  1. The impact of tomato growing technology on whitefly populations (Aleyrodidae) Katja Žanić 1 , Gvozden Dumičić 1 , Marija Mandušić 1 Branimir Urlić 1 , Smiljana Goreta Ban 2 1 Institute for Adriatic Crops and Karst Reclamation, Split 2 Institute of Agriculture and Tourism , Poreč Funding: TomGraf; IP-2014-09-3365

  2. Project: Tomato grafting mitigates biotic stress caused by whiteflies (TomGraf; IP-2014-09-3365)  ARNOLD  BOUFON Bemisia tabaci  EMPERADOR  MAKSIFORT Trialeurodes vaporariorum

  3. Project: Tomato grafting mitigates biotic stress caused by whiteflies (TomGraf; IP-2014-09-3365) Grafting & vegetable TomGraf growing Plant stress phisiology & reproductive biology Plant metabolites Entomology - Whitefly populations The aim - We expect that selection of rootstock/s can be used as a useful tool in management strategy against whiteflies ensuring the satisfactory effect on yield and fruit quality components.

  4. Tobacco whitefly, Bemisia tabaci

  5. Tobacco whitefly, Bemisia tabaci PLANT DISORDERS Squash leaf curl virus (SLCV) i Tomato yellow leaf curl virus Watermelon chlorotic stunt (TYLCV) virus (WmCSV)

  6. Greenhouse whitefy – Trialeurodes vaporariorum LIFE CICLE

  7. Greenhouse whitefly, T. vaporariorum PLANT DISORDERS

  8. Resarch: Tomato grafting/rootstock effect on mitigation of biotic stress caused by B . tabaci and T . vaporariorum (2015) Experiment I Rootstock B . tabaci population density Clarabella Arnold Boufon Emperador Maxifort Non-grafted Self-grafted Experiment II Rootstock T . vaporariorum population density Arnold Boufon Emperador Maxifort Non-grafted Self-grafted

  9. Experiment details - (summer/autumn 2015) I B . tabaci mass reproduction Insect populations rearing

  10. Experiment details - (summer/autumn 2015) II T . vaporariorum mass reproduction

  11. Transplants production

  12. Experiments – tomato transplants in hydroponic system

  13. Experiment – transplants infestation I, 20. October

  14. RESULTS I The effect of tomato rootstock on adult density of B . tabaci B . tabaci adult population density was lower on grafted tomatoes compared to non-grafted or self-grafted tomatoes (three sampling).

  15. RESULTS II The effect of tomato rootstock on adult density of T. vaporariorum Number of T . vaporariorum adult individuals per leaf was lower on tomato plants grafted onto the rootstock Buffon compared to non-grafted or self- grafted tomatoes (three samplings).

  16. CONCLUSION The results can be applied in an integrated protection against B . tabaci and T . vaporariorum
