Abstract:

Aims: The aim of this study is to determine the pest species belonging to the Cicadellidae family and their egg parasitoids on two Citrus spp. (cv. Washington Navel and cv. Okitsu) in Adana province of Türkiye. Methods and Results: In order to collect the leafhopper and parasitoid species, samplings were carried out in 5 different orchards. Leafhopper species were collected by using a D-Vac insect aspirator and yellow sticky traps. Egg parasitoids were determined by culturing leafhopper-infested leaves in lab conditions. As a result of this study, 7 species belonging to the 3 subfamilies of Cicadellidae (Hemiptera) were identified. These species are; Austrogallia sinuata (Mulsant Rey, 1855), Asymmetrasca decedens (Paoli, 1932), Empoasca decipiens (Paoli, 1930), Zyginidia sohrab (Zachvatkin, 1947), Cicadulina bipunctella (Matsumura, 1908), Psammotettix striatus (Linnaeus, 1758), Balclutha hebe (Kirkady, 1906). Among the collected species, Cicadulina bipunctella, Asymmetrasca decedens & Empoasca decipiens, Zyginidia sohrab were detected as the most common and abundant Cicadellid species. Conclusions: In the sampled area, Cicadulina bipunctella, Empoasca decipiens & Asymmetrasca decedens, Zyginidia sohrab were determined as most abundant species. In addition, Anagrus atomus (Hymenoptera, Mymaridae) was determined as the egg parasite of the leafhopper species. Significance and Impact of the Study: Since leafhopper species are potential virus vectors therefore population fluctuations should be monitored closely.
