Results revalead that symptoms were observed in all parts (100%) of Franceville, with attacked trees ranging from 3.33 to 90%. The pest injury ranges from little foliage brown spots to complete tree defoliation. A predatory mirid diagnosed as Stethoconus praefectus (Distant) (Hemiptera: Miridae) was recorded feeding on the avocado lace bug P. perseae. Typical symptoms and both insect pictures were provided. Further studies are needed to highlight the pest distribution in the country and the predatory effectiveness.
