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.

Bemisia tabaci Genn. (Hemiptera: Aleyrodidae) and Frankliniella occidentalis (Thysanoptera: Thripidae) are major pests in greenhouse grown cucumber crops. Recently, Amblyseius swirskii Athias-Henriot. (Acari: Phytoseiidae) was shown an effective biological control agent of both pests Hence, perhaps both pests can be controlled simultaneously by this predator. However, with simultaneous infestation of both pests, synergistic effects, or interference could affect biological control and perhaps require changes in release rates of the predator. Thus, the aim of the present study was to evaluate different release rates of A. swirskii to control both pests under a worst case scenario of rapid immigration into a cucumber greenhouse. Two experiments were conducted, one simulating the influx of whiteflies alone (whitefly experiment) and the other immigration of whiteflies and thrips together (whitefly plus thrips experiment). Three treatments were compared in the whitefly experiment: (1) B. tabaci alone, (2) B. tabaci + 25 A. swirskii m -2 and (3) B. tabaci + 75 A. swirskii m -2. The high release rate was more effective than the low rate in controlling B. tabaci alone. The high rate was subsequently tested against B. tabaci and F. occidentalis for the whitefly and thrips experiment in which five treatments were compared: (1) B. tabaci alone, (2) F. occidentalis alone, (3) B. tabaci + 75 A. swirskii m -2, (4) F. occidentalis + 75 A. swirskii m -2 and (5) B. tabaci + F. occidentalis + 75 A. swirskii m -2. This rate of A. swirskii controlled whiteflies and thrips either alone or together. Therefore, 75 A. swirskii m -2 should be an adequate rate for controlling both pests either alone or simultaneously in cucumber greenhouses. © 2010 International Organization for Biological Control (IOBC).

Nesidiocoris tenuis Reuter (Het.: Miridae) is widely used as a biological control agent of whiteflies and other pests in greenhouse-grown tomatoes. It is typically released augmentatively some weeks after transplanting and needs several weeks to establish. Releasing N. tenuis prior to transplanting could accelerate its establishment. However, timing for releases could affect biological control and require changes in release rates of the predator. Because N. tenuis is also phytophagous it must be released at a rate which provides the best equilibrium between adequate biological control of Bemisia tabaci Genn. and acceptable injury to the crop. The objective of this study was therefore to evaluate different release rates for releasing N. tenuis prior to transplanting for maximizing control capacity and minimizing injury to crop. The study was carried out in two subsequent trials in which different release rates were evaluated under a worst case scenario of rapid immigration of the pest into a tomato greenhouse. In the first experiment (winter experiment), four treatments were compared: (1) B. tabaci (0 N. tenuis/plant), (2) B. tabaci + 0. 5 N. tenuis/plant, (3) B. tabaci + 1 N. tenuis/plant and (4) B. tabaci + 2 N. tenuis/plant. In the second experiment (summer experiment), the treatments were: (1) B. tabaci (0 N. tenuis/plant), (2) B. tabaci + 0. 5 N. tenuis/plant and (3) B. tabaci + 1 N. tenuis/plant. All the evaluated rates significantly reduced the population of whitefly and gave adequate control of the pest. However, only 0. 5 N. tenuis/plant did not increase crop damage compared to the treatment with no N. tenuis. © 2012 International Organization for Biological Control (IOBC).
