Studies on the Survivorship of Aedes albopictus (Diptera: Culicidae) in vitro in differentiated breeding water from some parts of district Dehradun, Uttarakhand
Journal Title: Journal of Communicable Diseases - Year 2018, Vol 50, Issue 3
Abstract
Survival of arthropod vectors is one of the most important components of transmission of a vector-borne pathogen. In general, any influence on the vector that increases female longevity will increase the likelihood of survival through the extrinsic incubation period of the virus and the risk of disease transmission. Survivability rate of Aedes albopictus was determined during the month of April 2015 based on the breeding success on 03 experimental parameters viz., aged tap water, natural water and distilled water, by constructing a cohort (horizontal) life table. Survivability rate of Aedes albopictus was higher where eggs were emerged in natural water resources, followed by aged tap water. Basic reproductive rate (Ro ) of natural water resources accounted highest followed by aged tap water and distilled water. On performing the single way ANOVA, p value found higher than 0.001 concluding the fact that survivability was not independent of water resources. However, while performing Kaplan-Meier survivability test over age dependent parameters no such determining variation was registered. The value of Log rank test (Mantel Cox) abolish the null hypothesis suggesting the fact that there was significant difference in overall survival distribution among the three experimental parameters. Aedes mosquitoes are known to use their olfaction and visual cues to judge the chemical and physical factors present in the breeding water prior to egg laying. Thus, there must be some steps taken in order to analyse the chemicals released by these household deterrents so as to actively utilizing them in the Aedes management strategy
