This study presents a review on the dynamics of seasonal variation of insects like Hemiptera in response to different edaphic factors, which include temperature, moisture, pH, organic carbon, inorganic nitrogen, phosphorus, sodium and potassium contents of an anthropogenous tropical forest, in West Bengal. The variation in abundance of Hemiptera is significant during the study period. The order showed its maximum population during summer (April) in 1st study year and in Monsoon (July) in 2nd study year, whereas it showed its minimum representation during winter (December and February) both in 1st and 2nd study year. Insects are generally well adapted to average condition during different season, but extremes can cause problem. From Pearson’s correlation of study, it is observed that the population abundance of a few species is significantly correlated with the concentration of temperature, moisture, pH, sodium, potassium and carbon. But according to the transformed results of Canonical Correspondence Analysis (CCA), it had appeared that increased concentration of temperature, sodium, potassium and carbon content had positive effect on increased Hemipteran population abundance but the concentration of moisture, pH, nitrogen and phosphorus could not affect the population abundance, which ware more specific. The present study helps to distinguish the actual cause of seasonal variation of Hemipteran populations, i.e., the effect of particular edaphic or other factors on them.
