Modelización espacial de huevos de Thrips (Thysanoptera: Frankliniella occidentalis) en tomate de cáscara por medio de técnicas geoestadísticas
The husk tomato (Physalis ixocarpa Brot.) is a staple food crop of great economic importance in Mexico. However, it is affected by various pests and diseases, such as Thrips (Thysanoptera: Frankliniella occidentalis) and the tomato spotted wilt virus (TSWV) that can cause up to 80% of losses. The sc...

The scope of the present work was to model the spatial distribution of eggs of Thrips using geostatistical techniques as well as to obtain maps of incidence via krigging. In each of the commercial fields associated to the localities of Luvianos, Jocotitlan e Ixtlahuaca, 121 sampling points were georeferenced through the method of transects across three phenological stages of the crop.

El tomate de cáscara (Physalis ixocarpa Brot.) es un cultivo alimenticio de gran importancia económica en México. Sin embargo, es afectado por diversas plagas y enfermedades tales como los Thrips (Thysanoptera: Frankliniella occidentalis) y el virus de la marchitez manchada del tomate (TSWV) que llegan a causar hasta un 80% de pérdidas. El objetivo del presente trabajo fue modelizar la distribución espacial de huevos de Thrips mediante técnicas geoestadísticas y obtener, en consecuencia, mapas de incidencia por medio del Kriging. Se georreferenciaron 121 puntos de muestreo en cada una de las parcelas comerciales de los municipios de Luvianos, Jocotitlán e Ixtlahuaca, a través del método de transectos en tres etapas fenológicas del cultivo. Se contabilizó el número de huevos de Thrips en cada punto de muestreo. Los resultados mostraron que las poblaciones de huevos deThrips presentan una distribución agregada, identificándose varios centros de conglomeración a través de los mapas obtenidos. Los semivariogramas obtenidos de la distribución espacial se ajustaron principalmente a los modelos gaussianos y esféricos. La distribución de huevos de Thrips se presentó en centros de agregación dentro de las parcelas estudiadas, lo cual permitirá establecer estrategias y medidas de control o mitigación en términos de sitios específicos de infestación de huevos de Thrips.
