Última Incidencia del gusano cogollero Spodoptera frugiperda Smit en Ocoyucan, Puebla y actividad bioinsecticida de semillas de Carica papaya L. y Trichilia havanensis Jacq. Colegio de Postgraduados Figueroa Brito, Rodolfo. El maíz es el principal cultivo de México y constituye la base de la alimentación de la población. Entre los factores que limitan la producción en este cultivo están los insectos plaga, destacando los daños ocasionados por el gusano cogollero Spodoptera frugiperda. Se evaluaron en laboratorio los productos naturales de las semillas de Carica papaya y Trichilia havanensis sobre S. frugiperda y su enemigo natural Chrysoperla carnea. En invernadero, se evaluó el sulfato de amonio (13.6 g), urea (6 g), fosfonitrato (6.56 g) y la vermicomposta con tierra negra (1:3) en bolsas de plástico (6 kg) junto con el extracto acuoso de semillas de C. papaya al 20 % en plantas de maíz. En campo, se entrevistaron 35 productores de maíz del municipio de Ocoyucan, Puebla,...

Ano: 2011 URL: http://hdl.handle.net/10521/494 Applying Retrospective Demographic Models to Assess Sustainable Use: the Maya Management of Xa’an Palms Ecology and Society Xa’an palm (Sabal yapa) has been used to thatch traditional Maya houses for over 3000 years. In the Yucatan Peninsula, this palm has been introduced to pasturelands, maize fields (milpas), and homegardens. These and other traditional management systems are usually believed to be sustainable, but there is as yet little evidence to support this hypothesis. Demographic models have been used for this purpose, mainly focusing on population growth rate (λ). So far, retrospective analysis has not been applied, even though it examines how changes in the the life cycle of a species, caused by different management regimes, affect its λ. In this study, we assess whether ecologically sustainable use of xa’an occurs in...

Ano: 2005 Periodic Closures as Adaptive Coral Reef Management in the Indo-Pacific Ecology and Society Cinner, Josh; James Cook University; joshua.cinner@jcu.edu.au; Marnane, Michael J; Wildlife Conservation Society;; McClanahan, Timothy R; Wildlife Conservation Society; tmcclanahan@wcs.org; Almany, Glenn R.; James Cook University;. This study explores the social, economic, and ecological context within which communities in Papua New Guinea and Indonesia use adaptive coral reef management. We tested whether periodic closures had positive effects on reef resources, and found that both the biomass and the average size of fishes commonly caught in Indo-Pacific subsistence fisheries were greater inside areas subject to periodic closures compared to sites with year-round open access. Surprisingly, both long-lived and short-lived species benefited from periodic closures. Our study sites were remote communities that shared many socioeconomic characteristics; these may be crucial to the effectiveness of adaptive management of reef resources through periodic closures. Some of these factors... Tipo: Peer-Reviewed Reports Palavras-chave: Adaptive management; Coral reefs; Socioeconomic; Periodic closures; Traditional management; Social-ecological systems. Ano: 2006 Spatial variability of soil chemical properties after coffee tree removal Rev. Bras. Ciênc. Solo Vieira,Sidney Rosa; Guedes Filho,Osvaldo; Chiba,Márcio Koiti; Cantarella,Heitor. Assessing the spatial variability of soil chemical properties has become an important aspect of soil management strategies with a view to higher crop yields with minimal environmental degradation. This study was carried out at the Centro Experimental of the Instituto Agronomico, in Campinas, São Paulo, Brazil. The aim was to characterize the spatial variability of chemical properties of a Rhodic Hapludox on a recently bulldozer-cleaned area after over 30 years of coffee cultivation. Soil samples were collected in a 20 x 20 m grid with 36 sampling points across a 1 ha area in the layers 0.0-0.2 and 0.2-0.4 m to measure the following chemical properties: pH, organic matter, K+, P, Ca2+, Mg2+, potential acidity, NH4-N, and NO3-N. Descriptive statistics were... Tipo: Info:eu-repo/semantics/article Palavras-chave: Geostatistics; Soil fertility; Traditional management; Semivariogram.
