The general objective of this study is to know the diversity of termites in papaya plantations in southern Côte d'Ivoire and thedamages caused by those termites. A papaya plantation was sampled using the standardized method for the rapid estimation of termite biodiversity. Two transects were plotted on diagonals 111 m long, 2 m wide and divided into 10 sections each. A last transect 100 m long and 2 m wide was drawn vertically in the middle of the farm and divided into 5 sections. A total of 25 sections have been delineated and searched. The results obtained show that five species are present in this papaya plantation. The species Pseudacanthotermesspiniger, Ancistrotermes crucifer, with respectively 70.05% and 12.79% of occurrence are the most abundant in the medium. Macrotermes bellicosus records the lowest occurrence at 1.08%. The fungus-growers make up the majority of termites harvested on the plot. And out of 68% of the attacked papaya trees, 38% has recorded structural damages, and 05% of the plants/trees would have been died because of termites, have been noticed. This work is a preliminary study that shows the impact of the papaya crop on termite biodiversity. However, the variation of termite communities according to the age of the plantation deserves to be studied.
