Decomposition and dipteran succession on buried rabbits carcasses.

The rabbit carcasses used in this study were buried at depths of 20 and 40 cm, were examined to construct a fly succession database on buried carrion in Riyadh, Saudi Arabia. Twenty-four rabbits were buried, 12 at 20 cm and 12 at 40 cm. One carcass at each depth was exhumed at 10-day intervals up to 120 days. The degradation rate varied among the carcasses. Differences in species and their colonization were also found in the superficial and exhumed carcasses. Eleven species of flies were recorded on carcasses interred at a depth of 20 cm and seven species at 40 cm, while 13 species were recorded on the carcasses over the top of the soil. Species sp (Diptera: Calliphoridae), Thomson, and (Wiedemann) (Diptera: Sarcophagidae) were dominant at both depths, while (Wiedeman), (Macquart) (Diptera: Calliphoridae), Linnaeus, and Wiedemann (Diptera: Muscidae) were dominant in surface carcasses. (Loew) ((Diptera: Phoridae) is a common and typical forensic indicator that was found in the decay/advanced decay and dry stages at a depth of 20 cm. These findings are possibly useful in forensic investigations involving buried bodies in Riyadh, Saudi Arabia.
