Microbiology of the Hindgut and Survival of Amitermes evuncifer (Silvestri) on Some Nigerian Woods
T.O. Femi-Ola, E.Y. Aderibigbe and L. Awoyemi

The survival of Amitermes evuncifer (Silvestri) on five different Nigerian wood species: Terminalia superba Engl and Diels, Khaya grandifoliola C.D.C., Milicia excelsa Welw C.C. Berg, Mansonia altissima A. Chev and Brachystegia eurycoma Harms for seven days was investigated. Some physicochemical properties of the wood samples were also determined. The survival rate on Terminalia superba was highest (22.5%) and least on Mansonia altissima and Brachystegia eurycoma (0%), respectively. The other wood types had less than 15% live termites. Micrococcus luteus and Bacillus species were persistently isolated from the hindgut of the termites throughout the period of the no-choice food experiment. The total bacterial population in the hindgut of the termites declined from 104 to 102 cfu mL-1. The moisture content, density and pH of the wood samples ranged from 10 to 18%, 409 to 758 kg m-3 and 5.52 to 5.88, respectively. There was a high degree of correlation (R = 0.96; R2 = 0.922) between the amount of wood consumed and survival of A. evuncifer. However, the correlation coefficient between the amount of wood consumed and density of wood was negative (R = -0.675; R2 = 0.455).
