The Cixiidae and Cicadellidae (Hemiptera) Species Harmful on Vegetables from Solanaceae in Konya Province’ Turkey

This study was carried out in 2006-2007 to determine Cicadellidae and Cixiidae species, important vectors from Homoptera, and their population developments on tomato, pepper, eggplant and potato plants from Solanaceae in Meram district where the vegetable production is highest in Konya Province. Although the sam-ples collected in both years, the regular observations for population development were conducted in 2007. As a result; 1738 samples from Cicadellidae and 30 samples from Cixiidae were collected. As a result 15 species from 13 genera from Cicadellidae family were determined. Hyalesthes obsoletus Signoret from Cixiidae family was also identificated. Six species from Cicadellidae are new record for Konya. According to the 2007 results the most common species were Zyginidia sohrab Zachvatkin (53%), Empoasca decipiens Paoli (41%) and Psammotettix striatus (Linnaeus) (3%), respectively. These species were oc-curred on Solanaceae vegetable plants during June, July and August. Z. sohrab was peaked in mid-June. Whereas a drop population observed in July and August then it suddenly increased at the beginning of September. The most numerous insects was observed on potato (50,6%), pepper (16,8%), eggplant (16,7%) and tomato (15,7%) from the tested Solanaceae plants, respectively. While, Z. sohrab was dominat species on other three plants, E. decipiens was on potato with the rate of 50.4% and then followed by Z. sohrab at level of 43.4%. Sola-num nigrum, Datura stramonium and Athropa belladona were determined as common weed species from Solanaceae in the district. E. decipiens (62%), Hy-alesthes obsoletus (10%) and Z. sohrab (9.5%) were collected from them, too. Chrysopa carnea Sch (Chrysopidae:Neuroptera), Coccinella septempunctata (L.), Coccinula quatuordecimpustulata (L.), Scymnus bivulnerus Capra and Adalia sp. (Coccinellidae:Coleoptera) were dominant predators of leafhoppers. No parasitoid was found.
