title: Factors affecting recovery of Dictyocaulus viviparus third stage larvae from herbage and growth of Pilobolus on dung pats.
abstract: Significantly greater Dictyocaulus viviparus stage three larval recoveries from herbage samples adjoining first stage larval infected dung pats with Pilobolus, and the effects of biotic and mechanical factors on dung pat integrity supported previous findings. Several meteorological factors including sunshine hours, relative humidity, rain total and wind speed showed significant correlations with growth of Pilobolus on dung surfaces. The influence of monitored variables on the recovery of third stage larvae from herbage and the growth of Pilobolus was modified by height of the sward surrounding the dung pat. Multiple regression analysis showed that 60 per cent of variation in D viviparus third stage larvae recovery from herbage was accounted for by known variables.
