Análisis espacial de las poblaciones de Frankliniella occidentalis (Pergande) en un cultivo de fresa bajo cubierta, como soporte en las decisiones de manejo integrado de plagas
Spatial dependence of Frankliniella occidentalis (Pergande) in a covered strawberry crop was established at Bogota plateau. Thrips populations were monitored for 12 weeks in an area of eight by 13 quadrants (each quadrant of 8 x 4 m), taking three flowers per quadrant. Data analysis was done with Surfer and GS+/386 programs. Geostatistics, based on semivariogram and correlogram analyses were used. There were analyzed O, 45, 90, and 135 degreed of directionality. Spatial dependence were found in three ofthe twelve weeks and they indicated that spatial dependence of thrips populations showed boundaries from one to six quadrants and were more frequent in Oand 45 degrees of directionality. No dependence was observed at 90 degrees. InitialIy, the thrips colonies were aggregated but, in time, changed this aggregated pattern toward a random pattern due to thrips movement to neighboring quadrants. Finally, we discuss the importance of spatial dependence as a tool for thrips management.
