Meloidogyne floridensis was first found on Nemaguard, Nemared and Okinawa peach rootstocks in Gainesville, Florida in 1966. The rootstocks are resistant to M. incognita and M. javanica. The nematode was first assumed be a race of Meloidogyne incognita, but host range tests (Nyzcepir et al., 1998) suggested otherwise. Molecular studies confirm that M. floridensis differs from M. incognita and other root-knot nematodes (Handoo et al, 2004).
Esterase patterns of M. floridensis differed from all other root-knot nematodes tested (Handoo et al, 2004)
Florida, USA
Meloidogyne floridensis infests and reproduces on root knot nematode resistant Nemaguard, Nemared and Okinawa peach rootstocks.
Feeding site establishment and development typical of genus.
Nemaguard, Nemared and Okinawa peach rootstocks (Prunus persica), watermelon and tomato are hosts. Myrobalan plum and peppers are non-hosts (Handoo et al, 2004).
