St. Aegypti Case Study

Before applying any approach to control the dengue vectors, it is important to understand the biology (discussed in the section of “Biology of vector mosquitoes) and life cycle of Aedes mosquitoes which enables us to understand their population dynamics and their existence in nature. Life table parameters of St. aegypti provides base-line information on the potential for colonization in the laboratory, dengue transmission and control measures (Afrane, et al., 2007; Tejerina, et al., 2009) and provides reproductive strategies of St. aegypti (Christophers, 1960; Crovello, & Hacker, 1972). The various life history characteristics of mosquito includes female gonotrophic cycle, fecundity, egg hatching, stage-specific mortality, adult emergence
provide a considerable effect on the life cycle characteristics of St. aegypti and from these biological aspects, effective control strategies for disease transmission can be achieved (Grieco, et al., 2003; Tejerina, et al., 2009).
Although various studies has been conducted on the behavior of St. aegypti and St. albopicta (Balestrino, et al., 2014; Zheng, 2015), standardization of tools of rearing still needs to be developed (Zheng, 2015). Mass-rearing tools of vectors are useful for the application of various techniques such as SIT to sterilize the males, Incompatible Insect Technique (IIT) with the aid of which Wolbachia-infected males (Dobson, et al., 2002) and transgenic populations are introduced (Wilke, et al., 2009) in the field of vector
Blood meal is necessary for eggs maturation (Klowden, 1995) to complete the gonotrophic cycles (Christophers, 1960).St. aegypti mosquitoes can take multiple blood meals for the development of eggs (Scott, et al., 1993). The biting activity may tend to decrease in aged females (Goindin, 2015). Furthur studies on different parameters of immature stages of mosquitoes are essential in order to develop better tools and techniques in the field of vector control. The laboratory rearing of mosquitoes is of primary importance which readily provides sufficient adequate knowledge of various life table parameters including both aquatic and adult stages of the mosquitoes. The current study has been taken to understand the various life table parameters of Stegomyia aegypti. These life table parameters provide the measures to control the dengue fever and plays important role in dengue vector surveillance programs as dengue fever control depends on the control of vector population.
