Can plant breeding be a tool to control the rose hip flies(Rhagoletis alternata Fallen) in organic production?
Abstract: Rose hip flies are the major pest in cultivated rose hips as well as in wild-growingplants. During three seasons adult rose hip flies, Rhagoletis alternata, were captured on trapsplaced among different Rosa genotypes, which originated from a plant breeding program andincluded crosses of wild-collected Rosa species. Two of the nine traps captured more flies in allyears, which indicated differences in susceptibility between the genotypes. The question if plantbreeding can be a tool to control rose hip flies will be discussed in relation to previous studies inthis area.
