Abstract:
Chrysops species have been recognized for its role as vectors in the transmission of human loiasis in Nigeria. This investigation was aimed at studying the occurrence and distribution of Chrysops species in Akamkpa community, cross river state. Two fly boys were used as human baits in the collection of adult Chrysops from each of the various villages in Akamkpa community, cross river state, Nigeria. Two species of Chrysops were identified. Chrysops dimidiata recorded significantly higher prevalence of 69.7% than Chrysops silacea 30.3% in all the sampling sites (p<0.05). Out of the 1299 Chrysops species caught in the entire study, the highest prevalence was reported during the late rainy season 916 (70.5%), while the least prevalence of 137 (10.6%) was reported during the late dry season (p<0.05). Two biting peaks 9-10 am and 3-4 pm were identified for Chrysops at all the sampling sites. Fly abundance was found to be higher in the morning hours than in the afternoon. The knowledge of the occurrence and distribution of Chrysops vectors will aid in the ongoing control program for human loiasis in Nigeria and the neighbouring countries where the vectors exist.
