[Blood-sucking biting midges (Ceratopogonidae) in north central Siberia].

6000 adult punkies were collected from man and animals over a period of 15 years in the Taimyr and Evenki Autonomous Okrugs of Krasnoyarsk Territory. Four species Culicoides chiopterus, C. pulicaris, C. fascipennis, C. alatavicus are reported from tundra and forest-tundra of Taimyr (68 degrees 00'-73 degrees 13' N). Punkies of the above species are small in number and do not occur all over the region. In northern and middle taiga of Evenkia (60 degrees 20'-65 degrees 45' N) punkies are very abundant and occur everywhere. 7 species C. obsoletus, C. chiopterus, C. punctatus, C. pulicaris, C. grisescens, C. fascipennis, C. helveticus are reported from this region. A relative abundance of punkies in the complex of bloodsucking Diptera during a summer period in different landscape zones is shown. Their seasonal and daily activity is shown and maximum levels of attacking man, reindeer and dog are given.
