Abstract:

Empoasca decipiens (Paoli) and Asymmetrasca decedens (Paoli) (Homoptera: Cicadellidae) are among the most significant pests on cotton in Amik Plain. In 2008 and 2009, the studies were carried out in 50 cotton fields located in Kırıkhan, Reyhanlı, Kumlu, Demirköprü and Uydukent districts of Hatay province. From each district 10 different cotton fields and from each cotton field 25 sweep-net samplings were taken for each sampling.During the sampling period of 2008, a total of 3.113 adults of E. decipiens and A. decedens were collected from all the cotton fields sampled. The localities in which the highest numbers of those species sampled were in the following order: Demirköprü, Uydukent, Reyhanlı, Kırıkhan and Kumlu. Population of density differed depending on the sampling month. For example, in Reyhanlı, Demirköprü, Uydukent and Kırıkhan, caught numbers were higher in July than these of August. In Kumlu, however, numbers observed to be parallel for July and August.During the sampling period of 2009, a total of 9.119 adults of E. decipiens and A. decedens were collected from all the cotton fields sampled. The localities in which the highest numbers of those species sampled were in the following order: Kırıkhan, Demirköprü, Reyhanlı, Kumlu and Uydukent. Population of density differed depending on the sampling month. For example, in Kumlu, Demirköprü and Kırıkhan, caught numbers were lower in July and August than in September and October, whereas in Reyhanlı and Uydukent, numbers were lower in July and September and higher in August and October. In general, population density of leafhoppers in Kırıkhan, Demirköprü and Uydukent were significantly higher than those of Reyhanlı and Kumlu.
