Abstract
To analyse the relationship between the density of Thrips palmi and the rate of copulation, 4 plots with different densities of T. palmi were set up in plastic houses in which cucumber was cultivated. Each density level was maintained by spraying insecticides. In plots with low densities, the rate of copulation was also low, and the relationship could be expressed as y=1-e-20.93x(y: rate of copulation, x: number of adult females per leaf). The low density effect strongly influenced the population fluctuations of T. palmi.
