Resumen

Se realizaron experimentos para determinar la preferencia de color de trips ( Frankliniella occidentalis check for this species in other resources Pergande) en cultivos de pimiento ( Capsicum annuum check for this species in other resources L.), en las localidades de Cerrillos de Tamaya (30° lat. S.; 71°16' long. O) y Pan de Azúcar (29°55' lat. S; 71°14' long, O) de la IV Región de Chile. En diseño de bloques completos al azar, se compararon trampas de pegamento azul, blanco, blanco-azul y amarillo.Los resultados mostraron que F. occidentalis fue la especie predominante en el cultivo de pimiento. En la trampa de color azul, blanco-azul y blanco se capturaron significativamente más trips que en las trampas amarillas, cuando las capturas fueron superiores a 300 trips semanales por trampa. Los resultados fueron erráticos con capturas inferiores.

Abstract

Experiments were conducted in order to determine color preference of thrips ( Frankliniella occidentalis check for this species in other resources Pergande) in sweet pepper ( Capsicum annuum check for this species in other resources L.)crops in the localities of Cerrillos de Tamaya (30° S lat; 71°16' W long) and Pan de Azúcar (29°55' S lat; 71°14' W long), IV Region, Chile. Blue, white, white-blue, and yellow sticky traps were compared in a randomized complete block design experiment. Results showed that F. occidentalis was the predominant species in the pepper crop. In the blue, white-blue and white traps significantly more thrips were caught than in the yellow traps, when the number of captures was more than 300 thrips per week per trap. The results were erratic with lower numbers of captures.
