Abstract: The literature pertaining to the bionomics of some of the most important tetranychids is reviewed. Considerable attention is paid to the possibilities of spider mites reaching pest levels as a result of environmental factors. It is concluded that more information is needed on economic injury levels of various species on different crops and under various climatic conditions. The influences of cultural practices and their interactions as related to population development of tetranychids also need more study. Furthermore, work is needed on the influence of climatic conditions on development of tetranychid mite populations together with possible predictability of outbreak situations. Finally, we need to know more about the fundamental relations between the host-plant quality and spider mite development, and the impact of spider mites on the development of their host plants.
