Confirmation of insecticide resistance in Cimex lectularius Linnaeus (Hemiptera: Cimicidae) in Australia
Austral Entomology 54 (1), 96-99
Abstract: Insecticide resistance in the common bed bug, Cimex lectularius Linnaeus has been suspected in Australia with anecdotal reports of poor product performance. To investigate this possibility, LD₅₀ values were determined via topical application of technical grade permethrin, deltamethrin, bendiocarb, pirimiphos-methyl and imidacloprid serially diluted in acetone to a suspected resistant field-collected strain and a susceptible laboratory strain. All compounds tested against the susceptible strain were efficacious. However, for the field strain, only pirimiphos-methyl and imidacloprid showed high levels of activity. Resistance was confirmed in the field-collected strain to the pyrethroids and bendiocarb, but not to pirimiphos-methyl or imidacloprid. Resistance factors ('resistant' LD₅₀/susceptible LD₅₀) for each compound were: permethrin ~ 1.235 million, deltamethrin ~ 370 000, bendiocarb ~ 250, pirimiphos-methyl = 2.6, imidacloprid = 2.6. Bendiocarb, permethrin and deltamethrin all failed to return greater than 60% mortality at the maximum dose of 100 µg/μL. This research has significant operational implications for bed bug control and the registration process of new products in Australia.
