Chabahar, located south east of Iran, is the most malarious region in the country. Objective: The main aim of this study was to quantify the spatiotemporal <a title="Learn more about Anopheles" href="https://www.sciencedirect.com/topics/medicine-and-dentistry/anopheles">Anopheles</a> population dynamics, response to climatic conditions in Chabahar. Methods: Satellite-based and land-based climatic data were used as explanatory variables. Monthly caught mosquitoes in 6 village sites of Chabahar were used as dependent variable. The spatiotemporal associations were first investigated by inspection of scatter plots and single variable regression analysis. A multivariate linear regression model was developed to reveal the association between environmental variables and the monthly mosquito abundance at a 95% confidence level ('P' ≤ 0.5). Findings: Results indicated that Anopheles mosquitoes can be found all year in Chabahar with 2 significant seasonal peaks from March to June (primary peak) and September to November (secondary peak). Results of the present study showed that 0.77 of yearly mosquito abundance emerges in the thermal range of 24°C to 30°C and the humidity range of 0.70 to 0.80 in Chabahar. Conclusion: According to the developed multivariate linear model, 0.88 of temporal variance of mosquito abundance, nighttime land surface temperature, and relative humidity of 15 Universal Time Coordinated (18.30 Iran) are the main drivers of mosquito population dynamics in Chabahar.Manuchehr FarajzadehMansour HalimiYousef GhavidelMahdi DelavariUbiquity PressarticleAnopheles mosquitoChabaharclimatic factorsspatiotemporal associationInfectious and parasitic diseasesRC109-216Public aspects of medicineRA1-1270ENAnnals of Global Health, Vol 81, Iss 5, Pp 694-704 (2016)
