Orthosiphon stamineus Bentham, a medicinal plant in the family Lamiaceae, is used to make a wellknown herbal tea in many countries including Malaysia. Since its establishment as an important cash crop, theherb has been relatively free from any serious insect problems until recently. In Selangor, Malaysia we observed theherb heavily infested by the lace bug Cochlochila bullita Stål (Heteroptera: Tingidae). This is the first record of itsoccurrence in Malaysia and also the first record on the host plant, O. stamineus. The lace bug damages the host plantby piercing and sucking young leaves and shoots, resulting in the curling and drying of the leaves and shoots. Theinfestation pattern and survival of C. bullita on O. stamineus indicates this lace bug has the potential to be a seriouspest of this medicinal plant.
