|Publication abstract=This study isolated and evaluated virulence of fungal entomopathogens of ''Xylosandrus compactus'' – an important pest of Robusta coffee in Sub-Saharan Africa. A survey was conducted in five farming systems in Uganda to isolate entomopathogens associated with ''X. compactus''. Four fungal isolates were screened for virulence against ''X. compactus'' in the laboratory at 1 × 10<sup>7</sup> conidia ml<sup>-1</sup> where an atoxigenic L-strain of ''A. flavus'' killed 70%–100% of all stages of ''X. compactus'' compared with other unidentified isolates which caused 20%–70% mortalities. The time taken by ''A. flavus'' to kill 50% of ''X. compactus'' eggs, larvae, pupae and adults in the laboratory was 2–3 days; whereas the other unidentified fungal isolates took 4–7 days. The concentrations of ''A. flavus'' that killed 50% of different stages of ''X. compactus'' were 5 × 10<sup>5</sup>, 12 × 10<sup>5</sup>, 17 × 10<sup>5</sup> and 30 × 10<sup>5</sup> conidia ml<sup>-1</sup> for larvae, eggs, pupae and adults respectively. A formulation of ''A. flavus'' in oil caused higher mortalities of ''X. compactus'' larvae, pupae and adults in the field (71%–79%) than its formulation in water (33%–47%). The atoxigenic strain of ''A. flavus'' could therefore be developed into a safe biopesticide against ''X. compactus''.
