Choice, toxicity, antifeedant tests and repellency effects of indigenous trees (Crotonrnmacrostachyus, Juniperus procera and Hagenia abyssinica) of Ethiopia on Macrotermesrntermite workers were studied under field and laboratory conditions. Fresh leaves of J. procerarnand C. macrostachyus fresh leaves attracted more worker termites than H. abyssinica.rnVolatiles collected from the leaves and wood stakes of the above mentioned plants, showedrnno significant differencee (P> 0.05) in attraction. Acetone, ethanol and water extracts of J.rnprocera and H. abyssinica showed no toxic effect on the insects after 24 hours of treatmentrnapplication. Aqueous extract of Azadirachta indica (neem) seed powder also showed norntoxicity. However, aqueous extract of H. abyssinica female flower powder killed all therninsects at three levels of extraction (10%, 15% & 20% w/v) and at 3ml level of applicationrnunlike 1ml & 2ml levels. Moreover, aqueous extracts of Milletia ferruginea seed powderrnextract showed 100% mortality at all the three extraction levels and 1ml, 2ml and 3ml rates ofrnapplication. C. macrostachyus stakes immersed into acetone, chloroform and ethanol extractsrnof H. abyssinca and J. procera saw dust for three minutes and buried around termite moundrnwere damaged at different levels after a month. C. macrostaychyus stakes were highlyrndamaged (82.9%) compared to J. procera stakes which were not even scratched. Thisrnindicated that worker Macrotermes termites feed less on H. abyssinica and do not feed on J.rnprocera.
