In tropical populations, such as in Brazil , fertility is also lower in areas with high densities of larvae, where many in one small area compete for the same food source. A correlation between wing size and temperature as well as tibia size and temperature has also been found in this species. There was a similar relationship between wing and tibia size and fecundity.

GS Vijay Kumar, E-mail: moc. This article has been cited by other articles in PMC. Abstract Myiasis is an opportunistic infestation of human and vertebrate animals with dipterous larvae.

Oral myiasis is a rare condition associated with poor oral hygiene, mental disability, halitosis and other conditions. We present a case report of an adult mentally challenged woman with extensive necrotic oral lesion burrowing into the hard palate through which three live maggots larvae were seen emerging out. The larvae were removed using forceps and the patient was treated with oral ivermectin. The maggots were identified as larvae of the Chrysomya bezziana fly. Myiasis is common in the rural population living in close proximity to live stock.

Myiasis is classified clinically as specific, semi-specific and accidental and anatomically as intestinal, nasal, cutaneous, ophthalmic, oral and urogenital. Oral myiasis was first described by Laurence in Presence of necrotic tissue and bad oral hygiene attracts the flies leading to oviposition.

We are reporting a case of oral myiasis due to Chrysomya bezziana in a mentally challenged patient having extensive necrosis of the hard palate and gums. CASE REPORT A year-old mentally retarded female patient belonging to low socioeconomic status presented to the dental outpatient department with tooth ache in the right maxillary region and generalized gum bleeding of 4 days duration.

She had poor oral and personal hygiene. On examination, there was generalized gingival enlargement with bleeding from the gingival sulcus. A gape in the palatal flap covered with necrotic tissue was observed.

Mouth breathing, severe halitosis and periodontal disease were also noticed. Upper right incisor and right canine were missing.

Chrysomya megacephala (Fabricius, 1794)

Thick Setae on the meron Plumose arista Keep in mind, however, that not all species will conform completely to these guidelines. Adults feed on many things including decaying matter, excreta, and flowers. In their six-week lifespan, specific length may differ as a result of temperature, weather, etc. The species Chrysomya bezziana , for example, lay their eggs exclusively on live mammals. And, as with many fly genera primary and secondary myiasis is possible but unlikely. A Chrysomya rufifacies larva The genus Chrysomya contains 12 species, [3] several of which cause primary and secondary myiases of domestic animals.
