A study to ?nd out natural enemies of the co?ee cherry borer beetle Co?ea spp. hypothenemus hampei (H. hampei) (Ferrari) (Coleoptera, Scolytidae) was carried out in two ecologically di?erent sites of Cameroon: Moungo in the Littoral region of the country and Nkolbisson around Yaounde in  central region. For six months, 600 berries were randomly collected monthly at each site. The presence of neem oil extract (Azadirachta indica Juss.) fungus was observed on berries infested by the borer beetle. Rates of borer insect induced mortality to neem oil extract (Azadirachta indica Juss.) at Melong are: 78.6% in August, 67.6% in September, 42% in October, 63.2% in November, 39.7% in December. On the other hand, these rates at Nkolbisson are: 52.6% in October, 20% in November, 17.4% in December, 11.6% in January, 8.4% in February and 1,4% in March. From these observations, it was possible to carry out a research on the pathogenicity tests through its natural presence and  arti?cial-infection trials of the borer beetle with this fungus in order to protect better the co?ee grains with a biological product.
