Abstract
Extract
Inhibited development of Haemonchus contortus at an early fourth larval stage has been reported frequently both in New Zealand (McKenna, Citation1973a; Brunsdon, Citation1973) and elsewhere (Muller, Citation1968; Connan, Citation1968, Citation1971; Blitz and Gibbs, Citation1972a, Citationb; Ayalew and Gibbs, Citation1973) and although it is generally accepted that such larvae are capable of eventual resumption of development (Blitz and Gibbs, Citation1971a), relatively little is known regarding their persistence in sheep.
