RESUMEN Los cultivos comerciales de flores en Colombia se realizan principalmente en invernaderos de cubierta plástica en la Sabana de Bogotá. Este estudio examinó la abundancia y la actividad de vuelo de los thrips en un cultivo de crisantemo, a partir de los individuos capturados directamente en las plantas y los obtenidos de trampas amarillas con pegante, tanto comerciales como no comerciales (artesanales), instaladas en el cultivo. Frankliniella occidentalis fue la especie dominante y presentó asociación con los diferentes estadios fenológicos de las plantas muestreadas. La abundancia de larvas y adultos no se distribuyó uniformemente en el invernadero. El método absoluto de muestreo de plantas encontró 2.5 veces más larvas de thrips que el método relativo por golpeo en plantas. Para las trampas no comerciales, no hubo diferencia en el número de thrips a diferentes alturas de las trampas; sin embargo, las trampas orientadas hacia el suroeste capturaron significativamente más thrips que las trampas orientadas al noroeste, noreste y sureste. Se encontró una moderada correlación positiva entre el número de thrips muestreados en las plantas y la ubicación espacial de las trampas comerciales. Los resultados que aquí se presentan proporcionan una base para diseñar y estandarizar métodos de muestreo directo para thrips en plantas y muestreo indirecto utilizando trampas amarillas con pegante para el monitoreo y manejo de thrips en cultivos ornamentales bajo cubiertas plásticas en Colombia.

ABSTRACT Commercial flower crops in Colombia are largely grown within plastic greenhouses in the Sabana de Bogotá (Bogota Plateau). This study examined the abundance and flight activity of thrips in a chrysanthemum crop, estimated from plant samples, commercial yellow sticky traps, and non-commercial (self-crafted) yellow sticky tape traps installed in the crop. Frankliniella occidentalis was the dominant species present associated with all plant phenological stages. Abundance of larvae and adults was not evenly distributed throughout the greenhouse. An absolute method of plant sampling found 2.5 times more thrips larvae than the relative method of sampling plants by beating. For non-commercial traps, there was no difference in the number of thrips at different trap heights; however, traps facing the south-west caught significantly more thrips than traps facing north-west, north-east, and south-east. A moderate positive correlation was found between the number of thrips sampled on plants and the spatial location of the commercial sticky traps. The results found here provide a basis to design and standardize direct sampling methods for thrips on plants and indirect sampling using yellow sticky traps for monitoring and managing thrips in ornamental crops under plastic covers in Colombia.

Abstract The effect of hydrogel (0, 3, 6, and 9 g per seedling) on the survival and growth of Cariniana pyriformis seedlings under different water regimes (absence of irrigation, 60% and 100% field capacity) in a sandy loam soil was assessed. The experiment was carried out in an agricultural nursery with drip irrigation, implementing a completely randomized block design in a split-plot scheme. After 20 weeks of evaluation in both treatments with irrigation, the maximum dose showed a slight increase (9%) in stem diameter and seedling height compared with the control treatment, although the aerial and root dry biomass did not show differences. For the treatment without irrigation, the survival had a linear response with increasing doses, from 24% (0 g per seedling) to 65% (9 g per seedling). C. pyriformis responds positively to hydrogel when a severe water deficit occurs.

Neste artigo, apresentamos como tema de estudo a Educação Corporal. Trata-se de ler Friedrich Nietzsche à luz das ideias de gosto, corpo e educação, com o interesse de abrir os horizontes de interpretação para um cenário acadêmico necessitado de (outra) significação. Recorremos ao pensamento de Nietzsche para abordar assuntos que ele, propriamente, nunca chegou a explorar, como a formação do gosto a partir do corpo numa perspectiva pedagógica em direção a uma Educação Corporal. Em nossa pesquisa, os conceitos de formação do gosto e de corpo nos servem como ferramentas analíticas.

In this article we are presenting a topic of study referred as body education. We have read Friedrich Nietzsche in the light of the ideas of taste, body and education, with the interest of expanding the horizons of interpretation for an academic setting in need of a (another) meaning. We have appealed to Nietzsche's thought in order to approach study objects he never explored properly, such as the formation of taste from the body in a pedagogical perspective and towards a body education. We have discovered that the concepts of taste formation and body may serve as analytical tools for our research.

En este artículo estamos presentando un tema de estudio: la Educación Corporal. Tratamos de leer a Federico Nietzsche a la luz de las ideas de gusto, cuerpo y educación con el interés de abrir horizontes de interpretación para un escenario académico necesitado de una (otra) significación. Recurrimos al pensamiento de Nietzsche con el fin de abordar objetos que él propiamente no llegó a explorar nunca como son la formación del gusto desde el cuerpo en perspectiva pedagógica y hacia una Educación Corporal. Encontramos que los conceptos de formación del gusto y de cuerpo nos sirven como herramientas analíticas para nuestra investigación.
