“…In temperate regions, most of cixiid planthoppers have been reported as univoltine, overwintering as nymphal stages underground. However, detailed information on their ecology and biology is restricted to a few pests such as Hylalesthes obsoletus Signoret (Leclant, 1968;Sforza et al, 1999;Sharon et al, 2005;Johannesen et al, 2008) that transmits stolbur phytoplasma to a number of cultivated plant species (Fos et al, 1992;Maixner, 1994;Sforza, 1998). However the emergence and re-emergence of vector-transmitted diseases associated with plant pathogenic prokaryotes have recently promoted investigation on these fulgoroids that include an increasing number of potential vector species (Gatineau et al, 2001Bogoutdinov, 2003;Danet et al, 2003;Jovic et al, 2007).…”
