LIFE CYCLE

  • Eggs are passed in the faeces of host. The development and bionomics of the larvae are similar to Strongylus spp.
  • L1 emerges from the eggs in about 20 hrs and L1 to L2 in about 3 days. Infective stage is reached in about 6 to 7 days of time.
  • Infection of final host by ingestion of infective larvae along with herbage. Exsheathment occurs in small intestine.
  • L3 penetrate the intestinal mucosa and form a nodule in which the L3 moult to become L4 in about 4 days.
  • Then the L4 enters into the lumen of the intestine and pass to the colon where L4 moult to become L5 and reach maturity in 41 days.
  • Eggs are strongyle type.
