Crop resistance to B. tabaci is one of the potentially most valuable resources that can be tapped in developing effective management systems for the pest. Omongo et al. (2012) report an international collaborative effort to identify possible resistance sources in cassava to B. tabaci. Significant differences were observed in the level of colonization and population growth by B. tabaci on different cassava genotypes, and such variability demonstrates the existence of sources of resistance in cassava that may be explored to increase crop productivity. Use of virus-resistant crop varieties is one of the most effective methods in controlling virus pandemics. Colvin et al. (2012) describe the results of a survey to assess the utilization and impact of tomato varieties resistant to a devastating virus in India. The results demonstrate that the new resistant varieties have been widely adopted by Indian growers with a concomitant decrease in insecticide use and an increase in profitability. Socio-economic studies of this type are necessary for the subjective assessment of the practical impact of new management technologies in the field and will promote the research and adoption of the most effective management means.
