Effect Of 17a - Ethynylestradiol On The Pupation Rate, Emergence Rate, And Sex Ratio Of Phormia Regina (Calliphoridae), Bethany K. Hoschar

Honors Theses

After death, blowflies are attracted to decomposing remains for feeding and reproduction purposes. Since blowflies are usually the first species to colonize a set of remains, they are important to forensic scientists when estimating the time since death. Using the knowledge of the life cycle of a blowfly and any interferences of the environment that can affect the development, forensic entomologists can estimate the time since the arrival of blowflies, otherwise considered time since deposition. This research investigated how a specific estrogen, 17 a-ethynylestradiol, present in pollutants affects the development time of blowflies, and therefore the time since death estimation. …
