Les Loranthaceae constituent des ressources précieuses pour les populations locales africaines. Cependant, peu d’ethnies connaissent l’importance socio-économique des Loranthaceae de par le manque d’études ethnobotaniques sur ces espèces. Afin de contribuer à la valorisation et à la gestion durable des Loranthaceae parasites des plantes ligneuses, une approche associant deux méthodes a été adoptée. L’une, basée sur des relevés de surface et l’autre sur une enquête ethnobotanique relative aux connaissances locales des Loranthaceae dans 9 Arrondissements de la Région de l’Extrême-Nord du Cameroun. Au total, 4 genres (Agelanthus, Globimetula, Phragmanthera et Tapinanthus) et 7 espèces parasites (Agelanthus dodoneifolius, Globimetula braunii, Phragmanthera capitata, Tapinanthus bangwensis, T. belvisii, T. globiferus et T. ophiodes) ont été inventoriés et identifiés dans les Monts Mandara. Il ressort aussi que ces espèces parasites sont utilisées en pharmacopée dans des recettes médicinales et magico-religieuses (45,56%), pour traiter des infertilités (32,70%) et des troubles mentaux (32,36%). Les résultats ont aussi montré que Mangifera indica (35,74%) et Senna singueana (34,41%) sont les hôtes des parasites les plus sollicités. Aussi ont-ils révélé que la commercialisation des Loranthaceae constitue une source de revenu économique et une ressource importante en pharmacopée pour les populations locales des Monts Mandara. Ces résultats pourraient servir de référence pour la recherche de stratégies d’exploitation et de conservation durable de cette diversité végétale.Mots clés : Loranthaceae, Espèces parasites, pharmacopée, Monts Mandara, Cameroun.   English Title: Diversity and socio-economic importance of Loranthaceae parasites of woody plants of Mandara Mountains in the Far-North Region, Cameroon Loranthaceae are valuable resources for local African populations. However, few ethnic groups know the socio-economic importance of Loranthaceae due to the lack of ethnobotanical studies on these species. In order to contribute to the enhancement and sustainable management of Loranthaceae parasites of woody plants, an approach combining two methods was adopted. One, based on surface surveys and the other on an ethnobotanical survey relating to local knowledge of Loranthaceae in 9 Subdivisions of the Far North Region of Cameroon. In total, 4 genera (Agelanthus, Globimetula, Phragmanthera and Tapinanthus) and 7 parasitic species (Agelanthus dodoneifolius, Globimetula braunii, Phragmanthera capitata, Tapinanthus bangwensis, T. belvisii, T. globiferus and T. ophiodes) have been inventoried on the Mandara Mountains. It also appears that these parasitic species are used in pharmacopoeia in medicinal and magico-religious recipes (45.56%), to treat infertility (32.70%) and mental disorders (32.36%). The results also showed that Mangifera indica (35.74%) and Senna singueana (34.41%) are the hosts of most solicited parasites. They also revealed that the commercialisation of Loranthaceae constitutes a source of economic income and an important resource in pharmacopoeia for the local populations of the Mandara Mountains. These results could serve as a reference of strategies for the sustainable exploitation and conservation of this plant diversity.Keywords: Loranthaceae, parasitic species, pharmacopoeia, Mandara mountains, Cameroon.

Maize rayado fino virus (MRFV) causes a severe disease of corn (Zea mays) in many locations throughout the neotropics and as far north as southern U.S. MRFV particles detected by direct electron microscopy of negatively stained sap from infected leaves are not necessarily distinguishable from many other small isometric viruses infecting plants (Fig. 1).Immunosorbent trapping of virus particles on antibody-coated grids and the antibody coating or decoration of trapped virus particles, was used to confirm the identification of MRFV. Antiserum to MRFV was supplied by R. Gamez (Centro de Investigacion en Biologia Celular y Molecular, Universidad de Costa Rica, Ciudad Universitaria, Costa Rica).Virus particles, appearing as a continuous lawn, were trapped on grids coated with MRFV antiserum (Fig. 2-4). In contrast, virus particles were infrequently found on grids not exposed to antiserum or grids coated with normal rabbit serum (similar to Fig. 1). In Fig. 3, the appearance of the virus particles (isometric morphology, 30 nm diameter, stain penetration of some particles, and morphological subunits in other particles) is characteristic of negatively stained MRFV particles. Decoration or coating of these particles with MRFV antiserum confirms their identification as MRFV (Fig. 4).

Abstract. Background: Indigenous Australians experience a suicide rate over twice that of the general population. With nonfatal deliberate self-harm (DSH) being the single most important risk factor for suicide, characterizing the incidence and repetition of DSH in this population is essential. Aims: To investigate the incidence and repetition of DSH in three remote Indigenous communities in Far North Queensland, Australia. Method: DSH presentation data at a primary health-care center in each community were analyzed over a 6-year period from January 1, 2006 to December 31, 2011. Results: A DSH presentation rate of 1,638 per 100,000 population was found within the communities. Rates were higher in age groups 15–24 and 25–34, varied between communities, and were not significantly different between genders; 60% of DSH repetitions occurred within 6 months of an earlier episode. Of the 227 DSH presentations, 32% involved hanging. Limitations: This study was based on a subset of a larger dataset not specifically designed for DSH data collection and assesses the subset of the communities that presented to the primary health-care centers. Conclusion: A dedicated DSH monitoring study is required to provide a better understanding of DSH in these communities and to inform early intervention strategies.

Objetivo: Caracterizar y evaluar las selecciones Ataulfo diamante’, ‘Zafiro’ y ‘Citlalli’ de mango (Mangifera indica L.), obtenidas en el programa de mejoramiento genético de mango en el Campo Experimental Rosario Izapa del INIFAP.Diseño/metodología/aproximación: Se realizó la caracterización morfológica de acuerdo a los descriptores propuestos por la UPOV. Se evaluó el comportamiento agronómico de los clones, y con los resultados de las variables se aplicó un análisis de varianza y una comparación de medias de acuerdo a Tukey con un a=0.05.Resultados: Se encontraron diferencias morfológicas entre los clones caracterizados y evaluados; las diferencias fueron en morfología del fruto, sabor y rendimiento.Limitaciones del estudio/implicaciones: El potencial productivo y la calidad de los clones de mango estará en función del manejo en campo y postcosecha que reciban los frutos.Hallazgos/conclusiones: Los clones ‘Citlalli’, ‘Ataulfo Diamante’ y ‘Ataulfo Elite’ presentan características productivas de alto potencial y registran calidad para ser considerados en programas de mejora de la productividad del cultivo en la región del Soconusco, Chiapas, México.
