Abstract:
Introduction
Nowadays, the rapid expansion of Asian tiger mosquito, Aedes albopictus (Diptera: Culicidae), around the globe has been warned by various articles. This study was aimed to determine the weight and priority of some meteorological and climatic variables on the presence possibility of this dengue vector by the analytical hierarchy process (AHP), in the south east of Iran.
Materials and methods
Effective factors on existence of Ae. albopictus were obtained through literature reviews and selected by international researchers. Weight and priority of eight parameters including precipitation, relative humidity (RH), temperature, land use anthropization, altitudes, wetlands, normalized difference vegetation index (NDVI) and Distance from border were obtained through completed matrix table and Expert Choice ver.11.0 software. Before that, a pair wise comparison matrix table including mentioned factors was prepared. It was completed by 11 academic professors around the world from Belgium, France, Germany, Iran, Italy, Spain, Sri Lanka and United Kingdom, published authoritative articles on Ae. albopictus ecology.
Results and discussion
The results on criteria weighting and priority showed that land use anthropization factor had the maximum weight (0.274) and the greatest priority among effective parameters on presence of Ae. albopictus. It was followed by temperature, altitude and precipitation parameters. The wetland with weight 0.042 had accounted the lowest priority. The inconsistency of this analysis was 0.03 with no missing judgments. This is the first modelling study in Iran for predicting areas with the possible presence of Ae. albopictus. A modelling study by using geographic information system along with field sampling can be conducted based on these results. Also, further and complementary modelling studies are suggested in northern regions of Iran, where the presence possibility of this species has been predicted in Global maps papers.
