Surface ultrastructure of third-instar Megaselia scalaris (Diptera: Phoridae).
We describe some ultrastructure of the third-instar Megaselia scalaris (Diptera: Phoridae) using scanning electron microscopy, with the cephalic segment, anterior spiracle and posterior spiracle being emphasized. This study provides the taxonomic information of this larval species, which may be useful to differentiate from other closely-related species.
متن کاملObservations on first and second-instar larvae of Megaselia scalaris (Loew) (Diptera: Phoridae).
The ultrastructure of the first and second-instar larvae of Megaselia scalaris (Loew) was studied using scanning electron microscopy (SEM). Significant changes in morphological features were observed in the anterior and posterior spiracles, but only minimal changes in the labium and mouthhooks were seen. The ultrastructure of M. scalaris larvae not only provides chronological transformation of ...
متن کاملDevelopmental Variation of Indian Thermophilic Variety of Scuttle Fly Megaselia (Megaselia) scalaris (Loew, 1866) (Diptera: Phoridae) on Different Substrates
The scuttle flies (Diptera: Phoridae) are important in forensic dipterology, because of their necrophagous habit. They are amongst the first wave of insects visiting human corpses in mechanically barricaded environments; hence their immature stages are generally used for estimation of PMI. The effect of different substrates commonly used for developmental studies was studied to analyze the vari...
متن کاملA case study of Megaselia scalaris (Diptera: Phoridae) causing ocular myiasis in a western hognose snake.
Late instar larvae of the scuttle fly, Megaselia scalaris Loew, were found near the right eye of a live captive-reared western hognose snake, Heterodon nasicus Baird and Girard. Dissection and removal of the snake's dorsal cranial bones revealed tissue degradation of the infected eye, the optic nerve, and the brain case; we suggest that these factors contributed to the death of this snake. This...
متن کاملEffects of Temperature and Tissue Type on the Development of Megaselia scalaris (Diptera: Phoridae).
The scuttle fly, Megaselia scalaris (Loew) (Diptera: Phoridae), is of medical, veterinary, and forensic importance. In the case of the latter, M. scalaris is commonly associated with indoor death or neglect cases of humans or household animals, and its larvae are useful in determining time of colonization (TOC). This study is the first to examine the effects of different temperatures and tissue...
