PROGRAILIVE : Production PROtein GRAIn for LIVEstock



Context ans issues

  • Intensive livestock of western France strongly rely on American soy importation for cattle food, environmentally and economically unsustainable
  • Protein crops as pea, faba bean and lupine  locally produced, are more sustainable  alternatives to  soybean  but  these  crops  often  present variable yield between years, mainly due to the lack of efficient control of weeds, pathogens and pests
  • Intercropping protein crops and cereals could be a way to secure yield and manage weeds, pests, and pathogens
  • Concerning pests, in particular weevils and aphids, the aim  is to  define intercropping which could alter crop colonization by the pest or boost pest control by natural enemies
  •  We want first to describe the pest-natural enemies’ communities of  these  crops in western France, to study their population dynamics, the damages done, and the control strategies commonly applies by the farmers to identify levers of action
  •  Second  we  will  investigate  the  impact of within crop diversification on pest colonization and on parasitoids attraction and parasitism efficiency to define efficient pest suppressing intercropping
  • Historical capture data and genotype analysis to describe the pest pressure in the context of climate change and land use variation
  • Phytosanitary practices and damage observatory
  • 2-year observation and capture campaign of pests and natural enemies on a farm network
  • Chemical ecology studies of pests’ and natural enemies’ olfactory attraction to trophic resources
  • Isotopic labeling of parasitoids’ resources exploitation and movements within intercropping plots
