The access to the EPG-Calc Server is free and unlimited.


The development of EPG-Calc is promoted by Giordanengo P. (University of Picardie, Amiens, France / Sophia Agrobiotech Institute, Sophia Antipolis, France). The software and its web interface were originally written based on the design of earlier version, notably EPG-Calc 1 developed in VBA.

It is requested that use of this software be cited in publications as:
Giordanengo P. 2014. EPG-Calc: a PHP-based script to calculate electrical penetration graph (EPG) parameters. Arthropod-Plant Interactions, 8: 163-169


We are grateful to Dr Sébastien Dugravot (Institute for Genetics, Environment and Plant Protection, Rennes, France) and Dr Julien Saguez (Agriculture AgriFood Canada, Saint-Jean-sur-Richelieu, Canada) for their help in testing the script. Many thanks to Dr Freddy Tjallingii (EPG-Systems, Wageningen, Netherlands) for his invaluable help in calculation methods.
