Article Synopsis
  • - In medical, veterinary, and forensic fields, whole-image analysis using image data has proven to be a cost-effective method for identifying different fly species, particularly focusing on their wing images.
  • - Krawtchouk moment invariants are employed to highlight specific biological features in these wing images, enabling the classification of 759 fly specimens from various families and species using advanced machine learning techniques.
  • - The study achieved impressive accuracy rates of 98.56% at the family level and 91.04% at the species level, suggesting a reliable approach for ongoing automated identification of flies important to these fields.

A study of entomological specimens recovered from 117 human corpses in 114 forensic cases was conducted in Taiwan between 2011 and 2018. The comparisons and discussions of the entomological data were based on the locations (indoor vs. outdoor), environments (urban vs.

Insect larvae and adult insects found on human corpses provide important clues for the estimation of the postmortem interval (PMI). Among all necrophagous insects, flesh flies (Diptera: Sarcophagidae) are considered as carrion flies of forensic importance. DNA variations of 17 Malaysian, two Indonesian and one Japanese flesh fly species are analysed using the mitochondrial COI and COII.

The mitochondiral DNA region encompassing the cytochrome oxidase subunit I (COI) and cytochrome oxidase subunit II (COII) genes of two Malaysian blow fly species, Chrysomya megacephala (Fabricius) and Chrysomya rufifacies (Macquart) were studied. This region, which spans 2303bp and includes the COI, tRNA leucine and partial COII was sequenced from adult fly and larval specimens, and compared. Intraspecific variations were observed at 0.
