Objective: To evaluate three proportions of alcohol in traps with one and three windows and two different colors to capture Hypothenemus hampei Ferrari in Coffea arabica L. plants. Design/methodology/approach: The experiment followed a completely randomized design with a complete factorial arrangement and four replications. From March to July 2007, three mixtures of ethyl: methyl alcohol were evaluated in different proportions (1: 0, 0: 1 and 1: 1). In addition, green and transparent traps were used, designed with a single or three windows. The number of captured coffee berry borers, water loss, attractant evaporation and damaged fruits percentage was evaluated. The data were analyzed through an analysis of variance and a test of means differences (Tukey, p ? 0.05). Results: The mixture of ethyl: methyl alcohol 1: 1 was the best, with an average catch of 980 trapped - insects week-1. The single window of transparent color traps was the most efficient to avoid water loss, with an average loss of 1,129.79 mL and 905 mL respectively. Limitations on study/implications: The design and color of the traps did not influence the capture efficiency and the evaporation of the attractant during the evaluated months. Therefore, it should be further evaluated during other important phenological stages for the crop. Findings/conclusions: Transparent color traps with a window and 1: 1 ethyl: methyl alcohol were efficient for capturing H. hampei and lowering their population.

One of the propagation technique for coffee plant production is tissue culture. Tissue culture technique for Coffea arabica L. faces some problems, mainly in the planlet formation regenerated from explants. The objective of this experiment was to examine the effect 2,4-D and 2-ip combination on the formation of direct somatic embryogenesis of Coffea arabica L. in leaves explant. Auxin (2,4-D) and cytokinin (2-ip) concentrations of, respectively, 1; 5 µM and 5; 10; 15; 20 were used as treatments. This research was conducted using completely randomized design with 10 replications. Observation to induce somatic embryos was done by quantitatively on number of callus from explant and number of embryogenic callus. Beside that, observation by qualitative descriptive was also done on deve lopment of embryogenesis. The results showed that Arabica coffee leaves explant of AS 2K clones could be induced in all medium combination except 5µM 2,4-D and 20µM 2-ip combination. Arabica coffee leaves explant of S 795, Sigararutang and AS 1 varieties could be induced in all medium combination. The highest frequency of callus formation was found in AS 2K, Sigararutang and AS 1 varieties on medium containing 1µM 2,4-D in combination with 10µM 2-ip, whereas for the S 795 variety on medium containing 5µM 2,4-D in combination with 10µM 2-ip. The highest frequency of embriogenic callus in all Arabica coffee variety could be reached on medium containing 5µM 2,4-D in combination with 15µM 2-ip. Key words : Coffea arabica L., somatic embryogenesis, 2,4-D, 2-ip, tissue culture, leaves, callus embryogenic.

Coffea Arabica L

El café (Coffea arabica L.) es de mucha importancia para Nicaragua, tanto económica, como social y ambiental, representando aproximadamente el 25% de las exportaciones. La caficultura es considerada una de las principales fuentes de empleo, alcanzando 63% en las zonas rurales y alrededor del 14% a nivel nacional. El cultivo de café es vulnerable a plagas artrópodas y agentes microbiológicos que afectan hojas, tallos, raíces y frutos, causando pérdidas en los rendimientos. La broca del fruto del café (Hypothenemus hampei, Ferrari) (Coleoptera: Curculionidae) es el principal insecto plaga del café en el país por su daño causado y los elevados costos económicos destinados en su manejo. Siguiendo en importancia, la cochinilla (Planococcus spp) (Hemiptera: Pseudococcidae), que infesta brotes foliares y florales, en infestaciones severas, causa amarillamiento de hojas, marchitamiento de yemas y aborto de frutos. Finalmente, las escamas (Coccus viridis, Green) (Hemiptera: Coccidae), insectos con amplio rango de distribución y abundantes en época seca, causan pérdidas por vigor, enanismo y reducción del número de frutos por planta. Este estudio, tuvo el propósito de contribuir al manejo de plagas del café a través de la evaluación de insecticidas químicos, botánicos y biológicos. Las variables evaluadas fueron, número de frutos brocados y número de escamas y cochinillas por planta. Los resultados indican que los mejores insecticidas para el manejo de broca del café, escamas y cochinillas fueron Galil seguido de Cormoran y Ecobiol, los cuales fueron, además, los tratamientos más rentables

An age-mass structured multi-year tritrophic simulation model of the coffee (Coffea arabica var. mundo novo) - coffee berry borer [Hypothenemus hampei (Ferrari)], borer - three parasitoid system was developed. Three years of extensive plant drymatter data and one year of field data on borer dynamics were collected at Londrina, PR, Brazil. The allometric relationships and parameter for plant drymatter allocation were estimated from the field data, but the parameters for borer and its three parasitoids were summarized from the literature. Initial levels of soil factors (e.g., nitrogen and water) and observed weather data were used to drive the model. The model is largely independent of the field data, yet it simulated the dynamics of plant branching, fruiting and drymatter growth of plant subunits. Simulation results suggest that of the three parasitoids commonly introduced to control the borer, only the eulophid adult endo-parasitoid (Phymastichus coffea La Salle) has the demographic characteristics to potentially regulate borer populations. The effects of harvesting, cleanup of abscised berries, inundative releases of parasitoids and pesticides with various toxicity and persistence characteristics on borer dynamics were evaluated. The model is very flexible, and may provide a sound foundation for incorporating new findings, new varieties, and the biology of new natural enemies worldwide

AbstractEmergence of coffee berry borer, Hypothenemus hampei (Ferrari), from infested coffee berries (Coffea arabica) was studied in the laboratory under controlled temperature and relative humidity (RH) regimes. Low humidities (<60% RH, 25°C) provoked rapid evacuation of adults. Emergence was at a minimum at 90% RH. A steady increase in emergence occurred at values from 90 to 100% RH. Emergence was low below 20°C (90 and 100% RH) and increased markedly between 20 and 25°C. There was no significant increase in emergence above 25°C. Using a simple flight event recorder, emergence flight times were found to peak at the time of maximum daily ambient temperatures on successive days. Under constant temperature conditions successive peaks of emergence were not seen. Results are discussed in relation to control and sampling procedures.

La producción de café en Nicaragua se encuentra en pequeños, medianos y grandes productores provenientes en su mayoría de la región norte central y noroeste del país. El objetivo de esta investigación fue caracterizar sistemas de café desde la perspectiva socioeconómica, agronómica (fitosanitario) y beneficiado húmedo (manejo de cosecha) mediante la ejecución de encuesta a caficultores. Basado en los resultados, se realizó análisis de datos. Los resultados obtenidos fueron los siguientes; el 84 % de los caficultores corresponden al sexo masculino, las edades están comprendidas en los 30 y 79 años, siendo los de 40 y 49 años los más representados (36 %). El 96 % de los productores, la tenencia de la tierra es propia. El Catimor (hibrido de timor x caturra) es la variedad más utilizada. Las principales plagas que inciden son nematodos fitoparásitos (Pratylenchus y Meloidogyne), gallina ciega (Phyllophaga spp.) y broca del café (Hypothenemus hampei), las enfermedades causadas por hongos, ojo de gallo (Mycena citricolor), roya (Hemileia vastatrix) y moho de hilachas (Pellicularia koleroga), las arvenses más reportadas por los productores, Ventanilla (Monstera adansoni) y Zacate estrella (Cynodon dactylon). El método de control más usado para, plagas insectiles, nematodos, enfermedades fungosas y arvenses, son los sintéticos. Gran parte de los productores no realizan análisis del café antes y después del beneficiado húmedo, ni limpieza de su medio de transporte al trasladar el café a centros de acopio.
