A Systematic Review of Biological Control Agents, Plant Extracts and Cover Crops or Intercropping for the Control of Leucoptera coffeella (Lepidoptera: Lyonetiidae)

The leaf miner Leucoptera coffeella Guérin-Méneville & Perrottet, 1842 (Lepidoptera: Lyonetiidae), is a major pest of coffee plants (Coffea spp.) worldwide. It is recognized for its widespread occurrence in coffee plantations and the quantitative and economic losses it causes to coffee production, especially in regions with higher temperatures and greater water deficits. We evaluated historical and current research approaches to leaf miner management, establishing current knowledge through a systematic review of research on biological control agents (BCAs), plant extracts and cover crops or intercropping for L. coffeella control, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We conducted a systematic review of research findings from 1980 to 2025, developing a set of a priori criteria for subsequent replication of the review process. This review covers 130 publications, of which 28 met the inclusion criteria. The selected studies were conducted in five countries, although 75.00% of the studies were from Brazil. The BCAs accounted for 60.71%, followed by plant extracts (32.17%) and cover crops or intercropping (7.15%). Field studies were predominant, prioritizing diagnostic studies, surveys, studies on alternative control methods, and finally studies on BCAs, providing an effective solution. The limitations and prospects for their management were analyzed, and we highlighted recommendations that will improve future studies.
