There are a variety of widely practiced molecular genotyping used in a forensic entomological investigation, which can be beneficial when it comes to using DNA-based specimen identification, as well as the identification of insect gut contents, and the characterization of the population of genetic structure of forensically insect species. As with most of the live sciences, forensic entomology increasingly uses the tools of molecular biology with the impact of attracting researches and performing a standard forensic genetic technique such as micro-satellite and mitochondrial DNA sequencing on a wide variety of animal species. Species determination is the only application of the genotyping that is used in forensic entomology. In the first step of forensic entomological analysis, it is usually crucial to have an accurate identification due to the…show more content…
However, the mitochondrial DNA (mtDNA) has taken the leading role in insect genomic studies, where it made it easy to get mtDNA sequence data from many previously unstudied insect species. Nevertheless, recently developed species-diagnostic methods, such as microarrays, are used for non-insect class, and such method will have a greater role in forensic entomology due to variety of oligonucleotide probes that are placed on a single microarray chip. A single microarray is capable of performing virtually every genotyping task needed for a forensic insect specimen. It is important for forensic entomologists to detect and use geographic variation, because it might be important to repeat many experiments, at new locations, since reference data developed in one place are not
