The aim of this study was to untanglethe trophic network involving C. bidens as prey. Molecular techniques along with predator activity surveys were employed to evaluate predation on psylla. Feeding on C. bidens was detected for five predators: Chrysoperla externa, Chrysopidae sp., Hemerobiidae sp., Harmonia axyridis and Cycloneda sanguinea. All these predators begin to feed earlier in the season, apart from C. externawhich fedds from the third psylla generation. These results will allow the development of strategies to increase the presence of these predators in the orchards.  © 2022 Informa UK Limited, trading as Taylor & Francis Group  aChrysoperla externa  aConservation biological control  aCycloneda sanguinea  aHarmonia axyridis  aNative predators1 aCABRERA, N.1 aCLAVIJO, F.1 aMUJICA, V.1 aGONZALEZ, A.1 aSIRI, M.1 aLAVANDERO, B.  tInternational Journal of Pest Management, 2022, vol. 68, issue 4: "Uruguayan Society of Phytopathology (SUFIT): Plant protection for a sustainable agriculture", p.390-401. doi: https://doi.org/10.1080/09670874.2022.2135181
