Summary
The survival ofHaemonchus contortus infective larvae on pasture and soil was studied over a period of 12 months in the Baghdad area. Infective larvae were found on herbage and soil at all times except in the summer months. During autumn and winter infective larvae in pasture survived for periods of up to 32 weeks. Little larval migration into soil was observed during this study and larvae did not survive for long in the faecal pellets during the summer.
Résumé
La survie des larves infestantesd'Haemonchus contortus sur les pâturages et le sol a été étudiée dan la région de Baghdad sur une période de 12 mois. On a trouvé des larves infestantes sur les herbes et le sol à toutes époques sauf pendant les mois d'été. En automne et en hiver les larves infestantes survivent jusqu'à 32 semaines sur le pâturage. Dans cette étude, on n'a observé que peu de migration des larves dans le sol; elles ne survivent pas longtemps dans les fècès pendant l'été.
