Prey Selection By African Catfish Clarias Gariepinus (Burchell, 1822) Larvae Fed Different Feeding Regimes, Erdal Yilmaz, Ahmet Bozkurt, Kaya Gökçek
Turkish Journal of Zoology
Live prey selection by African catfish, Clarias gariepinus, larvae was examined under laboratory conditions. Larvae were offered plankton, plankton + trout starter (TS) and plankton + betaine supplemented trout diet (BTS) for 7 days after exogenous feeding. Five larvae were sampled to determine their gut contents and selectivity index for each treatment 15 min after the feeding. It was observed that dry diets (TS and BTS) improved the growth (P < 0.05), but did not significantly influence the prey selection of the larvae. It was determined that African catfish larvae preferred Copepods and Rotaria sp. to other zooplankton species for all feeding regimes.

A survey of parasitoids of the citrus leafminer, Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae), was carried out in the citrus orchards in the east Mediterranean region of Turkey during 1995-2001. Their relative abundance and rate of parasitism were also determined. Ten species of parasitoids were identified: Cirrospilus sp. nr. lyncus (Walker), C. pictus (Nees), C. variegatus (Masi), C. vittatus Walker, C. ingenuus Gahan, Ratzeburgiola incompleta (Boucek), Diglyphus isaea (Walker), Semielacher petiolatus (Girault), Citrostichus phyllocnistoides (Narayanan), Neochrysocharis formosa (Westwood) (Hymenoptera: Eulophidae). Neochrysocharis sp., Chrysocharis sp., Barycapus sp., Pnigalio sp. (Hymenoptera: Eulophidae) and the Pteromalus sp. (Hym.: Pteromalidae) were also identified. Among these …

Turkish Journal of Zoology
This study was carried out in order to determine parasitoid species of the family Agromyzidae (Diptera) in Diyarbakır and Mardin provinces during 2002-2004. Infested leaves with leafminer larvae were collected from both cultivated and non-cultivated plants twice a month. The adult parasitoids were obtained by rearing from infested leaves in the laboratory. Five parasitoid species belonging to the Braconidae (Hymenoptera) were found. These species, Bracon kirgisorum Telenga, 1936, Opius basalis Fischer, 1958, O. monilicornis Fischer, 1962, O. quasipulvis Fischer, 1989, O. exiguus Wesmael, 1835. B. kirgisorum, O. basalis and O. quasipulvis, were new records for the Turkish fauna. In this …
