Assessment of population dynamics and breeding habitat diversity of Culex quinquefasciatus
Abstract
Mosquitoes are the most important group of insects well known for the public health
importance. Mosquito vector control remains the cornerstone for the control of vector borne diseases. Larval control is the initial step in mosquito vector control, since they are killed at the breeding sites, prior to dispersing and infesting a community. Therefore, identification of breeding sites appears to be an easier means to check the mosquito population. Containers in and around human habitation are probably the most important factors facilitating the breeding of mosquito vectors. The present study was undertaken to determine the breeding preferences of Culex mosquitoes by conducting larval survey in 6 different localities of Ganjam district of Odisha state, India. Larval survey was carried out in outdoor as well as indoor containers and the Breeding Preference Ratio (BPR) was calculated. Result of current study showed a high BPR value (14.70%) for the indoor containers. In all most all study area, high rate of breeding preference was also observed for cement tanks in outdoor and plastic buckets in indoor studies. To support the study further, the Container Index (CI) and House Index (HI) percentages were also calculated. The CI% was found more in indoor and HI% was found more in outdoor studies respectively.
