Question 52

Describe the larval migration pattern of Oestrus ovis (Nose bot)

Answer 52

Eggs are laid in the nasal area. Larvae migrate up the nasal passage into the sinuses where they mature. They then migrate back down to the nasal opening where they are sneezed out. In the envirnment they pupate, hatch and emerge as adults

Question 53

Describe the larval migration pattern of Hypoderma bovis/lineatum (Warble fly)

Answer 53

Eggs are laid on the hair follicles. After a few days they hatch and the larvae penetrate the skin and enter the body. They migrate toward the dorsal aspect of the animal near the spinal cord where they get into the subcutaneous layer of the skin until they pupate (causing "warbles" or swelling in the skin) where they hatch and the fly exits through the skin. \*Less commonly larvae can be ingested and migrate to the trachea where they are coughed up and swallowed\*

Question 54

Describe the larval pattern of the Gastrophilus intestinalis/nasalis or Bots

Answer 54

Eggs hatch due to either stimulation or spontaneously, and the larvae penetrate the buccal cavity and migrate to the stomach. They attach to stomach lining where they mature and detach, exiting the host through feces. Once they exit they pupate and hatch as adults
