Efficacy of abamectin fed to German cockroaches (Dictyoptera: Blattellidae) resistant to pyrethroids.

摘要: Ten field-collected strains of the German cockroach, Blattella germanica (L.), with varying levels pyrethroid resistance were tested for possible cross-resistance to abamectin administered as a bait. The time-mortality method was used comparison response known susceptible strain in 10-d feeding experiments. Essentially no found. Extensive inhibition occurred after few days, but amount consumed varied substantially from strain. Abamectin may have considerable potential cockroach bait insecticide.
