The Phylogenetic Relationship within Diptera

Diptera

• True flies di- two, pteron- wing gt single pair
  of wings
• One of the four largest groups of living
  organisms
• Over 120000 kinds of flies
• Importance transmit disease, model organisms,
  forensics.

3
Families Under Study

• Tephritidae ( fruit flies) Ceratitis capitata
• Calliphoridae (blow flies) Chrysomia putoria,
  Lucilia sericata
• Oestridae (warble flies)Dermatobia hominis
• Drosophilidae (pomace flies) D. mauritana,
• D. Melanogaster
• Muscidae (house flies) Haematobia irritans

4
Tephritidae (fruit flies)

• Ceratitis Capitata- Mediterranean fruit fly
• Damage to wide
• Range of fruit crops
• Larvae laid in fruit

5
Calliphoridae (blowflies)

• Chrysoma putoria-
• Screw-worm fly
• Parasite of worm blooded
• animals
• Lucilia sericata-sheep
• blowfly
• Used in maggot therapy

6
Oestridae (warble flies)

• Dermatobia hominis-
• human botfly
• Attack humans
• Larvae develops in
• subcataneous layer of skin

7
Drosophilidae (pomace flies)

• D.mauritiana
• D.melanogaster-fruit fly
• common model organism

8
Muscidae (house flies)

• Haematobia irritans-
• horn fly
• Lay eggs in cow manure
• Potential danger to
• livestock (infection
• loss of blood from bites)

1997- Knut Rognes

• Adult and larval
• characters
• Parsimony-
• trees of maximum
• total fit (Pee-Wee)

11
2000, Alberto Piccin group

• Analyzed amino acid sequence
• of per gene
• Used PAM distance matrix
• to obtain the tree

12
2003, Jamie Stevens

• Phylogeny constructed by
• parsimony and maximum-
• likelyhood analyses of
• 2215 28S rRNA nts.
