Abstract	Population development of the leafhoppers (Asymmetrasca decedens Paoli and Empoasca decipiens Paoli) (Homoptera: Cicadellidae) on various cotton varieties in Çukurova region of Turkey was investigated during the years 2002 and 2003. Leafhoppers showed a peak population development at boll formation stage of the cotton varieties in July and then, their numbers declined to low levels throughout the season in both years. The population developments of leafhoppers were apparently different between hirsute and glabrous cotton varieties. The mean numbers of leafhoppers on glabrous (Çukurova 1518, Nektarsız ÇUF 2 and SG 125) and less-hirsute varieties (Caroline Queen and Nazilli 84) were significantly higher than that of hirsute (Erşan 92, Maraş 92 and Stonevilla 453) or semi-hirsute (Sayar 314) varieties. The mean numbers of leafhoppers on some glabrous varieties exceeded the threshold level (10 leafhopper per leaf) for 2 weeks in 2002 and 4 to 5 weeks in 2003. The mean numbers of leafhoppers on Adana 98 cotton variety, which is less pubescent and have okra-leaves, were significantly lower than that of glabrous and normal-leafed varieties, and in general, this variety fell into the same group with resistant varieties in both years.
