Abstract: 

To identify the tylenchs associated with fruit trees, 140 soil samples were collected from the rhizosphere of several fruit trees in Jiroft area (Kerman province, Iran) in 2001-02. Nematodes were extracted from soil by sieving and through centrifugal sugar-flotation method. The specimens were killed, fixed by hot solution of formaldehyde, glycerin and acetic acid, (FGA; 4: 1: 1), processed to anhydrous glycerin by the modified Seinhorst method (De Grisse, 1969) and then examined by light microscopy. The following 34 tylenchid species belonging to 19 genera were identified:

1-Aphelenchoides asterocaudatus     18-Geocenamusbrevidens

2- Aphelenchoides bicaudatus           19-Geocenamusrugosus

3- Aphelenchoides limberi                 20-Helicotylenchusmulticinctus

4- Aphelenchoides spicomucronatus   21- Helicotylenchus pseudorobustus

5- Aphelenchoides subtenuis              22- Hemicriconemoides chitwoodi

6- Aphelenchus avenae                      23-Hirschmanneillagracilis

7- Basiria berylla                               24- Hoplolaimus indicus

8- Basiria tumida                               25- Hoplolaimus seinhorsti

9- Boleodorus thylactus                      26- lrantylenchus visinus

10-Criconemellaxenoplax                    27- Paratylenchus coronatus

11-Ditylenchus myceliophagus             28- Pratylenchus neglectus

12-Filenchus andrassy                        29- Pratylenchus Thornei

13-Filenchus facultativus                     30-Psilenchus hilarulus

14-Filenchus misellus                          31-Psilenchus hilarus

15-Filenchuspolyhypnus                       32- Seinura demani

16-Filenchus vulgaris                           33- Tylenchorhynchus mashhoodi

17-Geocenamusalboranensis                34- Tylenchulus semipenetrans

Four species, namely Hirschmanniella gracilis; Hoplolaimus seinhorsti; Paratylenchus coronatus and Hemicriconemoides chitwoodi were new to nematode fauna of Iran, while Filenchus polyhypnus being recorded for the secound time in the country. Their morphological and morphometrical characteristics are described.
