Abstract

Studies on the geographical distribution and hosts of Tylenchuluspalustris were conducted over a 3-year period in Florida and Bermuda. Tylenchulus palustris was found on Aster elliottii and Liquidambar styraciflua roots in swamps of northern and central Florida. It was detected also on Borrichia arborescens and B. frutescens roots in tidal marshes of northern Florida and coastal rocklands of southern Florida and Bermuda. Posterior bodies of T. palustris swollen females from Bermuda did not differ from those of the paratypes; however, second-stage juvenile bodies and male tails from Bermuda were longer than those of the paratypes. Greenhouse host tests indicated that Mikania scandens is a host of T. palustris but not of T. semipenetrans. Key words: aster, Aster elliottii, Bermuda, Borrichia arborescens, Borrichia frutescens, citrus nematode, climbing hempweed, ecology, Florida, host range, Liquidambar styraciflua, Mikania scandens, sea oxeye, sweet gum, Tylenchulus palustris, Tylenchulus semipenetrans.
