2.3-2 SPECIES <strong>OF</strong> TMtITES STUDIED Ancistrotermes cavithorax The ne., As of this species aro subterranean and polycalic with fungus combs in individual chambers. In Babba the nests w(, re some- times associated with old Cubitermes mounds. The fungus combs are fairly small (3-5 cm long)l and are eaten away at the bottom which is the oldest partl and are built up on the top and sideso They are Oencrally round in shape with a domed surface and flattened base, They sit in the chambers on projections of the fungus comb. They are fissured, brain-like structures, some of the rounded fissures penetrating through the whole comb. The mycotZtes sit within the fissures. The newer parts of the comb are lighter in colour than the older (Plate 2.3.2). A. cavithorax has both dimorphic soldiers nnd workers* They are a small specics, the major soldiers head width being around I mm Ofarris 1966). They are ca=xm in the forest at Rabba and in primary savanna woodlande Continuous cultivation results in their loss (Wood,, Johnson and Chiagu 1977). They feed on dead wood and plant litter and the outer bark of living trees and forage in rumays and under shoots of sub-soil* It forages most during the wet season but has more dry season activity than Microtermns (Collins 1977). The alates fly around 7*30 pm. the day after raing on several Occagions early in the rainy season. 50.
