Abstract

Flower thrips tend to form areas of high population, termed “hot spots,” in blueberry plantings. This study provided evidence that thrips density may be correlated with flower density in space. Further understanding of the relationship between flower density and thrips numbers could lead to better scouting and management programs.

 

Sumario

 

Los trips de las flores suelen formar zonas de alta población, que se llaman “puntos calientes”, en las plantaciones de arándanos. Este estudio provee evidencia de que la densidad de trips se puede correlacionar con la densidad de las flores en espacio. Una mayor comprensión de la relación entre la densidad de las flores y el número de trips podría resultar en mejores programas de muestreo y de manejo.
