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.
