Potato, Solanum tuberosum L., is one of the most important food crops. The potato tuber moth (PTM), Phthorimaea operculella (Zeller 1873) (Lepidoptera: Gelechiidae), is a destructive pest of potato in the field, storage and during marketing. The site of the current investigation is Etay El-Baroud, Agricultural Research Station (Beheira Governorate) in 2022 summer season, to test the efficiency of sex- pheromone traps in capturing the male moths of P. operculella. The impacts of sex- pheromone trap color, trap direction, and trap height on P. operculella potato moth captures were evaluated. Every trap had a pheromone capsule as bait. White pheromone traps were the most effective at capturing insects with an average number of male moths (3312.23 ± 169.78 / trap / month), than yellow ones (2216.70 ± 152.63), green traps (1301.00 ± 103.48 male moths / trap per month) or red traps. Depending on the direction of the sex- pheromone trap, there were significant variations in the number of catches. When the traps were positioned in the south (3179.25 ± 150.58 male moths / trap) or center (3109.43 ± 126.15 male moths / trap) of the PTM-infested area, more moths were caught than when they were positioned in the west, east, or north. The ground-resting traps captured more P. operculella moths collectively with an average of (3888.50 ± 169.28 individuals / month / trap)
