ABSTRACT Eresus cinnabarinm (Olivier, 1789)'DA (ORDO: ARANEAE) FENOLOJİ KESMEZO?LU, Selda M.S.c. in Biology Supervisor: Asst. Prof. Dr. Muhammed Ismail VAROL Eylül 2004, 66 sayfa In this work, bringing out eggs, hatching out eggs, maturing periods of Eresus cinnabarinm were worked. Eresus cinnabarinus is a model of Palearctic and it' s poison gland is big and dangerous for people when compared with other spiders. This species has a large distribution area that is registrated from Europe, Caucasicus and Mezopotamya. In our country, Eresus cinnabarinus shows distribution in Southeast Anatolia, East Anatolia, the Mediterranean and Central Anatolia. Eresus cinnabarinus is observed in a special cage (vivarium) in the room of raising animals. It is observed that the female Eresus cinnabarinus brought out a coccon at 21.06.2003, the coccon hatched at 18.08.2003 and the spiderlings hatched out the coccon. It was observed that the bringing out the eggs period of E. cinnabarinus was half of the June. It was determined that the spiderlings hatched out of coccon in the second half of the August so the embriyology of E. cinnabarinus lasted two months, and they matured in February -April of the later year. It was established that the female Eresus prepared the nutriment for spiderlings by imprisoning itself in coccon at the end of its life span. Three hundred and eighty two spiderlings hatched out of coccon and the spiderlings were fed by Drosophila sp. which was grown in vitro. Key words: Spiders, Eresidae, Pheonology u
