Attacks by Termites (Blattoptera: Insecta) in cassava crops (Manioth esculenta Crantz.) in Daloa (Center-West, Côte d'Ivoire)

A study was carried out on the attack of termites in three cassava plots located in the zone of Daloa (town in the center-west of the Côte d’Ivoire). The main objective of this study was to ensure a sustainable productivity of cassava in the Daloa region by controlling termite’s pests of cassava crops according to the phenological stage, namely: the plot of cassava at the small stalk stage, the plot at the tuber production stage and the plot at the harvest stage. To this end, systematic excavations were carried out in the sections along the transects and plant-by-plant sampling in order to inventory the different species of termites on the plots and to highlight the damage they cause. This made it possible to identify 4 species of termites: Odontotermes sp., Macrotermes bellicosus, Pseudacanthotermes militaris and Nasutitermes latifrons, of which 1 species is common to all three environments. The comparative analysis of the different study environments showed that the plots at the production stage and at the harvest stage are the most colonized by termites. Odontotermes sp. observed only in plots at the small stage, as well as Nasutitermes latifrons which are only present on the plot at the production stage. Pseudacanthotermes militaris are best represented on all three plots.
