NAPPFAST Databases

 

Biological databases

 

Insect Development Database (IDD)

 

NAPPFAST relies on the use of specific biological parameters to run degree-day models. An Insect Development Database containing developmental temperatures and degree-day requirements for key insects has been developed for common insect pests and some beneficial insects (Nietschke et al., 2007).   This includes insects commonly found in literature searches and insect pests from the Global Pest and Disease Database. The Insect Development Database is available for download, but if you require a version of the database which includes PDF copies of the reference papers, email Roger.D.Magarey@aphis.usda.gov

 

Infection databases

 

The infection requirements of a number of fungal plant pathogens are listed in an excel spreadsheet – Plant Pathogen Parameter Library.  The infection requirements are the cardinal temperatures and  leaf wetness requirements.  The methodology has been described in Magarey et al. 2005.
