PREDICTIOG POPULATION OF HAEMONCHUS CONTORTUS INFECTIVE LARVAE ON PASTURE FROM METEOROLOGICAL DATA
Meng Xiuzhen;Shen Jie(Shanghai Institute of Animal Parasitology,CAAS, Shanghai 200232)
A simulation model which described the population dynamics of Haemonchuscontortus infective larvae on pasture from meteorological data was constructed. Rate of development of the nematode from egg to the infective stage at different constant temperatures andhumidities and on pasture and the population dynamics of fsecal eggs in every month wereused.The effect of temperature,humidity, season and host were estimated. The population dynamics of infective larvae predicted are suituble to that of adults in sheep and goat.The model could be used in different climate region and will lead to economically efficient controlmeasures.
