abstract
This study aims atrevealing more information about the seasonal variation of the necrophagous fauna biodiversity. Three entomological experiments were carried out in Algeria, in an open space near the Biosystematic and Arthropod Ecology Laboratory in Constantine at Chaabat Erssas, during three seasons (spring, summer, and autumn) of the year 2012/2013. They allowed us follow the decomposition of three dead-dog corpses. The results showed that the scavenger insects studied in spring were the most diverse one with 21 taxa (Diptera 57.73%, Coleoptera 41.16%, and Hymenoptera 1.1%) as compared to summer (9 taxa) (Diptera 77.77%, Coleoptera 22.22%) and autumn (7 taxa) (Diptera 81.03%, Coleoptera 18.96%). Favorable weather conditions (temperature) partly explain these results.
