本文报道了广东省东莞市太平港媒介生物的区系分布与密度指数,作者于1994年5月经初步调查,共发现褐家鼠一种,其密度为10.28％,臭鼩鼱一种,密度为9.35％,数量仅次于褐家鼠广泛分布港区室内外。蚊类共诱捕到12种,其中库蚊属占61.70％,为优势种,蝇类共诱捕到11种,其中以丽蝇科最多,占89.99％,为优势种。调查示知本港区媒介生物密度指数较高,应加强防制。
This paper reports the distribution and density index of vector organisms in Taiping Port, Dongguan City, Guangdong Province. After a preliminary investigation in May 1994, the authors found a species of Rattus norvegicus with a density of 10.28% and a density of 9.35%, second only to the number of Rattus norvegicus widely distributed in the port indoor and outdoor. Mosquitoes were traced to 12 species, of which, Culex was 61.70%, dominant species, and flies were traced to 11 species, of which, Phalaenopsis was the most, accounting for 89.99%. The survey revealed that there is a high incidence of vector bio-density index in Hong Kong. We should strengthen our prevention and control.
