Impact of the genetic diversity of three cyst nematodes on the effectiveness of root exudates to induce hatching

Cyst nematodes are sedentary endoparasites of plants which cause important economic losses worldwide. New nematode control measures needed since the removal effective chemical nematicides from market due to their negative impact on environment and human health. Induced hatching second-stage juveniles in absence host plant using root exudates, also named “suicide hatching”, could be a sustainable alternative method reduce population densities infested soils. Unfortunately, biocontrol methods often less agricultural fields than laboratory or greenhouse this to, among other reasons, different susceptibility populations exudate stimulation. Testing intra-specific variability would help anticipate any drop efficiency new strategy. A selection exudates species, maximizing level highlighted previous study, was tested representative genetic diversity for Globodera pallida, Heterodera schachtii carotae. Results showed significant differences between given species but not correlated with structure. Overall, provide high these three species. Surprisingly, broccoli induces European potato cyst G. pallida.
