Economic Importance:

Heterodera latipons, is considered to cause substantial yield losses in wheat throughout the world (Dababat et al., 2021).

Pathotypes with different virulence occur in H. latipons. The pathotypes are identified based on the reproductive ability of the cyst nematodes on wheat, barley and oat cultivars. The differentiation scheme called the �International Test Assortment� was derived from 7-11 virulent phenotypes which resulted from extensive selection pressure (Cook and Rivoal, 1998; Dababat et al., 2021).

For example, barley cultivars Ortolan, Morocco, KVL191, Bajo Aragon 1-1, Herta, Martin 403-2, and oat cultivars Sun II and Pusa Hybrid Bsi were resistant or moderately resistant populations of H. latipons from Turkey while barley cultivars Emir, Dalmatische and wheat cultivar Capa were susceptible. Based on these virulence results, Turkish populations were in the Ha1 group. Further analysis of virulence  on barley, oats and wheat classified them as either Ha41 or Ha51 (Dababat et al., 2021).

Heterodera latipons, studied on barley (cv Athenais) in Cyprus, completed only one generation per year  Juveliles penetrated roots at soil temperatures of 14.5C, 13 days after sowing.  young cysts were seen on roots54 days after sowing and embryonated egges were present in the cysts 98 days after sowing. (Philis, 1999).
