Abstract: The present study is conducted to estimate the effect of several climatic parameters on the seasonal abundance of Aedes mosquitoes. Based on the distribution of previously reported dengue cases, initially we have selected five districts of West Bengal and a weekly ovitrap-surveillance is conducted for one year. After successful obtaining of specimen from the ovipositors site, the larvae were brought to the laboratory and kept them into the different mosquito cages for future rearing and after emergence of adult, the mosquitoes were heat fixed and identified by using Dewinter Stereo Zoom microscope. After proper identification of the specimen, the specimens were curated on the appropriate levelled vials and then a simple mean and standard deviation were calculated for further statistical analysis. The Karl-Pearson coefficient correlation method is used to calculate statistical measurement. Comparing the correlation values among different kinds of environmental parameter, the r value of correlation between mosquito abundance and humidity exhibit much higher correlated specially in monsoon. On the above entomological survey, it has been observed that higher humidity and rainfall show the positive correlations with mosquito abundance and hence the effects on the spreading of DHF on proportional basis.
