Influence of microbial inoculant on the oviposition and completion of life cycle of chrysomya megacephala and chrysomya rufifacies infesting rabbit carcasses

Considering any surrounding factors as well as the cunning use of microbial inoculants to cover the smell of decomposing bodies could potentially alter (delay or speed up) the time of initial oviposition and developmental rate of insects infesting the corpses, thereby resulting in erroneous estimati...

This research was conducted to assess the influence of a commercially available microbial inoculant (EM.1®) on the initial oviposition and developmental rate that lead to completion of life cycle of the two prevalent necrophagous flies (Chrysomya megacephala and Chrysomya rufifacies) in Malaysia infesting rabbit carcasses.
