Evaluation Efficiency Sticky Traps on Attraction Bemisia tabaci (Genn.) on Cucumber Plants under Greenhouses Conditions

Abstract

This study was carried out to evaluate efficiency sticky traps on attraction Bemisia tabaci (Genn.) on Cucumber plants var. Cucumis sativus L. under greenhouses conditions in two locations, Perkash (Giza governorate) and Tokh (Qalubiya governorate) during 2018 season. This study contains three experiments, first experiment aimed to evaluation efficiency of the sticky trap color on attraction B. tabaci through comparison between four colors (yellow, blue, orange and red). And this experiment was carried out on Cucumber (early summer planting) during (February - March). Results showed that the traps which have yellow color more efficiency than others which have (blue color, orange color, and red color), respectively. Second experiment aimed to evaluation efficiency yellow sticky trap height on attraction B. tabaci through comparison between four heights (2m, 1.5m, 1m and 0.5m) above the ground. And this experiment was carried out on Cucumber (summer planting) during (April - May). Results showed that the trap which have 2m height above the ground more efficiency than others which have (1.5m, 1m and 0.5m) heights, respectively. Third experiment aimed to evaluation efficiency orientation of the yellow sticky trap on attraction B. tabaci through comparison between four orientations (North, South, East and West). The experiment was carried out on Cucumber (late summer planting) during (June - July). Results showed that had no clearly effect of the trap orientation on attraction B. tabaci .
