Deguine Jean-Philippe, Tho Can. 2022. Agroecological management of fruit flies. . PPRI, ASEA, ASSET. Hanoï : PPRI, Résumé, 1 p. Mini-conference on Agroecological Crop Protection (ACP): the Case of Fall Army Worm and Fruit Flies, Hanoï, Viet Nam, 3 Juin 2022.

Résumé : This presentation concerns the application of the concept of agroecological crop protection (ACP) to the case of fruit fly management, both for fruit and vegetable crops. The first part of the presentation deals with ACP, which can be considered as a set of scientific disciplines, as a set of agronomic practices and as a set of interactions between actors. Two major axes allow the optimization of the ecological functioning of an ecosystem: soil health and biodiversity above and within the soil. In addition to these axes, the phytosanitary strategy relies on other axes of crop protection: prevention of infestations or outbreaks, biological control. The implementation of the ACP strategy in the field is based on two main threads: an ecological thread and an ordered sequence of practices: prevention, biodiversity, soil health, biological control and various other techniques. The use of chemical pesticides is not at the beginning of the strategy as it is the case today in agrochemical protection, but as a last resort if necessary. The second part of the presentation gives a concrete description of the ordered list of agroecological management practices for fruit flies, using concrete examples and illustrations. The third part of the presentation concerns the conditions for successful implementation of this strategy. There are new approaches to be adopted: a participatory approach that places farmers at the center of the system, a systemic approach where the crop plot is only one part of the agroecosystem, and reasoning scales expanded in time and space. This field application must also be accompanied before, during and after, on the technical and socio-economic levels.
