Resumen

Potato and coffee crops grapple with pronounced challenges posed by pests, notably the Andean potato weevils (Premnotrypes spp.) and the coffee berry borer (Hypothenemus hampei). These pests inflict significant economic repercussions on both smallholder and commercial farmers by disrupting essential food supply chains. This review delves into the insecticidal potentials of botanical resources against these pests. Notably, extracts and essential oils (EOs) from native flora or commercially available in each affected country have compelled efficacy against Premnotrypes vorax, P. latithorax and Hypothenemus hampei, such as Schinus molle L. and Schinus terebinthifolia Raddi, respectively. Through rigorous laboratory tests, on-site evaluations, and cost-effectiveness assessments, there emerges a strong advocacy for these botanical solutions. They present not only a sustainable countermeasure to these pests but also a greener alternative to conventional pesticides, thereby potentially reducing the environmental degradation and health concerns synonymous with chemical pesticides. The shift towards natural pesticides, especially those derived from plants like S. molle and S. terebinthifolia, is not only environmentally strategic but also economically prudent, aligning with both market trends and long-term sustainability goals.
