Role of bioclimatographs in forecasting of strongyle infection in Rajasthan

Abstract

The present communiqué describes the role of bioclimatographs in forecasting the periods suitable for translation of predominant nematode parasite of sheep (Haemonchus contortus) in Rajasthan. Bioclimatographs were useful in predicting the periods that are suitable for translation of exogenous stages of H. contortus in both arid and semi-arid environment with resultant peak of infection in host. Further, the study provides the possibility that climatic consideration in combination with grazing practices can be taken into account in evaluating expected level of refugia and thus treatments can be avoided at times when refugia are likely to be small. Thus, integration of climate and biology of parasite in the form of bioclimatograph may strengthen our tool box in combating the menace caused by gastrointestinal parasites.
