Residual activity of Phantom PI II for control of bed bugs (Cimex lectularius L.) on different surface types

Bed bug mortality was quantified when confined on fresh (24 hours old) and aged residues (1 month old, 3 months old and 6 months old) of Phantom PII applied on different surface types. For the fresh residue assay, groups of adult bed bugs (50% male: 50% female) were confined on either mattress ticking, sheet metal, or hardboard panels (7cm²) that had been treated at the label rate.  Mortality was recorded at regular intervals until it reached 100%, or for 14 days. For the aged residue assay, groups of adult bed bugs (50% male: 50% female) were confined on surfaces that had been treated at the label rate and then aged for either 1 month, 3 months or 6 months. Mortality was recorded as described above.  For both tests, the control surfaces were treated with water only. Each substrate type had five replications.
