Lobesia botrana is a microlepidoptera moth a common pest in European vineyards. Larvaes cause damages both by eating plant reproductive organs and indirectly by promoting the infection of grape berries by saprophytic pathogens.Since 1999, the Banyuls and Albères Agricultural Development Group (GDA) keeps track of infestations by L. botrana on control plots. Moreover, since 2012, thanks to the ANR TERVICLIM, the of Banyuls AOC region is covered by a network of temperature recording stations.This year, the GDA launches an IPM (Integreted Pest Management) plan based on mating disruption that requires the involvement of vine-growers. The aim of this paper is two-fold: the calibrating an agent-b…
DIVERSITE GENETIQUE ET PHENOLOGIE DE CYPERUS ESCULENTUS L. (CYPERACEAE) POUR UNE GESTION INTEGREE DE L'ESPECE DANS LES CULTURES DE HAUTE LANDE
2006
We studied the development, phenology, demography and genetic diversity of Cyperus esculentus (Cyperaceae), an invasive clonal perennial weed in the small-statured crops of Haute Lande, southwestern France. The goal was to understand its colonizing capacity and then make propositions for an integrated management of the species.The colonizing capacity of C. esculentus is linked to the huge subterranean vegetative development, with both foraging thanks to rhizomes and multiplication thanks to tubers. On the other hand, the local crop systems provide all the needs of the species: water, light and nutriments without competition by other weeds. Genetic analyses showed a low genetic diversity and…
