To contribute to their management, this study sought to identify genetic resources for resistance breeding within the world's largest cassava genebank, held at the International Center for Tropical Agriculture (CIAT), in Colombia. We compiled data from 89 field trials between 1980 and 2004 evaluating natural mite, thrips, and whitefly herbivory in hundreds of cassava genotypes. Highly susceptible genotypes were excluded from subsequent evaluations within one or two trials. Statistical analyses estimating resistance were therefore performed only for genotypes evaluated for a given pest in at least three trials. These analyses revealed potentially-useful genotype variation in resistance to Mononychellus tanajoa (Bondar), Aleurotrachelus socialis Bondar, and Frankliniella williamsi Hood. Based on this variation, we identified 129 potential sources of resistance to F. williamsi, 33 to M. tanajoa, and 19 to A. socialis. Leaf pubescence was positively associated with resistance to the three pests, and root cyanide was negatively associated with resistance to A. socialis. Our results support the potential for developing improved cassava cultivars with high pest resistance.

Evaluation of CGS resources and the fractional component of practical storage capacity is thus a major focus of research in both nations. In this paper, our purpose is to carefully evaluate the sources of uncertainty that propagate into regional-scale CGS resource estimates and assess the extent to which uncertainty may be reduced by applying increasingly informed levels of geologic characterization. We achieve this objective by focusing on two geologic basins of great similarity but with varying amounts of data the Illinois Basin in the United States and the Ordos Basin in China. Our investigation focuses on storage resource in deep saline formations because large-scale greenhouse gas mitigation is expected to require the use of this CGS resource. To accurately compare results from different basins and different nations requires applying a common methodology for estimating CGS resources. In this study we follow the methodology published by the U.S. Department of Energy.
