• One hundred and twenty five females of the citrus red mites, Panonychus citri (McGREGOR), were inoculated on a central sapling in a group of itrus saplings (5×5 saplings) in the greenhouse and the field (clumped inoculation). The same number of females were inoculated uniformly on each of 25 saplings in the greenhouse (uniform inoculation). In the greenhouse, the number of mites increased almost exponentially and then decreased drastically. In the field, however, the patterns of the population growth were remarkably different between saplings. Exponential growth was observed only on two saplings in the field. Spatial distribution pattern in the uniform inoculation was slightly contagious while that in the clumped inoculation changed remarkably with time. This phenomenon was caused by the intermittent reproduction and dispersal of mites on the saplings. The instantaneous rates of reproduction (γ_0) calculated for the data in the greenhouse were higher than that in the field and the former were similar to the rates which had been estimated in the cirtus orchards.
