Abstract
Surveys were conducted during September and October 2002 to identify the stylet-bearing nematodes associated with date-palm in
Khuzdar district, Balochistan, Pakistan. The nematodes recorded were namely Tylenchus Bastian, 1865 sp.; Merlinius Siddiqi, 1970;
Helicotylenchus indicus Sher, 1963 Psilenchus hilarulus Siddiqi, 1963; Aphelenchoides Fischer, 1984; Meloidogyne incognita (Kofoid
and White) 1919, Chitwood, 1949 and Xiphinema americanum Cobb, 1913.
The similarity between the localities based on the qualitative (presence/absence) nematode data was calculated using Jaccard’s
coefficient of similarity. The dendograms derived from hierarchical agglomerative clustering of twelve locations of Khuzdar district
showed the largest group with five localities. This group was characterized by high density of H. indicus; X. americanum and M.
incognita.
