Susceptibility to termite attack of various tree species planted in Zimbabwe.
A trial containing 52 seedlots from 41 species of Australian, Central American and Zimbabwean trees at Kadoma, Zimbabwe, gave results showing major differences in overall survival and susceptibility to the fungus-growing termites Ancistrotermes latinotus and Macrotermes michaelseni. Species with more than 80% survival and less than 10% termite-caused deaths were Acacia holosericea, A. albida, A. salicina, A. plectocarpa, A. leptocarpa, A. difficilis, Enterolobium cyclocarpum and Senna atomaria. The survival of the standard species, Eucalyptus camaldulensis, was 34% with all deaths due to termite attack. The basal area per tree (at 30 cm height) of one provenance of the Australian species A. holosericea was significantly better than that of E. camaldulensis at the 5% level.
