responsible for great damage worldwide ( Sikora et al., 2005) . These nematodes reduce the quality of vegetables and cause yield losses around 50 to 80 % per annum worldwide ( Moens et al 2009 ; Siddiqi, 2000) . Beyond these most common root-knot species, currently, other species have been cited damaging P. vulgaris around the world, as M. enterolobii, M. chitwood, M. hapla and M. brasiliensis ( Brito et al 2003a , b ; Hafez & Sundararaj, 1999 ; Charchar & Eisenback, 2002) . Meloidogyneluci was detected on P. vulgaris in Distrito Federal, Brazil, but no

Necropsy and extensive parasitological examination of dead northern elephant seal (NES) pups was done on San Miguel Island, California, in February, 2015. The main interest in the current study was to determine if hookworms were present in NESs on San Miguel Island where two hookworm species of the genus Uncinaria are known to be present - Uncinaria lyonsi in California sea lions and Uncinaria lucasi in northern fur seals. Hookworms were not detected in any of the NESs examined: stomachs or intestines of 16 pups, blubber of 13 pups and blubber of one bull. The results obtained in the present study of NESs on San Miguel Island plus similar finding on Año Nuevo State Reserve and The Marine Mammal Center provide strong indication that NES are not appropriate hosts for Uncinaria spp. Hookworm free-living third stage larvae, developed from eggs of California sea lions and northern fur seals, were recovered from sand. It seems that at this time, further search for hookworms in NESs would be nonproductive.
