- Insecticidal Efficacy of Broflanilide against German Cockroach, <i>Blattella germanica</i> (Dictyoptera: Blattellidae): Field and Laboratory Evaluations
抄録
<p>A new insecticide formulation of broflanilide (VECTRON FL) is expected to be effective against insecticide-resistant German cockroaches. In the current study, the efficacy of broflanilide was tested in the field and laboratory. A single application of broflanilide at 50 mg (ai)/m2 in a restaurant led to complete extermination by 6 weeks post-treatment. Broflanilide applied to plywood killed 100% of organophosphorus- and pyrethroid-resistant colonies in a 6 h contact test. In addition, the residual activity of broflanilide was maintained for 92 days on permeable plywood at 50 mg/m2 and nonpermeable plywood at 25 mg/m2, whereas that of fenitrothion was reduced at 92 days post-treatment. Broflanilide was also highly lethal in 10 and 60 min contact tests against resistant colonies. Moreover, when cockroaches exposed for 10 or 60 min to a surface residue of broflanilide were mixed with unexposed cockroaches, >50% of the unexposed cockroaches died by day 8. Thus, broflanilide performs well against directly exposed cockroaches and the unexposed cockroaches they encounter in hiding places. In conclusion, even if atomized particles of the chemical solution do not reach deeply into the crevices of the kitchens in the restaurants, a single treatment of broflanilide exhibits high extermination efficacy.</p>
