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

open access: yesPest Management Science, EarlyView.
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.

Cross‐Species Reprogramming of Developmental Plasticity and Metabolic Rewiring via Banana‐Derived WUS2 Developmental Regulator

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Plant regeneration is governed by intrinsic gene regulation and phytohormonal cues. WUSCHEL (WUS) gene promotes regeneration, but its broader functional role remains unexplored. Here, we demonstrate that the constitutive and inducible expression of banana‐derived WUS2 (GN‐WUS2) enhances regeneration in Nicotiana tabacum (tobacco) and Musa ...

Potential distribution and susceptibility of Coffea arabica L. to climate change impacts

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 693-711, March 2026.
Ecological niche models (ENMs) are vital for understanding the impact of historical factors on ecosystems and predicting future climate change scenarios. These models help assess how environmental shifts affect agricultural species like coffee, which supports millions of people globally.

Are crop yields limited by pollinators? Proper assessments using pollinator gradients require measurements of flower density and yield potential

open access: yesFunctional Ecology, Volume 40, Issue 3, Page 563-569, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract It is widely documented that many crops depend on animal—and primarily insect—pollination, but the degree to which pollinators limit yield in comparison with other factors is poorly understood.

Effect of land use change on Melolonthidae (Coleoptera: Scarabaeoidea) beetle communities in the deforestation arc of the Brazilian Amazon

open access: yesInsect Conservation and Diversity, Volume 19, Issue 2, Page 404-419, March 2026.
Habitat transformation in Amazon due to agriculture expansion impairs Melolonthidae diversity. Assemblage response towards habitat transformation are group‐dependent. Although highly disturbed, Amazon arc of deforestation region dwells sensitive insect assemblages. Abstract Although the Amazon provides crucial goods and ecosystem services for humanity,

Le caféier, Coffea canephora [PDF]

open access: yes, 1999
#Coffea canephora# possède l'une des aires de répartition les plus larges du sous-genre #Coffea# : elle s'étend d'ouest en est, de la Guinée au Soudan et, du nord au sud, du Cameroun à l'Angola. La conservation à long terme de cette espèce s'effectue en champs à cause du comportement peu orthodoxe de ses graines lors de leur stockage.

Geographic provenance and environmental growing conditions as factors influencing phytochemical composition of Arabica green coffee beans

open access: yesPlant Biology, Volume 28, Issue 2, Page 520-534, March 2026.
Growth environment strongly influences green coffee bean biochemistry, linking phytochemical composition to adaptation under abiotic stress. Abstract This study explores how bioactive compounds in green coffee beans (Coffea arabica L.) vary across different geographic regions, addressing the key question of how environmental factors shape coffee ...
