Metarhizium anisopliae: current status and future in hard ticks control in Asia

Abstract

Ticks exert a significant economic impact on the livestock industry, particularly in Asian regions. Presently, chemical acaricides constitute the primary method employed to combat tick infestations in livestock, but their use carries adverse environmental consequences. Overreliance on acaricides has contaminated milk and meat products with chemical residues while fostering tick resistance to these agents due to improper and intensive application. Various alternative methods have been explored, including using vaccines to manage tick populations. However, the efficacy of these treatments varies and is often limited when applied separately. Among these alternatives, entomopathogenic fungi like Metarhizium anisopliae appear to be a promising candidate for tick population control. This fungus can be used independently and in conjunction with other products. This review article explores the current and future prospects of M. anisopliae, where the existing gaps and future directives for using this fungus to control hard ticks in Asian countries are highlighted.
