Grape is one of the major horticultural industries and ranks second in the area devoted to cultivation of fruit trees in Iran. There are many grape cultivars in the west of Iran. Grape vine moth is a major pest of grapes in Iran and it causes huge losses in quantity and quality of grape products every year. There is not any information regarding concentrations, delta traps colors and heights and attractiveness of cultivars on Lobesia botrana in Iran. This experiment was thus conducted to address this lack in information and based on the aforementioned parameters. Because of the importance of this pest, the concentration effects of pheromone, delta trap colors (white, yellow, green, brown and multi-color) and their heights (0.5, 1 and 1.5 m) on trapping of moth for optimal monitoring, research was performed in the west of Iran (Kurdistan). The effects of trap color (P = 0.114) and Trap height (P = 0.919) to attract pests were not significant. The results showed that ground slop did not have a significant effect on attraction of adult grape vine moths.
