Forensic entomology. (Junior Division).

This research was conducted to (1) rear Sarcophaga bullata (blowfly), and observe the metamorphic phases, (2) study the phases of decomposition due to the feeding of the S, bullata on the beef liver, and (3) determine if varied temperature has an effect on the development of S. bullata when determining the post-mortem interval while being used in forensically involved cases. Three different microclimates were simulated in incubators at 50, 70, and 90 degrees Fahrenheit. S. bullata was inoculated onto the liver during the larval stage. Progress was inspected twice daily for four weeks. Results indicated that the 70 and 90 degree Fahrenheit microclimate allowed quickened maturation and decomposition rate of the liver, as compared to the cooler 50 degree Fahrenheit environment. In conclusion, it was determined that environmental temperatures do have a large impact on fly development when determining post-mortem interval when Forensic Entomology plays an important role in solving a case.
