Association of Agro‐Morphological Traits With Cup Quality in Accessions of Coffea arabica L. From the INIA Germplasm Bank, Peru

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT In recent years, Peruvian coffee production has increasingly focused on specialty coffees, with cup quality (CQ) as a key criterion. While previous studies have characterized the Coffee Germplasm Collection of the National Institute of Agrarian Innovation (CGC‐INIA), few studies have analyzed coffee cup quality.

Leaf Extracts of Coffea racemosa Inhibit Trypsin Activity and Affect Larval Development in Spodoptera frugiperda and Diatraea saccharalis

Entomologia Experimentalis et Applicata, Volume 174, Issue 6, Page 527-535, June 2026.
Leaf extracts of Coffea racemosa inhibit digestive trypsins and impair the development of two major lepidopteran pests, Spodoptera frugiperda and Diatraea saccharalis. While both species showed significant enzymatic inhibition, biological responses differed markedly. D. saccharalis exhibited high mortality, whereas S.

Thermal sensitivity and yield of Arabica coffee under climatic variability

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Coffee yield is influenced by climatic factors, with temperature and water availability being key determinants. This study aimed to evaluate the effects of climate variability on the yield of Arabica coffee (Coffea arabica L.) cultivars across phenological phases and to validate an agrometeorological model at local and regional scales using ...

Spray deposition and chemical control of the coffee leaf-miner with different spray nozzles and auxiliary boom [PDF]

Engenharia Agrícola, 2016
The coffee crop requires great spray ability to penetrate into the plant canopy during the application of pesticides. The aim of this study was to evaluate the spray deposition on leaves of coffee plants and the chemical control of the leaf miner ...

Diversity of Hymenopteran Parasitoids in Coffee Plantations under Agroecological Transition and Its Impact on Coffee Leaf Miner (Leucoptera coffeella) Infestations

Diversity, 2022
The biodiversity of natural competitors is vital to key ecosystem services and agroecosystems’ benefits to society. The abundance and richness of hymenopteran parasitoid communities, and subsequently their services, are dependent on the variety of ...

New records and new species of Miracinae (Hymenoptera: Braconidae) from Australia and Papua New Guinea, with a key to world Mirax species

Austral Entomology, Volume 65, Issue 1, February 2026.
Abstract The genera of Miracinae, currently in something of a state of flux, are discussed with respect to their morphological and molecular attributes. Centistidea Rohwer, 1914 is treated provisionally as a valid genus, distinct from Mirax Haliday, 1833, based partly on propodeal morphology, though this is acknowledged to be an unstable character ...

Toxicity of organic farming‑compatible products to the coffee leaf miner Toxicidade de produtos compatíveis com a agricultura orgânica ao bicho‑mineiro do cafeeiro

Pesquisa Agropecuária Brasileira, 2013
The objective of this work was to evaluate the toxicity of organic farming‑compatible products to the coffee leaf miner Leucoptera coffeella. Lime sulphur, enriched Bordeaux mixture (Viça Café Plus), and the "supermagro" biofertilizer were first ...
