Abstract
Abstract The effect of bucket trap color on grape root borer (GRB), Vitacea polistiformis Harris, captures was evaluated in 2005 and 2006. Traps were deployed in a commercial vineyard consisting of muscadine (Vitis rotundifolia Michx) grapes in North-Central Florida. Experimental designs were randomized complete block with four tratments including green, yellow, white and blue traps in 2005. In 2006, five treatments (green, yellow, green top, yellow top, and multicolor) and four replicates were evaluated. All traps were baited with GRB female sex pheromone. Trap color had a significant effect on the number of GRB males captured. In 2005, green and yellow traps caught more GRB males than other trap colors. In addition, first GRB male captures were in yellow and green traps. In 2006, the multicolor trap caught more GRB males than any other trap and had the first GRB capture. Grape root borer males prefer green and yellow pheromone-baited traps, but do not appear to distinguish between these two colors, whic...
