Abstract

The efficacy of disquet and gel superabsorbent polymer-based bait formulations of the organophosphate chlorpyrifos or the insect growth regulator pyriproxyfen or both was evaluated against German cockroaches (Blattella germanica) in a series of laboratory trials. Results of bioassays against German cockroaches with single- and joint-action bait compositions of chlorpyrifos or pyriproxyfen or both indicated that agglomerated disquet or hydrogel insecticide-bait formulations could provide long-term control of nymphs or adults. The data suggested that joint-action disquets could provide simultaneous control of mixed populations of nymphs and adults. The concentration of bait/inert ingredients in a disquet or gel formulation was observed to affect insecticide delivery profiles.
