Abstract:
Heixiazi Island locates in the easternmost end along the Sino-Russian border of Fuyuan County,Heilongjiang Province.Adult horseflies take blood meals from various mammals including humans and are known to cause multiple zoonoses.There was still no information nowadays about the distributions and seasonal activities of horseflies in Heixiazi Island,and no sufficient controlling measures to reduce their harms to livestock and humans.The species diversity and seasonal activities of horseflies on Heixiazi Island were investigated during June to August of 2012 and 2013 with traps (Horsefly Trap,Alcoche-Hygiene,Holand) every 500 m apart along the wet meadows of forest edge,river banks and villages.A total of 5 941 specimens including 9 species of five genera were identified.Tabanus griseinus was the dominant species accounted for 40.57％,and followed by Atylotus miser accounted for 35.15％.The species diversity index was higher in late July,and then declined gradually over the successive two months.Hybomitra distinguenda prefer to breed in the wet meadows alone the forest edge,while A.miser and T.griseinus are the dominant species near the human settlements.The population structure of horsefly's community appeared to be relatively stable in late June in respect to species diversity obtained by trap sampling.The species dominance index was relatively higher with several dominant species in early August.The results indicated that the high-risk period for horsefly-borne diseases in Heixiazi Island area is from mid-June to all July of a year.
