The major insect pests of arabica coffee were coffee berry borer (CBB), scale insects, aphids, mealybugs, snout beetle, and stem borer. The scale insects, aphids, mealybugs, snout beetle, and stem borer infest Arabica coffee from seedling stage until maturity while CBB infests berries. Potential biological control agents associated with these major insect pests were also collected. Potential predators feeding on aphids, scale insects, and mealybugs were lady beetles (Coleoptera: Coccinellidae), namely: black lady beetle [Chilocorus nigritus (Fabricius)], orange lady beetle [C. circumdatus (Gyllenhall)], 16-spotted lady beetle [Tytthas pis sedecimpunctata (L.)], yellow spotless lady beetle (Illeis koebelei Timberlake); ant beetle (Coleoptera:Anthicidae):Anthicus sp.; brown lacewings (Neuroptera:Hemerobiidae):Hemerobius spp.; green lacewings (Neuroptera:Chrysopidae):Chrysoperla rufilabris sp. The Assassin bug (Hemiptera:Reduviidae) Zelus sp. Feeds on adult CBB. Potential parasitoids that emerged from scale insects were small wasps (Hymenoptera: Eulophidae): (Hemiptarsenus sp.);Encyrtidae (Anagyrus sp., Copidosoma sp., Chrysocharis sp., and Microterys sp.). No parasitoids emerged from aphids, mealybugs, snout beetles, stem borer, and CBB.
