Abstract
Cimex hemipterus (f.), or tropical bed bugs, is an ectoparasite that primarily feeds on human blood. Tropical bed bugs have recently become in public health and are of social and economic importance. This study aimed to determine bed bug infestation, identify the bed bug species, and determine the level of awareness among the iraqi community regarding bed bug infestations in iraq. This study also examines the genetic structure and diversity of c. Hemitpterus populations in iraq. Bed bug infestation dynamics were determined by surveying 18 infested sites, including private homes, local hotels, and workers’ dormitories, across eight iraqi governorates between 2020 and 2021. Bed bug samples were collected from each infested site for further study. From the survey, most bed bug infestations in iraq primarily stem from migrant workers and the reuse of second-hand furniture and clothing. In terms of preferred harborage, wooden furniture was the common source (91.6%). Although a large number of respondents (43.8%) expressed "somewhat concerned" about bed bug infestations in iraq, there was a high level of unawareness (53.3%) regarding bed bug infestations. The mean pronotum width-to-length ratio of collected bed bug samples was less than 2.5mm these samples then underwent for molecular identification through partial sequences of mitochondrial coi and 16s rrna. Based on their morphological characteristics and dna sequence data, it can be affirmed that all collected bed bugs were c. Hemipterus. Moreover, the results indicated that c. Hemipterus is the sole bed bug species in iraq.
