Abstract
Seasonal densities and vertical distribution of soil microarthropods were studied in a coffee plantaban in the Central Plateau of Costa Rica (1130 m) from March 1977 to February 1978. The different groups show a variable response to climatic conditions: Collembola, Pretura, Symphila and Acarina seem to be the most susceptible to rainfall. On the contrary, Coccoidea and other groups do not show a clear relation with this climatic factor. The density of coffee plants seems to be of great importance in determining the distribution of Coccoidea.References
