Popis:	The native Australian broad-leaved paperbark tree, Melaleuca quinquenervia, is a major weed in southern Florida. Among the potential biological control agents studied for this weed is a coreid bug, Pomponatius typicus, whose adults and nymphs feed on the sap of young, fresh growing tips, causing wilting. Female P. typicus may lay 31 or more eggs. The nymphs emerge after 11–13 days and pass through five instars in approximately 2 months. Adults live for 4 months or more, and have been observed to enter an apparent diapause for up to 2 months. Parasites have been reared only from its eggs. Results of laboratory and field host-range studies indicate that this bug is restricted to Melaleuca spp., especially the Melaleuca leucadendra complex to which M. quinquenervia belongs, and Callistemon spp. (especially Callistemon viminalis). As C. viminalis is of only minor importance as an introduced ornamental in Florida and is also considered a weed, P. typicus was approved in 1996 for further studies in quarantine in the USA.
