Abstract
Flies were collected using putrefied baits once a week, a total of 31, times in Mt Jiryong, Korea from June 1, 1988 to May 31, 1989. The number of flies collected was 13,365, with sex ratio (male/female$\times$100) fo 38.5 and the fauna of the fly was to 44 species. In the comparision of the individuals of each family collected, Calliphoridae occupied 64% of the total catch, Muscidae 31%, and Sarcophagidae 5%. In the comparision by traps of the numbers of species and individuals collected, 6,729 individuals in 25 species were collected at Trap 1, and 6,636 individuals in 28 species, at Trap 2. The five predominatn spacies, Calliphora lata, Chrysomyia pinguis, Hydrotaea dentipes, Ophyra leucostoma and Muscina angustifrons, consistuted 78.7% of the total collection. In the seasonal prevalence of the total flies from the beginning of March to the end of November, the primary peak of the male appeared in May, and that of the female in April; the secondary peak of the male appeared in September, and that of female in October; and the tertiary peaks of both sexes appeared in July. In seasonal prevalence, the female flies collected significantly outnumbered the male flies, and the numbers of species and individuals were very closely correlated. Although the number of the female flies was somewhat greater than that of the male, the patterns of seasonal prevalence were very similar at Trap 1 and Trap 2 from June to November. The number of the female collected was greater at Trap 1 than at Trap 2 in April, which is the primary peak of overall seasonal prevalence. The characteristics of five predominant species in the collection were summarized, and their seasonal prevalence and monthly change in the composition of flies collected at each trap were also compared.
지룡산에서 부육에 유인포획된 13,365개체의 승족상은 검정파리과 9종, 쉬파리과 17종, 집파리과 18종으로서 총 44종이었다. 과별로 포획된 개체수는 검정파리과가 전체 파리의 64%, 집파리과가 31%, 쉬파리과가 5%였다. 트렙별로 포획된 파리종수 및 개체수를 비교하면 트렙 1에서 25종, 6,729개체가 트렙 2는 28종, 6,636개체가 포획되었다. 우점종으로서 5종의 순위는 큰검정파리 (Calliphora lata), 검정뺨금파리 (Chrysomyia pinguis), 혹다리꽃파리 (Hydrotaea dentipes), 털깜장파리 (Ophyra leucostoma), 붉은종아리큰집파리 (Muscina angustifrons)였고 이 5종은 포획된 전체 파리의 78.7%를 차지했다. 全파리류의 계절적인 발생소장은 3월초부터 11월말까지였고 최대발생 peak는 수컷은 5월, 암컷이 4월이었고 두 번째 peak는 수컷이 9월, 암컷은 10월이었으며 세번째 peak는 암수 다 같이 7월이었다. 계절적인 발생소장에서 수컷보다 암컷의 포획성적이 월등하게 우세하였으며 파리의 종류와 포획 개체수간에는 상관관계가 매우 큰 것으로 나타났다. 트렙 1과 2의 계절적인 발생소장에 있어 6월부터 11월까지는 암컷의 개체수가 수컷에 비해 약간 많은 가운데 페턴이 꼭 같았었는데 4월에 트렙 1의 암컷이 트렙 2의 암컷보다 두드러진 차로서 큰 peak를 이루었다. 이 peak는 지룡산 파리류의 계절소장 전체를 통해서 최대의 것이었다. 포획성적에 우위성을 보인 5종의 종별 발생소장을 비교하였다.
