Abstract
AbstractPhytonematode infections are a major constraint to agriculture and can cause pre-harvest losses of up to one-third of the crop in affected fields. With increasing restrictions on the use of chemical pesticides due to environmental and human hazards, and increasing nematode pressure due to climate change, soil degradation and agricultural intensification, more sustainable ways to manage such plant pests are needed to meet the growing demand for food. Therefore, the reproduction of thermophilic Meloidogyne spp. was evaluated in comparison with that of the northern root-knot nematode Meloidogyne hapla on the wild strawberry Fragaria vesca vs. semperflorens cv. Alexandria, a potential source of resistance to nematode infection. M. hapla showed a high reproductive rate in F. vesca, while the thermophilic Meloidogyne species tested showed significant lower reproductive rates. This suggests that F. vesca vs. semperflorens cv. Alexandria, although not resistant to the nematode species tested, could be used in a management system to down-regulate nematode pressure. In addition, this study helps to reinforce the importance of crop wild relatives in the search for resistance traits to support a more sustainable agriculture.
