ABSTRACT
Introduction: Coconut is a perennial plant whose fruits are very useful in many fields. This culture is subject to many pests including termites. Objective: evaluate the impact of termites in coconut plantations. Methods: In order to identify the termites responsible for damage to coconut palms, a study was carried out at the Marc Delorme research station. Thus, a 3-month-old nursery, a 12-year-old coconut plot considered young and another 51-year-old considered old were the subject of our study. 100 m long and 2 m wide transects subdivided into 20 sections were developed as well as TSBF monoliths and systematic excavations were used for termite collection. Damage was observed on 133 plants on each of the plots and on plants chosen at random from the nursery. Results: The results obtained made it possible to identify seven (7) species of termites: Macrotermes bellicosus, Macrotermes subhyalinus, Ancistrotermes crucifer, Ancistrotermes cavithorax, Odontotermes pauperans, Odontotermes sp. and Amitermes spinifer. Macrotermes subhyalinus is a species common to all three environments. Two trophic groups have been identified. These are the fungus-growers and the wood-feeders with dominance of the fungus-growers. The attack rate varies from plot to plot. Young and old plots have an attack rate of 72.18% and 69.17% respectively. The highest attack rate was recorded on the nursery with 74.64%. Conclusion: It emerges from our work that all the studied plots are subject to termite attacks and it is therefore necessary to set up control methods.
