This study investigated the dynamics in pyrethriod resistance and the presence/frequencies of L1014F knockdown resistance mutant allelles in Culex quinquefasciatus vector populations from Uruan Local Government Area of AkwaIbom State, Southern Nigeria between the months of March and November, 2021. Uruan LGA is among the endemic LGAs for lymphatic filariasis in AkwaIbomState. Female Anopheles mosquitoes from Eman Uruan, Ituk Mbang and Idu Uruan were exposed to permethrin, deltamethrin and alphacypermethrin in CDC insecticide coated bottles for susceptibility bioassay following standard protocols.

Article Synopsis
  • Onchocerciasis, a parasitic disease spread by black flies, significantly impacts public health and the economy in Nigeria, but control efforts like Mass Drug Administration of ivermectin have reduced its prevalence.
  • The study focused on understanding transmission dynamics in Cross River State after two decades of ivermectin distribution, analyzing factors like infectivity and biting rates in four selected endemic communities.
  • Findings showed significant differences in fly abundance, biting rates, and seasonal activity patterns across the communities, indicating that transmission dynamics may vary throughout the year and among different areas.
