“…A total annual damage of 36.1 % of date-palm plantings, out of which 19.8 % were damaged beyond survival, was recorded in 1986 in Dutse. Wood and Kambal (1984) similarly recorded O.smeathmani and O.nilensis as causing damage to date palms in Dongola district of Sudan. Termite damage was probably the most important agricultural problem in the area, since 100 % of the trees were estimated to be infested at Dongola and one farmer indicated that he lost 1 -2 % of his trees each year.…”

“…Agwu (1981) listed workers and soldiers of Armitermes evuncifer as major pests of oil palms in Nigeria. Wood and Kambal (1984) also noted the damage done by Odontotermes smeathmani (Fuller) and O. nilensis Sjostedt to date palms in the Dongola district of Northern Sudan. Logan and EI Bakri (1990) further estimated an economic loss of fl33 Sterling per tree killed by termites in the same region in Sudan.…”

The termites, Odontotermes sp.nr. pauperans and O. smeathmani (Fuller) were found destroying young date palm trees during this study. Messor galla (Mayr.) (Hymenoptera) was often found in association with these termites. A total annual damage of 36.1 % of the palms out of which 19.8 % were damaged beyond survival, was recorded at Dutse date palm Sub – station in 1986. Rainfall and relative humidity were negatively correlated with severity of damage ( r = 0.902 and – 0.887). These correlations were significant at 5 % level. The partial correlation values obtained when rainfall, relative humidity and temperature were variously correlated with grades of damage, indicated that termite damage was more severe with increase in mean monthly temperature. Destruction of termitaria and removal of queens and treatment with insecticides are suggested to reduce incidence of termite damage in date palm plantings.
