Abstract

Leaf-cutting ants (LCAs) are abundant and cause considerable damage to agricultural and forest crops in the Neotropical region, and are commonly controlled using sulfluramid-based ant baits. However, this active ingredient is a precursor of perfluorooctane sulfonic acid (PFOS), a persistent, human-made pollutant that poses serious environmental and health risks. Several studies have highlighted more natural alternatives to conventional pesticides as a strategic approach for safer management.

In this context, the aim of the present study was to conduct a review through scientific, technological, and molecular mapping of the main plant species and their major compounds used in the alternative control of LCAs using plant essential oils (PEOs).

Seven plant families used for the extraction of PEOs were identified: Aristolochiaceae, Euphorbiaceae, Lamiaceae, Myrtaceae, Piperaceae, Verbenaceae, and Winteraceae. Additionally, 28 patents related to the use of PEOs against pest insects, including LCAs, were identified. Although Brazil has the highest number of scientific publications on this topic, the number of registered patents does not follow the same trend.

This review emphasizes the need to translate scientific knowledge into technological solutions to make alternative products available for the control of LCAs. This is essential to uphold the commitment made under the Stockholm Convention, which seeks to eliminate or restrict the use of Persistent Organic Pollutants.
