Current research Minimising risk Extensive research is being undertaken into the ecology of the Processionary caterpillars to identify ways horses are exposed to caterpillar hairs and to develop strategies to allow broodmare owners and managers to minimise the risk of exposure. Role of other hairy caterpillars Ongoing research is i nvestigating the role of other hairy caterpillars as a cause of EAFL using a guinea pig model. Many species carry very similar setae! Acknowledgements: The research into Ochrogaster lunifer and its role in abortion in mares has been carried out by the University of Queensland and was supported by RIRDC and the Hunter Valley Equine Research Foundation and ongoing research into caterpillar ecology through the Australian Research Council and the Hunter Valley Equine Research Foundation.

Silk-like webbing leading between processionary caterpillar nests and their feeding areas in the canopy. While trunk or ground nests may not be readily seen, the webbing is an obvious indicator of an active nest at the tree. July • August • 2017 • The Australian Quarter Horse Magazine • Page 21
