BLOW FLY (DIPTERA: CALLIPHORIDAE) IN THAILAND: DISTRIBUTION, MORPHOLOGICAL IDENTIFICATION AND MEDICAL IMPORTANCE APPRAISALS NOPHAWAN BUNCHU Department of Microbiology and Parasitology and Centre of Excellence in Medical Biotechnology, Faculty of Medical Science, Naresuan University, Muang, Phitsanulok, 65000, Thailand. *Corresponding Author: Email- [email protected] Received: April 03, 2012; Accepted: April 12, 2012 Abstract- The blow fly is considered to be a medically-important insect worldwide. This review is a compilation of the currently known occur- rence of blow fly species in Thailand, the fly’s medical importance and its morphological identification in all stages. So far, the 93 blow fly species identified belong to 9 subfamilies, including Subfamily Ameniinae, Calliphoridae, Luciliinae, Phumosiinae, Polleniinae, Bengaliinae, Auchmeromyiinae, Chrysomyinae and Rhiniinae. There are nine species including Chrysomya megacephala, Chrysomya chani, Chrysomya pinguis, Chrysomya bezziana, Achoetandrus rufifacies, Achoetandrus villeneuvi, Ceylonomyia nigripes, Hemipyrellia ligurriens and Lucilia cuprina, which have been documented already as medically important species in Thailand. According to all cited reports, C. megacephala is the most abundant species. Documents related to morphological identification of all stages of important blow fly species and their medical importance also are summarized, based upon reports from only Thailand.
