Abstract

A meeting, sponsored by the Bill and Melinda Gates Foundation (BMGF) and organised by Clinglobal, was held at The International Livestock Research Institute (ILRI) in Nairobi, Kenya, from 19th - to 21st October 2022. The meeting assembled a unique group of experts on tick control in Africa. Academia, international agencies (FAO and ILRI), the private Animal Health sector and government veterinary services were represented. The significant outcomes included: (i) a shared commitment to standardisation and improvement of acaricide resistance bioassay protocols, particularly the widely used larval packet test (LPT); (ii) development of novel molecular assays for detecting acaricide resistance; (3) creation of platforms for disseminating acaricide resistance data to farmers, veterinary service providers and veterinary authorities to enable more rational evidence-based control of livestock ticks. Implementation of enhanced control will be facilitated by several recently established networks focused on control of parasites in Africa and globally, whose activities were presented at the meeting. These include a newly launched community of practice on management of livestock ticks, coordinated by FAO, an African module of the World Association for the Advancement of Veterinary Parasitology (WAAVP-AN) and the MAHABA (Managing Animal Health and Acaricides for a Better Africa) initiative of Elanco Animal Health.

Keywords: Acaricide resistance; Amidines (Amitraz), Synthetic pyrethroids, Organophosphates; Larval Packet Test (LPT); Rhipicephalus appendiculatus; Rhipicephalus microplus; Ticks.

Acaricide resistance detection and mitigation strategy. The figure describes the major steps envisaged in the acaricide mitigation strategy. Improvement of existing bioassays and development of PCR-based molecular assays and training of users, surveillance of farming systems for resistant ticks using these tools, feedback of data collected to farmers and other stakeholders and more efficient use of acaricides leading to increased sustainability of livestock production
