Abstract:
Insecticidal activities of noviflumuron formulated as dust, gel, and suspension concentrate (SC) were evaluated against the German cockroach, Blattella germanica (L.), in the laboratory and in apartments. In laboratory studies conducted in large cockroach arenas (1 m2 boxes), population reductions averaged 99.9 ± 0.07, 97.7 ± 0.2 and 65.6 ± 16.7% for the dust, gel, and SC, respectively, after 16 weeks of exposure. For flufenoxuron dust, population reductions averaged 98.1 ± 0.2%. There were no significant differences between noviflumuron formulations compared to flufenoxuron. There were significant differences between the population sizes in the noviflumuron treatments compared to the untreated control. Cockroach populations not exposed to toxic baits increased in size by more than 1365.5 ± 69.9%. In a 2-year study conducted in apartments, noviflumuron dust and gel baits gave residual control of German cockroach populations. There were no significant differences between the performances of noviflumuron baits compared to the Maxforce® gel bait, and Avert® 310 dust bait.
