COMMERCIALISATION DES COSSETTES DE MANIOC AMENEES PAR LES CYCLISTES A KISANGANI

The purpose of this article on the marketing of cassava chips brought by the cyclists to Kisangani is to analyze the marketing of cassava chips by the producers them - selves as well as the retailers in Kisangani.  The starting question is to know if the producers of cassava come to sell them - selves their product on the market of Kisangani. Thus, we can ask these questions: -          This movement would it be beneficial for them? -          Would they gain by selling their cassava in Kisangani to supply themselves with various products of first need? -          Would their factors of production be well remunerated?   The assumptions hereafter were formulated, in regard to the interrogations raised above. From our opinion, we consider that this operation would not be economically advantageous for the "Tolekistes" or cyclists salesmen because they often ignore the elements concerned in the calculation of sell price (their deprivations and sacrifices). In order to check these assumptions, a survey questionnaire and a direct observation near the producers and retailers enabled us to achieve the goals of the departure. After examination and processing the data collected, the principal results which come out from this study are as follows: -          This operation is not financially advantageous to the cyclist's retailers. This is due to the fact that they often ignore the elements to be considered in the calculation of the cost price (their deprivations and sacrifices). Thus their profit margin is really a loss as a whole i.e. less than 52 000 FC (see table n°V). -          While for the farmers, this movement can be regarded as relatively beneficial because if a peasant intends to buy an English Wax part on the level of his surveyed village, he must engage 2,3 baskets of cassava chips whereas on the level of Kisangani, he loses only 1,3 baskets of cassava chips that is  practically half (see table VII).  In the light of the results obtained, it arises that the starting assumption was confirmed; this operation is thus not advantageous the "Tolékistes" or to cyclists salesmen in terms of income

Phoretic mites associated withRhynchophorus phoenicisFabricius(1880) (Coleoptera: Curculionidae) inthe Kisangani region, D.R. Congo

We sampled the mites present on individuals ofRhynchophorus phoeniciscollected atdifferent sites in the Kisangani region of the Democratic Republic of the Congo. Twospecies belonging to two families (Uroactiniidae and Urodinychidae) were identified:Centrouropoda almerodaiandUroobovella phoenicola. This is the first time thatC.almerodaihas been reported onR. phoenicis. The number of mites per adult may reach 39and differs between sexes and regions
