Behavioral resistance of field-collected German cockroaches (Blattodea: Blattellidae) to baits containing glucose
Environmental Entomology 23 (2), 425-430
Abstract: German cockroaches, Blattella germanica (L.), collected from a number of field locations, ranging from Florida to South Korea, displayed an avoidance behavior to a bait formulation. Cockroaches collected from locations that had a history of treatment with this formulation demonstrated bait avoidance, whereas laboratory and field strains with no prior exposure ingested and were susceptible to the toxic bait. Thus, behavioral resistance had evolved in these insects. Selection experiments showed that several susceptible strains were potentially capable of developing behavioral resistance. Strains that avoided ingesting bait also displayed an aversion to glucose, which is a component of the bait that is typically phagostimulatory. Substitution of fructose for glucose in toxic baits significantly improved bait efficacy.
