Influence of ecological factors on larvae hatching of cystogenous species of nematodes

Understanding hatching process in plant parasitic nematodes has the potential to lead to new control strategies of these devistating pathogens, causing up to10–20% or $80 billion of crop loss globally (Nicol et al, 2011; Каплин, 2012). Although much research effort has been extended in elucidating the hatching factors, there has been no successful control strategy using their analogues to induce hatch in the field. This review examines development on this subject, focusing on the root diffusate, natural and inorganic compounds, as well as abiotic hatching factors (environmental temperature, moisture, aeration). They are assumed to have different impact on the hatching process of various cyst nematodes species despite of similarities in their biological features and life strategies. Notably, soil temperature and moisture play the vital role for species with a wide range of host plants whereas host plant diffusate is a key factor for highly specialized cyst nematode species. Appropriately investigated, it can favour development of control measures specified against targeted nematode species and boost their application in practice.
