Abstract: Apart from observations on the hatching of eggs at different temperatures (Crofton, 1965) and the rate of larval development at “room temperature” ( Andrews, 1939), the biology of the free-living stages of Cooperia curticei has not been studied. This lack of attention is probably due to the low pathogenicity of C. curticei for sheep ( Andrews, 1938; Ahluwalia and Charleston, unpublished data) and the small infestations that are usually reported (Crofton, 1963). In New Zealand, however, heavy infestations of C. curticei commonly occur in sheep. This paper describes laboratory and outdoor studies on the development of the free-living stages of C. curticei.
