EVALUATION OF COMMON POTENTIAL BREEDING SITE FOR ADES AGYPTI IN DISTRICT SWAT

Abstract

Objectives: The aim of this study was to identify potential breeding sites.
Methods and materials: It was a descriptive study conducted in August-September 2019. Secondary data (2018) of indoor and outdoor vector were analyzed to identify common potential
breeding sites. Breteau Index (BI), house index (HI) and Container index (CI), were calculated
using WHO standard formulae.
Results: During out door surveillance; stagnant water was found the most common breeding site
(n=169, 33%) while the least common site was leaking water taps (n=4, 0.8%). Other common
sites were water tanks which were 18% (n=93) followed by used tires 17% (n=87), water drums
13% (n=67), Garbage utensils 9% (n=46) and fl ower pots 4.4% (n=7). During indoor surveillance
water drums were the most common potential breeding site (n=414, 45%) while water plats for
birds were the least common site (n=4, 0.4%). Other common sites were water tanks 19% (n=178)
followed by Flower pots 13.5% (n=124), garbage utensil 13.2% (n=121), leaking water tap 4.4
% (n=41), used tires 2.5% (n=23) and stagnant water 1% (n=10) Breteau index (BI) was 0.06,
house index (HI) was 0.47 while Container index (CI) was 0.069.
Conclusion: Mechanical destruction of the all the positive potential breeding sites found in this
study can easily be managed requiring no additional cost and technical expertise. Therefore, mass
awareness about mechanical destruction of the potential breeding sites may play elementary role
in dengue fever prevention.
