We report a forensic entomology case associated with human myiasis in Chiang Mai Province, northern Thailand. The remains of a 53-yr-old-male were concurrently infested with third instars of the two blow fly species, Chrysomya megacephala (F.) and Chrysomya rufifacies (Macquart), near a severe tumor lesion presented on the lower right leg. The presence of third instars, approximately 5 d old, o...

Myiasis maggots were isolated from the cancerous wounds, when the patients reported to the Department of ENT-OPD, JIPMER, Pondicherry. Maggots were identified to Chrysomyia bezziana based on characteristic patterns of posterior and anterior spiracles. Although the categories of cancer wounds were different, invasions were due to C. bezziana, which is very common in suburban areas of Tamil Nadu ...

Comparison of prestomal teeth of adult Chrysomya megacephala, Chrysomya rufifacies, Chrysomya nigripes, Lucilia cuprina, Parasarcophaga dux and Musca domestica was accomplished by use of scanning electron microscopy. The prestomal teeth of C. megacephala, C. rufifacies, L. cuprina and P. dux are all similar in appearance in having various degrees of bifurcation at their tips. In contrast, the t...

This paper presents complete mitochondrial genomes for the sheep blowfly, Lucilia sericata (Meigen), and the secondary blowfly, Chrysomya megacephala (Fabricius). Both L. sericata and C. megacephala had standard dipteran-type mitochondrial genome architectures and lengths of 15 945 bp and 15 831 bp, respectively. Additionally, C. megacephala possessed a tRNA duplication either side of the D-loo...

The investigation of the genetic variation and population structure of Chrysomya species is of great interest for both basic and applied research. However, very limited genetic information is available for this genus across its geographical distribution. Here, we describe 12 polymorphic microsatellite loci isolated from Chrysomya putoria with expected heterozygosities ranging from 0.1402-0.8312...

A forensic entomological study was conducted using monkey carcasses (Macaca fascicularis Raffles) that were placed in either an outdoor or indoor environment at a coastal area in Tanjung Sepat, Selangor, Malaysia during May until August 2008. We collected pupae of Chrysomya rufifacies (Marquart) from the carcasses and kept them individually. The emergence of 13 parasitic microhymenopteran, from...

Larvae of Chrysomya albiceps (Wiedemann) and Chrysomya putoria (Wiedemann) were reared on liver tissues from a rabbit that had a malignant tumor in the thoracic cavity. Larval rearing of both blowfly species was conducted at ambient temperature. Larvae that fed on tissues from the rabbit with the tumor developed at significantly faster rates than those feeding on tissues from the control animal.

Screwworm myiasis, caused by infestation of even minor wounds by the obligative parasitic larval stages of the New World screwworm (NWS) (Cochliomyia hominivorax) or Old World screwworm (OWS) (Chrysomya bezziana) flies, is a major cause of livestock morbidity and mortality in tropical and sub-tropical regions of the world. The two parasites occur in different hemispheres but are remarkably homo...

In this study we investigated predation rates on third instar larvae of Chrysomya putoria and C. megacephala by third instar larvae of C. albiceps in a two-choice situation. The highest predation rate occurred on C. putoria larvae and this result is compared to previous experiments, in which C. macellaria larvae were present. Our results suggest that, when C. macellaria is absent C. albiceps la...
