Entomologist Joop C. van Lenteren (Wageningen University): 'Most farmers have become pesticide addicted during the past 60 years'
During the past 120 years, a large number of natural enemies has been collected and evaluated for use in augmentative biological control programmes. Particularly during the last 30 years many efficient species have been identified and currently at least 230 species are commercially available globally. Today, the commercial biological control industry is well organized, has developed mass production, shipment and release methods as well as adequate guidance for farmers. The industry has intensively collaborated with the public research sector in design of quality control programmes, which are applied during natural enemy production and shipment. The industry also cooperated in preparing environmental risk assessment methods for biological control agents. In several areas of agriculture augmentative biological control has obtained considerable successes and is now a reliable and appreciated element of IPM programmes. Despite all this progress, augmentative biological control is applied on a frustratingly small acreage.
