attacking eggplant in the Caribbean (Ostermann and Dreyer, 1995).
