Determination of Age and Vectorial Capacity of Anopheles Maculipennis Sensu Lato in the Central Plateau of Iran

Background and Purpose: Islamic Republic of Iran has greatly reduced its malaria burden and has a national goal to eliminate malaria by ۲۰۲۵. The aim of this study was to determine the population dynamics of Anopheles maculipennis sensu lato, in relation to probable malaria transmission. For this purpose, the study was conducted in three villages in Isfahan Province of Iran, from April to March ۲۰۱۴. Materials and Methods: Two mosquitoes sampling methods were conducted, comprises human landing catch and human bed net collection. The results of this investigation were subjected to one-way ANOVA using SPSS. Results: A. maculipennis s.l. was found as a dominant vector with exophagic and endophilic behavior. Two peaks of blood feeding were observed, ۹.۰۰-۱۰.۰۰ p.m and ۱.۰۰-۲.۰۰ a.m. The gonotrophic cycle, survival rate, and life expectancy of the species were ۴, ۰.۸۲, and ۵ days, respectively. Malaria vectorial capacity of A. maculipennis was measured ۰.۰۱۲۸ and ۰.۰۵۹ for Plasmodium vivax and Plasmodium Falciparum, respectively. Conclusion: The findings indicate that there is a negative correlation between the temperature and daily age of A. maculipennis s.l. The method described can be used as a standard method to determine the daily age of Anopheles, as well as of other mosquito species since it is fast and precise and needs small samples. Survey on the age structure of vectors is very important as it is useful in monitoring the success of large-scale vector control measures.
