Murphy, S.T. 1991 Insect natural enemies of coffee green scales [Hemiptera: Coccidae] in Kenya and their potential for biological control of Coccus celatus and C. viridis in Papua New Guinea.. Entomophaga 36(4): 519-529.

Notes: Summary/abstract in: French. Abstract: Surveys conducted in Kenya to find natural enemy species suitable to Papua New Guinea; primary parasites in central highlands found Metaphycus stanleyi, M. baruensis and Diversinervus stramineus to be dominant on C. celatus and C. alpinus; other predators were found to be common only in ant-free scale populations; Coccophagus rusti was the only natural enemy of C. viridis found. Keywords: biological control.
