Abstract: The state of our knowledge of the relation of weather and climate to the development and survival of ruminant strongylorid nematode larvae on pasture is reviewed. The use of parasite profiles to compare parasite species distribution in different localities and under different conditions is suggested. These are bar graphs depicting the relative percentages of the diffeent nematode genera or species, based on a figure of 100% for the total number of strongylorid nematodes and recording non-stroingylorids in terms of this total. Climate is related to nematode epidemiology by use of bioclimatographs in wihich mean monthly temperature is plotted in a closed curve against total monthly precipitation. The limits for optimum pasture transmission of Haemonchus are taken to be 5 cm. (2 inches) or more precipitation and 15 to 37C. (59 to 99F.) mean monthly mean temperature. The limits for optimum pasture transmission of Trichostrongylus and Oestertagia are taken to be 5 cm. (2 inches) or more precipitation and 6 to 20C. (43 to 68F.) mean monthly mean temperature. Potential evapotranspiration is an important factor in nematode epidemiology. It determines the soil moisture supply, which in turn has a marked effect on larval development and survival. Potential transmission periods based on temperature and soil moisture were calculated. The potential transmission period of Haemonchus is taken to be at a mean monthly mean temperature of 15 to 37C. (59 to 99F.) when the soil water deficiency is not more than 2.0 cm. (0.8 inches). That of Trichostrongylus and Ostertagia is taken ro be at a mean monthly mean temperature of 6.
