The Sloane, Cook and King study that valued the damage caused to pastures by redlegged earth mite and other pests is limited because of the lack of economic justification given for the assumed impacts of the pests on profitability. This study provides a preliminary estimate of the potential value of eliminating Halotydeus destructor from pastures in a region of Western Australia and it identifies the information required to make a better estimate. Gains from controlling H. destructor were 49 Australian dollars per hectare of pasture, and this is much higher than the level assumed by Sloane, Cook and King. More information is required on the effects of H. destructor on pasture and crop production before results can be extended to farmers, and further analyses are required to highlight the potential of different control strategies.
