بررسی تاثیر رنگ تله فرومونی در میزان جلب و شکار پروانه چوبخوار پسته، Kermania pistaciella

Kermania pistaciella Amsel is an important pistachio pest in Iran which exists in most of the country’s pistachio-growing areas. Mostly, Pistachio twig borer moth causes damage to the wood. This pest’s larvae penetrate the wood immediately after hatching and start damaging. In order to combat pistachio twig borer moth, the picnics are determined using pheromones trap that attract this pest’s male insects, and then, the time of chemical control of this pest was determinated. This study was conducted to determine flight peak and color effect on attracting this pest. Three hectares from pistachio gardens were selected with similar conditions and appropriate pollution of this pest; each hectare was considered as one block, and three pheromone traps were installed in each block. Pheromone traps had three colors: white, red and blue. The pheromones that used in all traps were equal. Daily traps counting was performed from the time of installation (03.01.1399) up to the time of non –absorption of butterfly (07.02.1399), and the data were analyzed by SPSS software. On the basis of the obtained data from pheromone traps, the flight peak of Kermania pistaciella was determined on 28.01.1399. The highest absorption belonged to the red trap with 400 butterflies, and the average rate of this red trap was 95.08 during the project execution. The lowest absorption was observed in the blue trap: the highest hunt of this color was 63 butterflies and average hunting of this trap was 13.15 during the project time. Accordingly, the most hunting took place in red, white and blue traps, respectively.
