Abstract
Soil samples around some fruit trees in samaru residential
areas of Ahmadu Bello University were taken and analysed to find
the nematodes present in them.
With the aid of a modified Baerman's funnel and decantation
methods, nematode fauna were extracted and analysed. A total of
about 17 genera of plant parasitic, freeliving and algal feeders
forms of nematodes were found present. They included plant
parasitic forms Rotylenchus spp., Tylenchus spp., Tylenchorynchus
spp., Hoplolaimus spp., Helicotylenchus spp., Hejucriconemoides
spp., Ditylenchus spp., Telotylenchus spp., ScuteUonema spp. and
Longidorus spp., the parasites of other nematodes, Mnonchus spp.
and Discolaimus spp., saprophagous forms such as Diplogasteroidea
spp., Drylaimus spp., Acrobeles spp., Dorylaimellus spp., and
the algal feeder, Eudorylaimus spp.
Helicotylenchus spp. were the most widely distributed,
occurring in relatively large populations at all sample sites and
around all fruit tree species sampled.
