我国东北吉林省和黑龙江省的边境地带共有18个县区,东起于吉林省珲春县,北止于我国最北端的黑龙江省漠河县,全长约2500km,位于东经122°4′—129°50′,北纬53°—41°25′之间,一般海拔500—1000m,年平均降水量300—700mm,昆虫地理区划属东北区大兴安岭亚区和长白山亚区。多年来。
Faunal and ecological studies of wood-sucking midg s carried out during 1980-1988 in 10 border of Northeast China, 4 new species and 5 new records of species are identified. Ecological investigations show that Culicoides obsoletus (35.7%) and C, punctatus (34.9%) are predominant species. The composition of midges varies with different habitats, places and seasons. The active durations are 110 days for C. punctatus, and 100 days for C.sinanoensis and C. erairai. During active seasons, there is only one peak for C.pulicaris, C.pallidicornis, and C. erairai, and two peaks for C. obsoletus, C. sinanoensis and C. punctatus. Diurnal observations on 5 species show that within 24 hours, two peaks of C, pulicaris, C.obsoletus, C.sinanoensis and C. punctatus appear at 1-2 hours after sunrise and sunset, C. odibilis, the peak appears at 2 hours before sunrise, and its active duration is from midnight to day break.
