Editing Forensic entomology (section)

=== DNA analysis ===
Modern forensic entomology now relies heavily on DNA analysis as a fundamental tool for accurately identifying insect species and gaining important insights into their interactions with human remains. Using this method, DNA is extracted from insect specimens discovered at crime scenes and compared to databases containing known DNA sequences. Forensic entomologists can verify species identification, identify the existence of particular species linked to decomposition, and even establish a connection between insects and particular geographical areas through the examination of insect DNA.<ref>{{cite journal | vauthors = Wells JD, Stevens JR | title = Application of DNA-based methods in forensic entomology | journal = Annual Review of Entomology | volume = 53 | issue = 1 | pages = 103–120 | date = 2008 | pmid = 17685848 | doi = 10.1146/annurev.ento.52.110405.091423 }}</ref>

The identification of insect stomach contents is one of the main uses of DNA analysis in forensic entomology. Investigators can ascertain the insect's most recent meal by sequencing the DNA contained in the gut of maggots or other insect larvae discovered on a body. When determining the postmortem interval (PMI) or locating possible sources of contamination or infection, this information might be extremely important.<ref name="Amendt_2007" />

The study of insect dispersal patterns and colonization behaviour has also been transformed by DNA research. Researchers can deduce patterns of travel and colonization by examining the genetic variety of insect populations. This can provide important insights into the origin of insect specimens found at crime scenes or the transportation of a body.<ref name = "Wells_2001">{{cite journal | vauthors = Wells JD, Sperling FA | title = DNA-based identification of forensically important Chrysomyinae (Diptera: Calliphoridae) | journal = Forensic Science International | volume = 120 | issue = 1–2 | pages = 110–115 | date = August 2001 | pmid = 11457617 | doi = 10.1016/S0379-0738(01)00414-5 }}</ref>

In general, DNA analysis has improved forensic entomology's accuracy and dependability significantly, allowing investigators to obtain previously unobtainable specific information from insect evidence.
