Below ground and above plant-insect-microorganism interactions are complex regulate most of the developmental responses important crop plants such as tomato. We investigated influence root colonization by a nonmycorrhizal plant-growth-promoting fungus on direct indirect defenses tomato plant against aphids. The multitrophic system included Solanum lycopersicum ('San Marzano nano'), root-associated biocontrol Trichoderma longibrachiatum strain MK1, aphid Macrosiphum euphorbiae (a pest), parasitoid Aphidius ervi, predator Macrolophus pygmaeus. Laboratory bioassays were performed to assess effect T. interacting with plant, quantity quality volatile organic compounds (VOC) released development reproduction, behavior, behavior development. When compared uncolonized controls, whose roots colonized MK1 showed quantitative differences in release specific VOC, better population growth indices, higher attractiveness toward predator, quicker predator. These findings support novel strategies integrated control pests. species-specific or strain-specific characteristics these below ground-above remain be assessed.
