%X To understand the mechanism of infestation of stored
groundnut in farming areas, studies on the inventory and geographical
distribution of Caryedon species were
carried out in the tree savannah and in
producers¡¯ storage structures. The incidence of C. serratus in stored groundnut was evaluated. Inventory and geographical
distribution of insects belonging to Caryedon genus was achieved through a sampling in the savannah and producers¡¯
granaries. The
inventory and geographical distribution of insects was made throughout Burkina
Faso whereas the evaluation of the perforations of groundnut pods was made in
the western zone of the country. The results of the inventory showed the
presence of two species belonging to Caryedon genus which are C. serratus and C. crampelii. These species are found on
the agro-ecological zones
of the country. The survival and maintenance of Caryedon species genus are ensured by the presence of plants
belonging to various families such as Caesalpiniceae and Mimosaceae. The evaluation of the
losses caused by C. serratus in
producer¡¯s stored
groundnut revealed that the pods perforation rate varied according to the locality.
In Toussiana, the rate of perforated pods ranged from
53.72% to 100% in five months while in Karangasso Sembla, for the same conservation time, the rate was in the range from 2.8% to
35%. However it is C. serratus which
is responsible for the losses observed in the stored groundnut. Indeed, in the
western area of Burkina Faso where more than 25% of the production is realized,
