Field efficacy of triflumuron against Aedes and Culex mosquitoes in temperate Argentina

Aedes aegypti and Culex pipiens s.l. (Linnaeus, 1762 and 1758, respectively) (Diptera: Culicidae) are importantvectors of diseases to humans and a growing public health concern. In order to contribute to the control ofmosquito vectors by low environmental impact approaches we assessed the susceptibility of natural populationsof container-breeding mosquitoes to triflumuron, an insect growth regulator, in temperate Argentina. A field trialwas conducted to evaluate the efficacy of two doses (0.5 ppm and 1 ppm) of triflumuron (SC 48%) againstnatural populations of Ae. aegypti and Culex spp. immatures in flower vases of four cemeteries. The resultsdemonstrated the susceptibility of both target mosquitoes to triflumuron in field conditions. For Ae. aegypti,dose-dependent reductions were achieved in the presence of pupae and the percentage of water-holding containersharbouring L3–4 and/or pupae, whereas the larvae abundance was equally reduced for both doses. ForCulex spp., similar levels of reduction of larvae abundance and pupae presence were achieved with both doses. Significant effects on the response variables measured were recorded up to six to eight weeks post-intervention. Bimonthly applying 1 ppm triflumuron in the context of an integrated mosquito management should achieve alasting control of Ae. aegypti and Culex spp. in small artificial containers with minimal environmental impacts.
