Gestion agroécologique des pucerons sur culture de pois par l'implantation d'une bande fleurie en bordure de parcelle

Abstract : The pea aphid, Acyrthosiphon pisum, is an issue on pea in Brittany. The crop is sensitive to pea aphid outbreaks from the flowering period. With the aim of reducing the use of protection products alternative methods are being tested as the conservation biological control. The agricultural cooperative Triskalia requested Nova-Flore to participate in a study. The aim of this study is to evaluate the impact of a flower strip on insects and pea production compared with a grassy strip, at three different dates. A comparative study has been realized to compare sampling methods. Insects are compared in the strips and in the crop with a distance effect to the strip. The results show that in the last samples, the abundance of Syrphid flies are higher in the flower strips and the beneficial insects are more numerous in the crop with flower strip at the edge. This may be linked to the flowering stage of the flower strip, low at the beginning and reaching 75% at the pea harvest. A distance effect to the strip is almost always stated. The abundance of insects decreases with the distance to the strip. The number of aphid mummies follow this rule, and mummies can be found at 75 m from the edge. An autumn sowing would be interesting to cover the pea sensitivity with the flowering stage of the flower strip.
