In fruit growing and horticulture, the brown marmorated stink bug, Halyomorpha halys and the green rice bug, Nezara viridula are currently serious invasive pests. Both stink bugs are very polyphagous. The brown marmorated stink bug infests almost all fruits, as well as vegetables and shrubs. The aim of the project is to further develop biotechnical plant protection using attractants and repellents to control the brown marmorated stink bug in organic farming with a focus on horticulture. By using encapsulated volatile organic compounds in the context of a novel push-pull-kill strategy (composed of push-and-pull and attract-and-kill), species-specific control of this invasive plant-sucking bug is to be achieved, thus establishing a new strategy for sustainable plant protection in organic and integrated farming that will later be transferable to other harmful bug species. In laboratory and semi-field trials, a known attractive mixture (aggregation pheromone together with a synergist) will be combined with a yet unknown arresting and feeding stimulating plant volatile and formulated in a suction medium. In addition, repellent plant scents will be formulated to provide efficacy enhancement and prevent edge effects. Efficacy trials will be conducted to determine the most effective kill component. For this purpose, the toxicity of a biological agent (azadirachtin) and some natural counterparts (B. thuringiensis, insect pathogenic fungi) will be compared under controlled conditions. The next step is to screen materials and methods for formulating these agents and to develop appropriate application strategies. For the insect-pathogenic microorganisms, cost-effective methods for mass propagation will be developed. Appropriate (co-) formulations will be developed and tested in laboratory and field trials. Leaflets are also being produced in collaboration with practitioners and consultants.
