Climatic similarity has been the primary parameter considered in the selection of sites for the collection and release of natural enemies in classical biological control programs. However, acknowledging the relevance of the composition of biological communities can be essential for improving the record of successful biocontrol projects, in relation to the proper selection of collection sites. We present in this paper an analysis of the plant and mite assemblages in cassava fields of northeastern Brazil. Such analysis is suggested as an additional criterion for the selection of collection sites of mite predators of the cassava green mite, Mononychellus tanajoa (Bondar), in an international biological control program. Contingency TABLES were built using Dice's index as an indicator of significant associations between pairs of species. This analysis enabled the identification of plant and mite species typically found together, indicating interspecific interactions or similar ecological requirements. Finally, a cluster analysis was used to group sites containing similar assemblages. These sites exhibit comparable chances of harboring a given species. Applied at the species-group level, the analysis may assist in better defining sites for the collection of natural enemies to be released in a given region, improving the chances of establishment.

AbstractMononychellus tanajoa (Bondar), a spider mite new to Africa, was discovered on cassava in Uganda in 1971. This exotic mite of Neotropical origin has since spread to 27 countries, causing an estimated 13–80% reduction in cassava yield. The history of its introduction and spread in Africa is reported, and present knowledge on the taxonomy, biology, ecology and pest status of the mite, and the evolution of strategies to control it are reviewed. While attempts have been made to control M. tanajoa, it remains a serious pest in most areas. The prospects for classical biological control as an appropriate control strategy are discussed.
