In a constant changing context (reduction in the number of pesticides available) the control of Aphis gossypii populations in melon crops and of Thrips tabaci populations in leek crops using pesticides is increasingly difficult. Then, the search for alternative and/or complementary solutions is required. With this in mind, new strategies of protection based on the use of service plants (resource-plants, bankerplants, repellent-plants, screen and/or trap plants) or on the use of natural products such as kaolin have been developed and evaluated in the framework of the AGATH project, managed by the French Institute for Fruits and Vegetables (CTIFL) from 2013 to 2015, supported by the French Ministry of Agriculture and Food, and labelled by the PICleg consortium. The results showed that the setting up of resourceplants and/or banker-plants all around the fields could be effective in controlling A. gossypii in melon crops but not in controlling T. tabaci in leek crops, while it is the opposite as far as the use of repellentplants or kaolin are concerned. Finally, some strategies such as the use of screen and/or trap plants did not show any interest in the experimental context of the work carried out.
