Aim: The aim of this study was to determine the seasonal distribution oflarvae and pupae of Culicoides species.

Materials and Methods: Mud samples (9420 cm3) were collected at regular intervals from three regions of Konya province at January - December 2004. Larvae and pupae were obtained with saturated sugar flotation technique. The larvae and pupae of Culicoides species were transferred into 30 cm length and 1 cm diameter tubes. To become adult, 5 mm width white filter paper was placed into the tubes, 1 cm space at the top of the tubes, and closed with cotton. Culicoides samples were collected gently using a special rechargeable small vacuum cleaner and after were preserved in 70% ethyl alcohol.

Results: Adults 193 and 146 Culicoides were obtained from 258 larvae and 192 pupae, respectively. The highest number oflarvae and pupae was determined in August (59 larvae and 35 pupae) and July (41 larvae and 32 pupae). Four larvae and nine pupae, 22 larvae and 16 pupae, 24 larvae and 29 pupae, 29 larvae and 17 pupae and 14 larvae and 8 pupae were determined in April, May, June, September and October, respectively.

Conclusions: The highest number of larvae and pupae of Culicoides was determined in August and July, and the lowest number oflarvae and pupae were collected in April. Larvae and pupae were not seen during winter.
