The Cotton whitefly, Bemisia tabaci is an important pest of cotton which by transmitting plant pathogenic viruses cause damage and reduce lint quality. The attractiveness and oviposition preference of B. tabaci for seven cotton cultivars (Okra, Red Okra, khordad, Sahel, Mehr, Varamin and Termus 14) of two species of cotton (Gossypium hirsutum L.)and(Gossypium barbadence L. were studied in a choice test in greenhouse and laboratory conditions 24±2 ºC, 65±5% relative humidity and photoperiod 16:8h (L: D). Results showed that, the number of whitefly at different time intervals (48 to 72 h) in the greenhouse and laboratory conditions on Termus 14 cultivar was significantly higher than other cultivars (P< 0.01). In the choice test the highest mean number of egg deposited on the leaves 72 h after the infestation was observed on Termus 14 and it was significantly higher than other cultivars (P< 0.01). According to these results, B. tabaci was highly attracted by the whitefly and oviposition preference on Termus 14 representing the susceptibility of this cultivar to activity of B. tabaci rather than the others. The results obtained here can be used in integrated management programs of this whitefly in cotton field.
