Abstract
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, 70% of groundnut stocked without treatment is
destroyed by this insect after only four months of storage.
