Abstract

Two sampling techniques used in East Africa on Antestiopsis species in Arabica coffee were evaluated for effectiveness. Visual inspection as a sampling technique gave lower means per tree than test-spraying, implying that the latter may be more accurate. The advantages of both methods are discussed. © 1989 Taylor and Francis Ltd.
