The house mouse, Mus domesticus, has been reported to cause substantial pre-harvest yield losses of grain crops (e.g.; Mwanjabe et al.2002; Singleton 2003; Stenseth et al. 2003; Brown 2004). The relationships between yield losses and number of mice have not been studied systematically (Brown 2001; Hone 2004). By quantifying and modelling the relationship between different densities of mice and yield losses, appropriate ecologically and economically-based management strategies can be established. This has been examined by using 16 rodent proof enclosures (pens) each one 225 m2 in size on Gatton campus, UQ, QLD, Australia from December 2002 to May 2004. The pens allow us to determine and quantify the relationship between different numbers of adult mice which have been introduced in 4 different densities to each 4 pens and yield losses caused by mice to particular crops types for the period of 7 weeks from milky stage to ripening stage. Crop type examined was sorghum.
