Bed bugs as ectoparasites of humans are expanding in the world. Their geographical distribution has undergone major changes, particularly in connection with the globalization of trade, the movement of travelers and the anarchic urbanization of major cities. Following repeated complaints and requests for disinsection, bed bug collections were carried out in the cities of Abidjan, Grand Bassam, Anyama, Agboville, Yamoussoukro, Bouaké and Guiglo. The objective of this study was to determine the species of this ectoparasite in Côte d'Ivoire, with a view to efficient control. Thus, two species were identified: Cimex hemipterus and Cimex lectularius. C. hemipterus appears to be more represented in infestations than C. lectularius at 77.9% (n=868). In the case of C. lectularius, it accounted for only 22.1% (n=246) of infestations in the surveyed locations. Fisher’s test on the proportions of the two species revealed a highly significant difference (p<0.001) between them. Bed bugs are therefore present in Côte d’Ivoire and the dispersal of collection sites provides an overview of its geographic distribution. It also reflects a worrying health situation to which solutions must be found.
Key words: Diagnosis, Cimicidae, ectoparasites, Côte d’Ivoire.
