Control failure risk, resistance and enzymatic activity of neurotoxic insecticides in Brazilian populations of Leucoptera coffeella (Lepidoptera: Lyonetiidae)

open access: yesPest Management Science, Volume 82, Issue 6, Page 5757-5766, June 2026.
Bioassays of 36 Leucoptera coffeella populations revealed resistance to neurotoxic insecticides, control failures of ≤62.9% and enzyme activity variation, with particularly high GST and low AChE levels. Abstract Background Leucoptera coffeella is a key pest of coffee crops in Brazil, causing significant damage by mining coffee leaves.

Intraspecific trait variation and coordination: Root and leaf economics spectra in coffee across environmental gradients [PDF]

open access: yes, 2017
Hypotheses on the existence of a universal “Root Economics Spectrum” (RES) have received arguably the least attention of all trait spectra, despite the key role root trait variation plays in resource acquisition potential.

Genome association of carbohydrate metabolites provides new insights toward functional breeding in coffee

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Coffee is one of the world's most widely consumed beverages, derived mainly from Coffea arabica, known for its superior flavor, and Coffea canephora (Robusta/Conilon), valued for its resilience and higher caffeine content. Functional breeding aims to develop cultivars that combine productivity and stress tolerance with improved health‐related ...

Effect of Dormancy Treatment on Germination of Arabica Coffee ( Coffea arabica L.)

open access: yesJURNAL AGROTEKNOLOGI, 2022
The germination process of arabica coffee bean takes a fairly longtime, due to semi-permeable skin against water. Dormancy treatment needs to improve germination rate of coffee beans before planting. The research was conducted at The Compost Centre of Agriculture Faculty, University of Sumatera Utara from July – September 2018 using a Randomized ...

Evaluation of in vitro toxicity of common phytochemicals included in weight loss supplements using 1H NMR spectroscopy

open access: yesFEBS Open Bio, Volume 16, Issue 5, Page 906-920, May 2026.
We investigated the toxicity of 12 active compounds commonly found in herbal weight loss supplements (WLS) using human liver and colon cell models. Epigallocatechin‐3‐gallate was the only compound showing significant toxicity. Metabolic profiling revealed protein degradation, disrupted energy and lipid metabolism suggesting that the inclusion of EGCG ...
