oa Journal of the Entomological Society of Southern Africa - The biology and control of Dirphya nigricornis (Olivier), a pest of coffee in Kenya (Coleoptera : Cerambycidae)
Two species of Yellow-Headed Borer have been recorded attacking coffee in Kenya. These are Dirphya nigricornis (Olivier) and Neonitocris princeps (Jordan). The original record was due to Anderson (1917) who listed Dirphya usambica (Kolbe) in a note on new coffee pests. D. usambica is now (Breuning, 1956) regarded as a form of D. nigricornis.
