Abstract :
This study was carried out to evaluate efficiency sticky traps on attraction Greenhouse Whitefly, Trialeurodes vaporariorum (Westwood) (Homoptera: Aleyrodidae) infested Carnation flowers (Dianthus caryophyllus L.) under glasshouse conditions at two locations (governorates) El-Orman Garden (Giza governorate) and International Garden (Alexandria Governorate) during 2020 season. This study is divided into three parts, first part studied the evaluation efficiency color of the sticky trap on attraction T. vaporariorum through a comparison between five colors (yellow, blue, red, green and white). Results showed that the traps which have yellow color more efficiency than others which have (blue, red, green and white) color, respectively. The second experiment aimed to evaluate the efficiency height of the yellow sticky traps on attraction T. vaporariorum thorough comparison between four heights (2m, 1.5m, 1m and 0.5m) above the ground. Results showed that the trap which has 2m height above the ground more efficiency than others which have (1.5m, 1m and 0.5m) heights, respectively. The third experiment aimed to evaluate the efficiency orientation of the yellow sticky traps on attraction T. vaporariorum thorough comparison between four orientations (North, South, East and West). Results showed that had no clear effect of the trap orientation on attraction T. vaporariorum at both two locations.
