Modelling of cassava brown streak virus spread by the insect vector Bemisia tabaci

A project developing ways to predict the spread of plant viruses under different environmental scenarios

Climate change is expected to intensify vector-borne viral diseases in future, by expanding the current geographical range of diseases and by creating new outbreaks.

In a changing environmental context, epidemiological modelling is increasingly valued because it provides data to understand virus transmission processes, develop interventions, and predict disease incidence and prevalence.

Currently, few models are available to integrate the complex interactions of

  • virus
  • host plant
  • insect vector, and
  • environment

to anticipate future spread of the disease.

This project is developing a temperature based model – that integrates the life cycle of Bemisia tabaci and their vector ability – for Cassava brown streak virus (CBSV).┬áThis model will enable analysis of the probability of virus transmission as affected by different future temperature scenarios driven by climate change.
