Diptera- Nonbiting Muscoids Flashcards
What family do muscoid flies belong to?
Muscidae
Three morphological features muscoid flies have
Adult fly will possess freely movable head
Adult fly has oval abdomen covered sparsley with stout bristles
Muscoid flies have MAGGOT as larval stage
Two types of muscoid flies
Non-bting (sponging mouthparts)
Biting (bayonet mouthparts)
The non-biting muscoid flies we studied
Musca domestica
Musca autumnalis
Lucilia
Calliphora
Phormia
Phaenicia spp
Sarcophaga spp
Musca domestica AKA
Housefly
“synanthropic” fly
Musca domestica host
Humans and feces of wild/domestic animals
Musca domestica habitat
Feed on feces then human food
FILTH FLIES
How to ID Musca domestica physical features
Medium sized nonmetallic
Mouse gray/dark gray
4 Longitudinal stripes on thorax
No piercing mouthparts-suck or lap semi-liquid food
6 hairy legs with pads at secrete sticky material that helps fly to collect (transmits pathogens)
No mandibles/maxilla so can only drink food
How to ID Musca domestica by internal features
Vomits digestive enzymes from stomach to digest food
Labium that ends in sponging organs, labella
Bottom of labella are pseudotracheae whih serves as “sponge” and capillary action
Purpose of labella
Assits movement of semi-liquid to labium (tongue)
Importance of Musca domestica
- Flys on food and feces: picks up pathogens
- Vomit-drop feeder
- Transmits:Shigella, Salmonella, E.coli, Entamoeba histolytica and Giardia, ascarids, tapeworms
LC of Musca domestica
Complex metamorphosis
- Eggs only laid on feces
- Eggs can be laid on open wounds too=MYIASIS
