Abstract

The damage of sugarcane whitefly,Neomaskellia andropogonic Corbett, has recently increased dramatically in sugarcane fields in Khuzestan province. In this study, biology of N. andropgonis on four sugarcane commercial cultivars was evaluated under laboratory conditions. In this experiment, the preimaginal development, adult longevity and fecundity were studied in a growth chamber that was set at 27± 1oC, 60-70%R.H. and 12:12 light dark. The leaf cages were used for the experiment and the cultivars included CP69-1062, CP57-1062, CP48-103 and NCO-310. Mean preimaginal development time was 24.09, 28.06, 27.27 and 26.64 days on the above mentioned cultivars, respectively, producing only female whiteflies. Mean longevity of females was 6, 8.49, 4.15 and 4.60 days on four cultivars, respectively. Females laid 61.80, 58.80, 41.10 and 39.38 eggs on CP69-1062, CP57-1062, CP48-103 and NCO-310 cultivars, respectively. According to the results of this study, the biotic parameters of the pest were lower in CP48-103 and NCO-310 than the other two cultivars.
