An emerging Platynota sp. (Lepidoptera: Tortricidae) infesting blueberry (Vaccinium corymbosum) in the central coast of Peru
(Frontiers Media S.A., 2025-06-13) Velasquez Ochoa, Edwin Ricardo; Leiva, Ana María; Gil Ordóñez, Alejandra; Perez Fuentes, Lady Susan; Domínguez, Viviana; Cuellar, Wilmer J.
Blueberry cultivation has recently become a rapidly expanding export industry in Peru. With few to no official records of phytosanitary problems up to date. Nevertheless, as observed in other major blueberry producer countries, pests occurrences have been already reported. This study presents a comprehensive biological and molecular characterization of a novel blueberry pest, identifying it as a member of the Tortricidae family in the genus Platynota. The insect’s average life cycle was determined to be 46.3 days for males and 48.6 days for females, with the larval stage being the longest (25.4 days on average), and the most destructive due to its feeding behavior, which significantly damages buds and fruits. Morphological analysis of the genitalia, along with a comparison of its complete mitochondrial DNA, further supports the conclusion that this pest is a new species. These findings represent the first report of a tortricid pest affecting blueberries in Peru and offer crucial insights for developing effective pest management strategies, contributing to the sustainable growth of blueberry production and exports in the region

Development and phenotypic characterization of a native Theobroma cacao L. germplasm bank from the Loreto region of the Peruvian Amazon: Implications for ex situ conservation and genetic improvement
(Frontiers Media S.A., 2025-06-16) Imán Correa, Sixto Alfredo; Samanamud, Angelo F.; Ramírez , José F.; Cobos, Marianela; Paredes, Cleydi; Castro, Juan C.
Introduction: The ex situ conservation and characterization of native Theobroma cacao L. genetic resources are critical for sustainable cacao production and breeding programs in the face of climate change and escalating disease pressures. This study aimed to establish and characterize a novel germplasm bank from the Loreto region of the Peruvian Amazon, a key center of cacao diversity. Methods: We collected 140 native cacao accessions across 15 river basins in eight provinces of the Loreto region. Accessions were propagated using optimized grafting techniques with IMC 67 rootstock. Phenotypic evaluation was conducted on 402 plants using 36 standardized descriptors (25 quantitative and 11 qualitative). Data analysis included multivariate analysis using Uniform Manifold Approximation and Projection (UMAP) and Shannon-Weaver diversity indices to assess morphological diversity patterns. Results: Grafting achieved 100% survival rate, establishing a comprehensive germplasm bank. Phenotypic characterization revealed exceptional morphological diversity, with quantitative traits exhibiting substantial variation, particularly in fruit characteristics (CV = 15.82–50.82%) and pod index (CV = 144.82%). Multivariate analysis identified five distinct phenotypic groups, with reproductive traits showing stronger differentiation than vegetative traits. Shannon-Weaver diversity indices highlighted high overall phenotypic diversity (H' ≈ 0.7), with seed longitudinal shape and fruit apex form displaying the highest trait-specific diversity (H' > 1.0). Conclusion: This comprehensive characterization establishes a foundation for future multiomics studies and advanced breeding strategies. The documented diversity offers opportunities to leverage CRISPR-Cas-based editing and omics technologies to develop climate-resilient, high-yielding cacao varieties with superior quality traits, contributing significantly to global cacao conservation and improvement programs.
Evaluación del compostaje de alperujo con diferentes concentraciones y el impacto del uso de geomembrana
(Centro de Estudios Transdisciplinarios Bolivia (CET-Bolivia), 2025-05-01) Cahui Azorza, Francisco Antonio; Lloclla Chirinos, Ashly; Roque Ramirez, Luis Miguel; Valenzuela Antezana, Ricardo Nahuel
El estudio evaluó el compostaje de alperujo, un subproducto de la producción de aceite de oliva, en combinación con rastrojos de poda de olivo y estiércol de ovino, bajo condiciones climáticas de Tacna, Perú, entre marzo y septiembre de 2023. Se formularon tres mezclas de compost y se analizó el impacto del uso de geomembranas en el proceso, el cual tuvo una duración de seis meses. Los resultados indicaron que el pH del compost osciló entre 6.3 y 7.4, un rango óptimo para la disponibilidad de nutrientes. La conductividad eléctrica varió entre 0.71 dS/m y 1.98 dS/m, evidenciando que el uso de geomembranas influyó en la salinidad del compost final. Asimismo, la aplicación de geomembranas favoreció una mayor retención de carbono orgánico y nutrientes esenciales, reduciendo la lixiviación y mejorando la estabilidad del compost. Estos hallazgos resaltan la importancia del manejo de pH y salinidad en el compostaje, así como el potencial del alperujo como enmienda orgánica para suelos agrícolas. En conclusión, el uso de geomembranas en el compostaje de alperujo representa una estrategia viable para optimizar la calidad del compost y fomentar prácticas agrícolas sostenibles
Challenges of organic amendments: Impact of vermicompost leachate and biochar on popcorn maize in saline soil

Organic amendments offer a sustainable strategy to enhance soil quality in degraded environments, while also contribute to reducing greenhouse gas generation and implementing a green economy. This study evaluated the comparative effects of two organic amendments— vermicompost leachate and biochar—on the performance of Popcorn maize (Zea mays L. var. everta) grown under saline soil conditions. Four treatments were tested: T0 (Control), T1 (Vermicompost leachate), T2 (Biochar), and T3 (Vermicompost leachate + Biochar), each with 10 replicates arranged in a Completely Random Design (CRD). Although several soil physicochemical, microbiological, and agronomic parameters showed no significant differences compared to the control, biochar application led to notable improvements in soil total organic carbon, microbial community (mesophilic aerobes bacteria, molds, and yeasts), and increased seed length and diameter. In contrast, vermicompost leachate alone had a detrimental effect on plant growth, including reduced leaf area, stem thickness, and grain yield. Notably, grain yield declined by 46% with leachate alone and by 31% when combined with biochar, compared to the control. These results highlight the superior performance of biochar over vermicompost leachate as a soil amendment under saline conditions and underscore the potential risks of broadly applying compost teas in stressed soils. Site-specific assessments and screening for phytotoxins and phytopathogens are recommended before use. Furthermore, the combined use of leachate and biochar may not be advisable under the tested soil characteristics.

The use of organic effluents from livestock farming as biofertilizers for agriculture represents a viable solution for the management of swine waste. The research aimed to evaluate the effect of swine liquid effluent on the growth of hybrid corn for forage purposes. A pot experiment was designed to determine the effect of liquid effluent applications of treatments 21 days after planting. The biofertilizer treatments applied to the irrigation water in the pots were 0.00 (control), 9.45, 18.90, 28.35, 37.80 and 47.25 m3 ha-1. Applications of 37.80 and 47.25 m3 ha-1 improved stem diameter, foliage, and total fresh weight. For root fresh weight and root volume, the highest values occurred with applications of 18.90 to 47.25 m3 ha-1. The nutrient content (N, P, K) of corn treated with swine liquid effluent showed an incremental trend in foliage and roots, as well as the absorption of macronutrients due to the effect of the treatments. Liquid swine effluent showed a promising role as an organic fertilizer for the cultivation of maize for forage purposes, promoting higher biomass production and macronutrient uptake.
