BACKGROUND Secure and sustainable food production in terms of quantity and quality is a major challenge facing human societies. However, food security is continuously threatened by current and invasive pest species. EU regulations for the use of pesticides are getting stricter to ensure food safety and protect ecosystem health. Biocontrol of agricultural pests by using natural enemies has great potential to deal with these two demands. CHALLENGE Controlling novel exotic pests often involves importing non-native natural enemies. Such practices are undesirable as it poses risks to local biodiversity. Optimizing existing and native biocontrol agents can reduce the dependence on imported natural enemies. OBJECTIVE BINGO will advance current knowledge in biocontrol practice through the use of natural genetic variation and by simultaneously training 13 young researchers in an extensive suite of interdisciplinary skills. This will allow them to improve the efficiency of biological pest control through selective breeding of natural enemies in a broad range of agricultural systems and environmental conditions. HOW The research projects will address current bottlenecks in biocontrol, for rearing, monitoring and performance, that include a broad range of scientific disciplines and in which state-of-the-art population genomics will be applied. Industry has a pivotal role by providing the problems for research, training, and by translating the results to capacity building and increased competitiveness. RELEVANCE BINGO will deliver improved biocontrol agents, knowledge on the genetic organisation of traits related to agents’ performance, genetic markers for monitoring and risk assessment, and guidelines and protocols for genetic improvement of natural enemies. Crucially, BINGO will deliver eager ESRs that have the potential to thrive in professional environments in science, industry and public bodies to ensure that the biocontrol potential is met and implemented.
