Abstract: Conditions appear ideal for annual plagues of house mice in irrigated rice growing areas of Australia, yet plagues in these areas usually coincide with those in the dry farms. In an irrigated rice crop near Jerilderie, New South Wales, we examine in detail the demography of an incipient plague population of Mus. Breeding occurred from winter 1983 to autumn 1984 and the population increased from low levels to plague levels (2500/ha) by May. We found no evidence for a rigid territorial social organization. Dispersal of tagged animals was low throughout the breeding season, yet between 60 and 76% of the trappable population was new each trapping session. Testosterone levels increased when the average male body weight was low, suggesting that social suppression of reproduction was not occurring. We conclude that plagues in these areas can develop within approximately 12 months from the onset of drought breaking rains.
