Lambda-Xyhalothrin Resistance Detection in the German Cockroach (Blattodea: Blattellidae)

Abstract

Lambda-Cyhalothrin resistance levels of 13 recently collected field strains of German cockroach, Blattella germanica (L.), were determined by topical insecticide bioassay. The resistance levels ranged from 21- to 67-fold. Residual bioassays were conducted simultaneously against the Orlando Insecticide-susceptible strain, the HRDC strain (carbamate resistant), the Village Green Strain (Pyrethroid resistant), and the Marietta strain (pyrethroid, carbamate, and organophosphorus resistant) to determine a diagnostic concentration for use in resistance detection bioassays. The LC99 (4.5 micrograms per jar) were chosen for use in Lambda-cyhalothrin resistance detection bioassays. A highly significant relationship was observed between mortality and 5 times the LC99 of Orlando (4.5 micrograms per jar) and resistance ration (LD50 in topical bioassays). The relevance of this relationship to Lambda-cyhalothrin resistance detection is discussed.
