Abstract

Mosquito borne diseases are the most considerable public  health risks globally. Dengue fever infection is one of the  most important arboviral diseases in humans which are transmitted by Aedes aegypti (L.) mosquitoes. These Aedes  aegypti (L.) mosquitoes are highly persistent and can  survive almost any climatic conditions. Therefore, an  entomological survey was undertaken during 2015 to 2018  to evaluate the entomo-epidemiological risk of Aedes aegypti  (L.) mosquito borne diseases (VBD) in Udaipur district of  South Rajasthan to diminish potential global health risks  and prevent introduction of new vector borne diseases  (VBD). A cross-sectional immature stage survey was done  indoors in Region-I (Urban areas), Region-II (Periurban  areas) and Region-III (Rural areas) of Udaipur in 3645  houses. Mosquito larval sampling was conducted using  sieves, pipette, dipper or depending on container types.  Larvae were recognized morphologically and larval indices  were also considered. Repeated surveys were undertaken in  Urban, Periurban and Rural areas of Udaipur. A total of  8733 containers were inspected, and of these 1284 were  positive for Aedes aegypti (L.) mosquito larvae. Coolers,  Plastic Drums, Tires, Flower Pots, Mud Pots and  Discarded Buckets were most favourable for breeding. All  the entomological indices were found to be above the critical  level for all selected areas, prescribed by WHO, (2003;  2011). The larval indices i.e. House Index (HI), Container  Index (CI), Breteau Index (BI) and Pupae Index (PI) varied  from 10.20% to 11.76%, from 12.84% to 16.65%, from  31.85 to 41.89 and from 32.42 to 45.02 respectively. The  Periurban areas were found to be more prone to mosquito  breeding compare to other both areas (Urban and Rural).  To control these Aedes aegypti (L.) mosquitoes, a careful  and regular invigilation of the study areas is recommended.
