Working Group 1: Symbiosis Biology

Symbiosis is a generic term used to describe the association and interaction between different organisms e.g. bacteria-eukaryote and eukaryote-eukaryote. In WG1 we will be looking at the various symbioses that occur in insects and associated entomopathogenic nematodes (EPN). Such interactions can be mutualistic (Photorhabdus/Xenorhabdus and EPN, Buchnera and aphids), indifferent, pathogenic (Wolbachia and its hosts (Fig.2), Photorhabdus/Xenorhabdus and insects) or parasitic (nematodes and insects).

Working Group 2: Bio-active Molecules

Pathogenicity relies on tools to overcome the host defence mechanisms and to kill the host. These substances can have biocidal activity which could be used in plant protection. To successfully establish in the host these organisms produce substances like antibiotics which prevent other organisms to establish in their environment. These substances can have a potential for the pharmaceutical industry. Symbiotic interactions rely on communication between the partners. The objective of WG 2 is to identify and characterise these bioactive molecules.

Working Group 3: Biotechnology

WG 3 will promote the commercial exploitation of biocontrol nematodes and other symbiotic antagonists. Activities will concentrate on production biotechnology, downstream processing, storage, formulation and application technologies. The improvement of quality control procedures will help to standardize product stability. Another focus will be the search for new applications of biocontrol symbionts against pests in agriculture and horticulture and the support of field development aiming at an improvement of delivery systems and integration with other control measures. Cooperation between industry, extension services and academia will result in the development of appropriate technical instructions for nematode use.

Working Group 4: Interactions with Field Biota

This working group will focus on different interactions of biocontrol nematode/bacterial complexes in the target environment. The working group aims to gain more knowledge on the following aspects related to biocontrol nematodes: survival and persistence, biology and interactions with field biota, use in integrated pest management, surveys and monitoring, inoculative release and safety.

Working Group 5: Socio-economics

The objective of this working group is to bring together the technology generation and the technology transfer aspects of COST 850 and to promote internal communication within COST 850.

The issues and questions arising from the user community of farmers, consumers, advisors and dealers have to be "pulled" into the laboratory and research findings and output need to be "pushed" or communicated back to the field. This coupling is the focus of WG 5.

The diagram below depicts the study of the biological processes and the bioactive molecules, their commercial production and evaluation in target environments as different levels of the research and development puzzle, and the two-way process of integrating this research with the social and economic environment as the work of WG 5.
