Abstract

Abstract In order to evaluate the Diptera biodiversity in the Boumerzoug sub-basin, samples were performed at five permanent oueds: El Berda Oued, Boumerzoug Oued, El Guareh Oued, Hmimime Oued, and Sigus Oued. Sampling was carried out monthly during the period from December 2014 to November 2015. The samples were taken using a Surber mesh for the lotic face with size 25 cm * 20 cm * 65 cm, 500 µm net. In total, 53484 individuals comprising 24 families were collected. The Chironomidae family is the most dominant with a population of 43553 individuals (Fc % = 81.43%), followed by the Simuliidae (5137 individuals, Fc % = 9.61%), Psychodidae (1907 individuals, Fc % = 3.57%), Ephydridae (1509 individuals (Fc % = 2.81%) and Sciaridae (313 individuals, Fc % = 0.59%). However the remained families (Culicidae, Asilliidae, Mycetophilidae, Tipulidae, Syrphidae, Tabanidae, Muscidae, Calliphoridae, Ceratopogonidae, Fanniidae, Cecidomyiidae, Anthomyiidae, Sphaeroceidae, Sciomyzidae, Stratiomyidae, and Phoridae) weree poorly represented (between 1 individual (Fc % <0.00%) to 281 individuals (Fc % = 0.53%) were collected with predominance. Finally, compared to the other families, the predominance of the Chironomidae family can be explained by the fact that this family plays an important ecological role in wetlands rich in organic matter, even clearly polluted.

Boumerzoug次盆地的Dipters（君士坦丁-阿尔及利亚）

摘要为了评估Boumerzoug次盆地的直翅目生物多样性，在五个永久性Oued进行了采样：El Berda Oued、Boumerzoug-Oued、El Guareh Oued，Himime Oued和Sigus Oued。2014年12月至2015年11月期间，每月进行一次采样。使用Surber乳液脸网采集样本，尺寸为25厘米*20厘米*65厘米，500µm网。总共收集了53484人，包括24个家庭。摇蚊科是最主要的科，有43553只（Fc%=81.43%），其次是Simuliidae（5137只，Fc%=9.61%）、Psychodidae（1907只，Fc=3.57%），Ephydridae（1509个个体（Fc%=2.81%）和Sciaridae（313个个体，Fc%=0.59%）。然而，剩下的科（Culicidae、Asilidae、Mycetophilidae、Tipulidae、Syrphide、Tabanidae、Muscidae、Calliphoridae、Ceratogonidae、Fannidae、Cecidomyidae、Anthomiidae、Sphaeroceidae、Sciomzidae、Stratomyidae和Phoridae）的代表性较差（1个个体（Fc%<0.00%）至281个个体（Fc%=0.53%）被收集，具有优势。最后，与其他科相比，摇蚊科的优势可以解释为该科在富含有机物甚至被明显污染的湿地中发挥着重要的生态作用。
