Assessments of Anopheles arabiensis behaviour around bed nets using partial adhesive treatments

Njelembo J. Mbewe, Salum Azizi, Mark Rowland, Matthew J. Kirby et autres

Understanding the behaviour of malaria vectors could lead to improved designs of partially treated insecticidal nets and low-cost nets with less insecticide content. The behaviour of Anopheles arabiensis around cow baited bed nets with partial adhesive treatments were assessed in experimental huts. …

A noninferiority cluster randomised evaluation of a broflanilide indoor residual spraying insecticide, VECTRON T500, for malaria vector control in Tanzania

Njelembo J. Mbewe, Patrick Tungu, Louisa A. Messenger, John Bradley et autres

Effective malaria vector control is being undermined by the rapid spread of insecticide resistance. VECTRON T500, a new indoor residual spraying (IRS) product containing the active ingredient broflanilide as a 50% wettable powder (WP), was previously shown to be efficacious in experimental …

Level of involvement of four selected cytochrome P450s (CYPs) in pyrethroid-resistant Anopheles gambiae (s.s.) and Anopheles coluzzii across Côte d’Ivoire

Joseph Chabi, Constant V.A. Edi, Bernard L. Kouassi, Constant N. G. Gbalegba et autres

In Côte d'Ivoire, there is a high intensity of pyrethroid resistance in malaria vectors which may threaten successful vector control. Molecular studies of the target site mutation in the voltage-gated sodium channel (VGSC) 1014F show that the gene frequencies of these mutations …

Efficacy of partial spraying of SumiShield, Fludora Fusion and Actellic against wild populations of Anopheles gambiae s.l. in experimental huts in Tiassalé, Côte d'Ivoire

Joseph Chabi, Aklilu Seyoum, Constant V.A. Edi, Bernard L. Kouassi et autres

From August 2020 to June 2021, we assessed the efficacy of SumiShield 50WG (clothianidin), Fludora Fusion 56.25WP-SB (mixture of clothianidin and deltamethrin) and Actellic 300CS (pirimiphos-methyl) in experimental huts when partially sprayed against wild, free-flying populations of Anopheles gambiae s.l. in Tiassalé, …

Laboratory evaluation of broflanilide (TENEBENAL™) against Anopheles gambiae in Moshi, Tanzania – delayed mortality, cross-resistance, and residual efficacy

Janneke Snetselaar, Mark Rowland, Salum Azizi, Benson Mawa et autres

Introduction Broflanilide is a novel meta-diamide insecticide, which has a distinct mode of action compared to other active ingredients used for Indoor Residual Spraying (IRS). This study details a laboratory evaluation of broflanilide, of putative discriminating concentrations, potential cross-resistance, and residual efficacy …

A non-inferiority and GLP-compliant study of broflanilide IRS (VECTRON™ T500), a novel meta-diamide insecticide against Anopheles arabiensis

Njelembo J. Mbewe, Matthew J. Kirby, Janneke Snetselaar, Robert Kaaya et autres

Management of insecticide resistance in vector control requires development and evaluation of active ingredients (AIs) with new modes of action. VECTRON™ T500 is a wettable powder formulation used for Indoor Residual Spraying (IRS) containing 50% of broflanilide as an AI. This study …

A new WHO bottle bioassay method to assess the susceptibility of mosquito vectors to public health insecticides: results from a WHO-coordinated multi-centre study

Vincent Corbel, Mara D. Kont, Martha Liliana Ahumada, Laura Andréo et autres

Abstract Background The continued spread of insecticide resistance in mosquito vectors of malaria and arboviral diseases may lead to operational failure of insecticide-based interventions if resistance is not monitored and managed efficiently. This study aimed to develop and validate a new WHO …

Multi-centre discriminating concentration determination of broflanilide and potential for cross-resistance to other public health insecticides in Anopheles vector populations

Natalie M. Portwood, Magreth Shayo, Patrick Tungu, Njelembo J. Mbewe et autres

Abstract Novel insecticides are urgently needed to control insecticide-resistant populations of Anopheles malaria vectors. Broflanilide acts as a non-competitive antagonist of the gamma-aminobutyric acid receptor and has shown prolonged effectiveness as an indoor residual spraying product (VECTRON T500) in experimental hut trials …
