The CABANA project (Capacity Building for Bioinformatics in Latin America) was funded by the UK's Global Challenges Research Fund in 2017 with the aim to strengthen the bioinformatics capacity and extend its applications in Latin America focused on three challenge areas - communicable diseases, sustainable food production and protection of biodiversity. For 5 years, the project executed activities including data analysis workshops, train-the-trainer workshops, secondments, eLearning development, knowledge exchange meetings, and research projects in 10 countries. The project was successful in accomplishing all its goals with a major impact on the region.

Coffee berry disease is caused by , a quarantine fungus still absent from most coffee-producing countries. Given the potential adverse effects on coffee berry production, it is a severe worldwide threat to farmers and industry. Current biosecurity management focuses on exclusion by applying quarantine measures, including the certification of coffee plants and their products.

Despite the important role that flower-visiting insects play in agricultural production, none of the previous studies of coffee pollinators in Colombia have incorporated functional diversity into their analysis. Therefore, this study aimed to quantify the abundance, richness, and functional diversity of insects that visit flowers in coffee crops. Twenty-eight plots were selected among five sites in the north, center, and south of Colombia.

The coffee berry borer (CBB), (Ferrari, 1867) (Coleoptera: Curculionidae: Scolytinae), native to Africa, is a major global insect pest of coffee. It has invaded many coffee production areas around the world that do not have natural enemies. In this study, two African parasitoids, Waterston (Hymenoptera: Bethylidae) and Waterston (Hymenoptera: Eulophidae), were mass-reared for field release against in Chinchiná, Colombia.

In coffee (Coffea arabica L.), male sterility is a prerequisite for the exploitation of heterosis since it provides an efficient and reliable method for the production of hybrid seeds. Given its relevance, the objective of this study was to identify male-sterile genotypes within the Colombian Coffee Collection that can be used in genetic improvement.

Prior to recommending insecticides to treat the coffee berry borer (CBB) Hypothenemus hampei, it is valuable to know the mortality and repellency of these insecticides against adult insects or their impact on reproductive output. However, currently available methods assess adult mortality only, limiting the selection of novel insecticides with a different mode of action. In this work, different experimental methods were examined to identify the diverse effects on the CBB under laboratory conditions.

Article Synopsis
  • The coffee berry borer (CBB) is the main pest affecting coffee crops and hosts diverse bacteria that may impact its nutrition and immunity.
  • Researchers used high-throughput sequencing to analyze the gut bacteria across different CBB life stages, identifying 15 bacterial phyla and various genera that populate the gut.
  • The study found significant diversity in the gut microbiota, with some bacterial species consistently present in all life stages, providing insights that could lead to improved pest control methods for CBB.

During coffee harvest, picked berries fall to the ground where they serve as a reservoir for the coffee berry borer (CBB) which then infest coffee berries on the trees. This study tested the effect of fallen CBB-infested coffee berries on the infestation of coffee trees (Coffea arabica). Three-year-old trees were treated with either 0, 1, 5, 10, 15, or 20 CBB-infested berries placed on the root vicinity.

Coffee berry borer-CBB (Hypothenemus hampei) is a globally important economic pest of coffee (Coffea spp.). Despite current insect control methods for managing CBB, development of future control strategies requires a better understanding of its biology and interaction with its host plant.

The coffee berry borer (CBB) is one of the main coffee pests in the world including Colombia. This pest is difficult to manage because of its cryptic habits and the continuous availability of coffee fruits. Among the new management strategies being tested is the use of volatile compounds as insect repellents.

In this paper we have characterized the lineage of two traits associated with the coat proteins (CPs) of the tombusvirids: Silencing suppression and HR elicitation in species. We considered that the tombusvirid CPs might collectively be considered an effector, with the CP of each CP-encoding species comprising a structural variant within the family. Thus, a phylogenetic analysis of the CP could provide insight into the evolution of a pathogen effector.

Coffee culture, one of the main agricultural activities in Brazil, has undergone recent negative impacts due to unfavorable climate conditions, with a subnormal rainy period and increased temperatures during the second half of 2015. The coffee berry borer Hypothenemus hampei (Ferrari, 1867) (Coleoptera: Curculionidae) is one of the main insect pests of coffee crops worldwide. The present research aimed to determine the climate zones for coffee berry borer in the state of São Paulo, based on its thermal requirements.

Article Synopsis
  • The coffee berry borer (CBB) is a major pest impacting global coffee production, and its genome has recently been sequenced, revealing information on transposable elements (TEs) for the first time.
  • A newly created library identified 880 TEs, with 66% being Class I (LTRs and non-LTRs) and 34% Class II (various DNA transposons), including newly proposed families like Hypo, Hamp, and rosa.
  • Although TEs make up about 8.2% of the CBB genome, the majority are degenerate, with MITEs representing about 50% of TEs, indicating a high diversity but low presence of full-length copies.

In this study, the lignocellulosic residue coffee pulp was used as carbon source in fermentative l(+)-lactic acid production using Bacillus coagulans. After thermo-chemical treatment at 121°C for 30min in presence of 0.18molL(-1) H2SO4 and following an enzymatic digestion using Accellerase 1500 carbon-rich hydrolysates were obtained.

In this study, mucilage, a residue from coffee production, was investigated as substrate in fermentative l(+)-lactic acid production. Mucilage was provided as liquid suspension consisting glucose, galactose, fructose, xylose and sucrose as free sugars (up to 60gL(-1)), and used directly as medium in Bacillus coagulans batch fermentations carried out at 2 and 50L scales. Using mucilage and 5gL(-1) yeast extract as additional nitrogen source, more than 40gL(-1) lactic acid was obtained.

The coffee berry borer Hypothenemus hampei is a pest that causes great economic damage to coffee grains worldwide. Because the proteins consumed are digested by aspartic proteases in the insect's midgut, the inhibition of these proteases by transferring a gene encoding an aspartic protease inhibitor from Lupinus bogotensis Benth. to coffee plants could provide a promising strategy to control this pest.
