Breeding preference of dengue vectors in Pakistan: An entomological investigation

摘要

Dengue fever (DF) and dengue hemorrhagic fever (DHF) are considered important reemerging arboviraldiseases in more than 100 tropical and subtropical countries of the world. The Entomologicalsurveillance of Dengue vector was carried out in six highly populated urban areas of Rawalpindi as perthe WHO procedure. A total of 492 houses were searched for Aedes breeding and 262 houses foundpositive. About 731 water containers were searched, out of which 281 found positive for Aedes. Breedingpreference ratio (BPR) was also calculated and discussed. The overall house index (HI), container index(CI), breteau index (BI) were 53.25, 38.44, and 57.11 respectively. Breeding Preference Ratio (BPR) wasobserved to be highest in water coolers (2.16), Discarded tyres (1.71), underground cement tank (1.69)and air condition water outlet containers (1.56). The results revealed that all the study areas ofRawalpindi city were found to positive for Ae. aegypti and Ae. albobictus.
