Abstract: During the cross-sectional immature stage survey carried out to investigate the presence of larvae of Aedes aegypti in human habitation in Barnala, Punjab (India), potential breeding sites/containers (With or without larvae) were found in almost all houses surveyed. Larvae of Aedes aegypti were identified morphologically using a compound microscope. 32 houses out of 156 houses surveyed, had positive containers (With larvae). 57 containers out of 692 artificial water containers with potential for breeding were found to be positive. The larval indices, house index, 20.52% (95% confidence interval = 17.20–23.70), container index, 8.24% (95% C.I. = 7.28–9.38), and breteau index, 36.54% (95% CI = 34.24–38.66), were found higher than the critical levels. The water containers located away from direct sunlight and with ineffective lids had a higher larval density. TDS, EC, levels of the water in the containers as well as the material of the container had no discernible impact on the presence of Aedes larvae, according to the present investigations.
