Abstract

Plant associations for Teleonemia nigrina Champion, a widely distributed Nearctic lace bug, are reviewed, and records that might not represent true host relationships are questioned. To gain a better understanding of the host-plant range of T. nigrina, its hosts were recorded during fieldwork, mainly in the southern United States (62 sites, 12 states), from 1995 to 2009. Plants on which nymphs were observed belonged to the asterid families Plantaginaceae (2 spp.), Scrophulariaceae (5 spp.), and Verbenaceae (7 spp.). Twelve of the 14 plant species represent new host records. The tingid was found most often on Aureolaria pectinata (Scrophulariaceae), Plantago aristata (Plantaginaceae), and Glandularia and Verbena spp. (Verbenaceae). Nymphs were observed on upper and lower leaf surfaces and reproductive structures, with foliar chlorosis evident on the upper surfaces and dark excrement on lower surfaces; severe feeding resulted in the death of Mimulus × hybridus (Scrophulariaceae) in a landscape planting. Irregular sampling of T. nigrina at Clemson, South Carolina, and elsewhere in southeastern states suggests that adults overwinter and that at least two annual generations are produced.
