IOBC/WPRS is one of six Regional Sections of the International Organisation for Biological Control.
IOBC was established in 1955 to promote environmentally safe methods of pest and disease control in plant protection.

Members of WPRS are individual scientists, governmental, scientific or commercial organisations from 24 countries of Europe, Mediterranean region and the Middle East.

IOBC/WPRS encourages collaboration in promoting feasible and environmentally safe methods of pest and pathogen control.

IOBC/WPRS fosters research and practical application, organises meetings, symposia, offers training and information, especially of biological methods of control, but also of all methods, including chemicals, within an integrated pest management context. Major activities include development and standardisation of testing methods for effects of pesticides on beneficial species, pest and disease damage assessment, modelling in relation to pest and disease management, and the practical implementation of biological and integrated controls for pests and diseases of particular crops.
