For six months, 600 berries were randomly collected monthly at each site. The presence of <em>neem</em> oil extract (<em>Azadirachta indica Juss</em>.) fungus was observed on berries infested by the borer beetle. Rates of borer insect induced mortality to <em>neem</em> oil extract (<em>Azadirachta indica Juss.)</em> 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.</p> ER -
