  1. 1. University of SulaimaniaSchool of ScienceDepartment of Biology2nd Class Year Practical Entomology 2011-2012 12th Lab.Insects’ Respiratory Apparatus Lecturer: Farhad A. Khudhur
  2. 2. Objective• This Lab. making the students to be familiar with different insects respiratory apparatus.• Students must know more details about the diversity in respiratory apparatus of aquatic and terrestrial insects.
  3. 3. Respiration• Tracheae – chitinous tubes• Tracheoles – fine, intercellular tubes• Spiracles – openings of tracheae – With closing device – Primitively 1 lateral pair/segment – Sometimes modified • Piercing • Telescoping • “Spiracular gill”• Body Wall – Undifferentiated integument – Tracheal gills
  4. 4. Spiracular Distribution– Polypneustic at least 8 pairs of spiracles (e.g., adults of terrestrial insects)– Oligopneustic – 1-2 pairs of spiracles • Amphipneustic – 1 pr mesothorax, 1 pair post- abdominal (e.g., Trichoptera: Psychodidae larvae) • Metapneustic – 1 pair post-abdominal (e.g., Diptera: Culicidae larvae) • Propneustic – 1 pair mesothorax (e.g., dipterous pupae)– Apneustic – no spiracles (e.g., Ephemeroptera and odonata larvae)
