(Negash and Mohammed, 2004). Therefore, the economic
importance of this species to Ethiopia will depend very much
on the degree of aphid infestation in the future. Thus,
broadening of the genetic base through introduction of different
provenances and selection of resistant ones or introducing
biological measures (Pauesia junipeorum) may arrest the aphid
infestation and help to promote the development of large scale
C. lusitanica based industrial plantations.
