Decomposition and succession of coleoptera on two dog corpses in Constantine, northeastern Algeria

Among the different works that have been developed by entomologists concerning the decomposition of corpses, we have noticed that the gradual arrival of insects on a decomposing dead body doesn’t obey the scheme of the eight squads.
In Algeria, works on forensic entomology are in their first steps, especially for Coleoptera on which no work has been done yet. That’s why we have chosen to deal with this subject, by choosing two dead animals, an adult dog and a puppy.
The study was carried out in spring, in an open area localized near the Biosystematic and Ecology of Arthropods laboratory, Chaabat Erssas Constantine, Algeria. The two corpses were put in two separate cages to protect them from any possible except beetles or flies. Already a few hours after the two cadavers have been brought into their position they were visited by insects which started with egg-deposition. After the capture of the insects, the identification revealed that they belong to two major insect orders which are flies (Diptera) and beetles (Coleoptera). These insects partly constitute the necrophagous fauna.
Our daily sampling has allowed us to collect a total of 724 specimens on the corpse of the adult dog, 58% of which belong to the order Diptera and 42% belong to the order of beetles. On the cadaver of the puppy, we identified 165 specimens of which 26% belong to the order Diptera and 74% belong to the order of Coleoptera.
The results show a fine, dissimilar diversity of necrophagous beetle insects on the corpses of the adult dog compared to the puppy belonging to different families, genus and species.
