Blowflies have a double-edged relationship with animals. On one hand, blowfly maggots cause serious myasis in animals, On the other hand their ability to cause myasis may be used to cure chronic wounds in precious animals. Life cycle of Chrysomya albiceps (Ch. albiceps) was investigated under controlled conditions of 26 ± 2 °C, 55 ± 10% relative humidity (RH), and 12L:12D photoperiod, and the larvae were fed on beef meat. Whole body maggot extracts were prepared by different methods and their protein content and electrophoretic protein patterns were compared. It was found that the post-embryonic development of Ch. albiceps took about 8.97 days with a significantly higher females ratio (P < 0.0001) which also had a longer life span than males (P = 0.0024). Maggot extract prepared by snap freezing in liquid nitrogen yielded the highest protein content and its amino acids were separated. So, the extraction technique has a great effect on the protein content which is essential in the future uses of maggot extract. Further investigations on the bioactive components of maggot extract are recommended.
