Abstract The study dealt mainly with determining the necrophilous flies successive waves inhabiting decomposing carrions of exposed European rabbits (Oryctolagus curicullus Linnaeus). Eight rabbits were monitored as surrogate models and divided into two main groups; the first group was killed by the administration of warfarin rodenticide and the second was asphyxiated via hanging as a control. Experiments were carried out during spring 2016 in Cairo, Egypt. The fresh, bloated, active decay, advanced decay and skeletonization stages of decomposition were obvious and designated in all carcasses. The duration of each stage was recorded. A total of 12481 individuals (immature stages and adults) were collected and classified into 7 orders, 28 families and 44 species. The carrion-feeding maggots were potential reservoirs of warfarin administrated to the rabbits. Warfarin was recovered by High-Performance Liquid chromatography (HPLC) which signifying the role of maggots as poisoning indicators. Warfarin was found to accelerate the rate of maggot development and cause abnormalities and malformations in the emerged adults. Dipteran larvae were collected for the isolation and identification of bacteria and fungi that may act as speeding-up factors for both the decomposition process and the developmental stages of larvae.
