Life Cycle:

Species of the Cyathostominae have a direct lifecycle, with no intermediate host.The third larval stage (L3) develops in feces deposited iin areas where animals are grazing. The ingested larval nematodes continue their maturation through subsequent sthegs to the adult and new eggs may be deposited in feces in 5-6 weeks.  Eggs hatch in the feces and larvae develpo to the third stage when they enter an apparent dauer stage surrounded by an extra protective cuticle. They are able to survive in the grazing area for prolonged periods. Once ingested, the encysted L3 nematodes may remain encysted in the intestinal wall for periods up to 2 years. In temperate climates, the nematodes tend to enter the dauer stage during cooler months while in tropical areas the dauer stage may be entered in the summer as a protection against heat (Corning, 2009).
