The impact of these criniviruses on vegetable and fruit production has created a critical need for better understanding of host range and vector relationships in order to develop effective and efficient management practices. Criniviruses have large bipartite RNA genomes encodi

Moreover, control of insects is difficult because many are polyphagous and develop insecticide resistance quickly. Also, the use of these compounds favors the development of resistant populations, rendering their application counter-productive in the long

Biological control of whiteflies and other pests has been pursued through observation and utilization of natural enemy activity (e.g., Albajes et al. 2003)
