Abstract: Citrus leprosis (CL) severely threatens citrus production, particularly in Brazil, where it has inflicted significant economic losses. This disease is caused by a viral complex transmitted by mites of the genus Brevipalpus, known as flat mites or false spider mites. CL symptoms include chlorotic or necrotic lesions on leaves, stems, and fruits, often leading to defoliation, premature fruit drop, and tree dieback. Due to the non-systemic nature of CL pathogens, lesions remain restricted to the virus inoculation loci. Despite this, a widespread infection can lead to total crop losses if mite populations are not controlled. The CL viral complex consists of viruses of the genera Cilevirus and Dichorhavirus and some of these viruses can affect both citrus and non-citrus plants. The primary causal agents include citrus leprosis virus C (CiLV-C, Cilevirus leprosis) and C2 (CiLV-C2, Cilevirus colombiaense), transmitted by Brevipalpus yothersi mites, and orchid fleck virus (OFV, Dichorhavirus orchidaceae) transmitted by B. californicus. The CL management is multifaceted and focused on acaricides, which is a challenging task due to the mites’ polyphagous nature, the presence of resistant subpopulations, and mite ability to adapt to environmental conditions. CL prevention is further difficulted by global trade, which may facilitate the spread of viruliferous mites and infected plant materials. Ornamental plants have emerged as critical reservoir hosts for CLassociated viruses, facilitating their spread to citrus crops. Research continues to explore sustainable management strategies, but until more effective solutions are found, CL remains a substantial agricultural and economic threat to citrus-producing regions.
