Abstract EN
This study was conducted to evaluate the negative effects of whiteflies on productive and qualitative measurements of “Aleppo 118” variety of cotton.
The experiment was conducted in Tal-Aran village, Aleppo Governorate, muslin covered cages, and each cage was considered a replicate containing 10 cotton plants.
The release of whitefly adults was conducted on August 1 every season at four different densities (0 adults, 200 adults, 400 adults and 800 adults, in addition to uncovered plot as a control).
The results obtained showed that there was no effect of cages on the evaluated components.
A negative correlation was found between different whiteflies densities and cotton yield.
The yield of the treatment where no adult whiteflies were added exceeded all other treatments where an artificial whitefly adult was released at different levels.
Loss in cotton balls increased from 63.05 to 72.97%, and the loss in cotton yield increased from 71.94 to 76.89%.
The loss in boll weight increased from 5.86 to 24.4% when the density of nymphs increased from 90.67 to 822.07 nymph/leaf during 2018 season.
In 2019 season, yield loss was less than in the previous season and loss in cotton yield increased from 7.69 to 34.80%.
Loss in boll weight increased from 5.75 to 14.21% when the density of whitefly nymphs increased from 76.47 to 701.2 nymph/leaf.
Likewise, the correlation between whiteflies nymph density and yield components was R= -0.681 and R= -0.706 during 2018 and 2019 growing seasons, respectively, which confirm the negative effect of whiteflies on cotton yield and lint quality.
