In the workpackage dealing with the assessment of new methods in Integrated Pest Management (IPM), researches from the EUCLID project proved the efficiency of different types of macro-biocontrol agents (macro-BCA).
The first promising one is the parasitoid N. tutae against the tomato leaf minor T. absoluta. The tomato greenhouse experiment lead at National Institute of Research in Agronomy (INRA, France) stressed a significant efficiency of the parasitoid on the reduction of the tomato leaf minor population after 5 weeks of exposure. The parasitoid has now to be tested in a field experiment but the first results leave us thinking that it might be one good technique to reduce the T. absoluta damages in tomato crops.
A second promising macro-BCA is a generalist predator from Dicyphus species. Its efficiency has been tested against the tomato leaf minor in tomato crops and show a very important decrease in the fruit injuries and number of T. absoluta larvae (Universidad de la Lleida, Spain). Moreover, the mirid bug also show higher efficiency in controlling the tomato leaf minor population with less individuals and no fruit injuries compared to a previously used mirid bug, N. tenuis (AgroBio, Spain).
