Phenology Model Database
Sweetpotato Whitefly
Scientific name: Bemisia tabaci
Phenology models
predict timing of events in an organism's development.
For many organisms which cannot internally regulate their own temperature,
development is dependent on temperatures to which they are exposed in the environment.
Information in this database comes from published articles.
It may be used in conjunction with field monitoring and a
degree-day calculator.
Note: Before using a model that was not field tested in your location,
you should test the model
for one or more seasons under your conditions to verify
that it will work for you.
